Signs that a bunny is very sick include if it stops eating and drinking, if it has diarrhea, if it is unusually tired all of the time, or if it is bleeding.
Nausea (Latin nausea, from Greek - nausia, "ναυτία" - nautia, motion sickness", "feeling sick," "queasy" or "wamble") is a sensation of unease and discomfort in the upper stomach with an involuntary urge to vomit. It often, but not always, precedes vomiting. A person can suffer nausea without vomiting. (Greek ναῦς - naus, "ship"; ναυσία started as meaning "seasickness".)
Nausea is a non-specific symptom, which means that it has many possible causes. Some common causes of nausea are motion sickness, dizziness, migraine, fainting, gastroenteritis (stomach infection) or food poisoning. Side effects of many medications including cancer chemotherapy, nauseants or morning sickness in early pregnancy. Nausea may also be caused by anxiety, disgust and depression.
Medications taken to prevent and treat nausea are called antiemetics. The most commonly prescribed antiemetics in the US are promethazine, metoclopramide and ondansetron.
There are many causes of nausea. One organization listed 700 in 2009. Gastrointestinal infections (37%) and food poisoning are the two most common causes. While side effects from medications (3%) and pregnancy are also relatively frequent. In 10% of people the cause remains unknown.
Food poisoning usually causes an abrupt onset of nausea and vomiting one to six hours after ingestion of contaminated food and lasts for one to two days. It is due to toxins produced by bacteria in food.
Many medications can potentially cause nausea. Some of the most frequently associated include cancer and systemic chemotherapy regimens and general anaesthetic agents.
Nausea or "morning sickness" is common during early pregnancy but may occasionally continue into the second and third trimesters. In the first trimester nearly 80% of women have some degree of nausea. Pregnancy should therefore be considered as a possible cause of nausea in any women of child bearing age. While usually it is mild and self-limiting severe cases known as hyperemesis gravidarum may require treatment.
A number of conditions involving balance such as motion sickness and vertigo can lead to nausea and vomiting.
Nausea may be caused by stress and depression.. .
While most causes of nausea are not serious, some serious causes do occur. These include: diabetic ketoacidosis, brain tumor, surgical problems, heart attack, pancreatitis, small bowel obstruction, meningitis, appendicitis, cholecystitis, Addisonian crisis, Choledocholithiasis (from gallstones) and hepatitis, as a sign of carbon monoxide poison and many others.
Often no investigations are needed, however basic lab tests may be appropriate. If a bowel obstruction is possible, abdominal x-rays may be useful.
If dehydration is present due to loss of fluids from severe vomiting and/or accompanying diarrhea, rehydration with oral electrolyte solutions is preferred. If this is not effective or possible, intravenous rehydration may be required.
Dimenhydrinate (Gravol) is an inexpensive and effective medication for preventing postoperative nausea and vomiting. Meclozine is another antihistamine antiemetic. In certain people, cannabinoids may be effective in reducing chemotherapy associated nausea and vomiting. Ondansetron (Zofran) is effective for nausea and vomiting. Pyridoxine or metoclopramide are the first line treatments for pregnancy related nausea and vomiting. Many consider Medical marijuana to be an effective herbal remedy for nausea, where legal.
While short-term nausea and vomiting are generally harmless, they may sometimes indicate a more serious condition. When associated with prolonged vomiting, it may lead to dehydration and/or dangerous electrolyte imbalances. Repeated intentional vomiting, characteristic of bulimia, can cause stomach acid to wear away at the enamel in teeth.
Nausea and or vomiting is the main complaint in 1.6% of visits to family physicians in Australia. However only 25% of people with nausea visit their family physician. It is most common in those 15–24 years old and less common in other ages.

Abdominal pain (or stomach ache) is a common symptom associated with transient disorders or serious disease. Diagnosing the cause of abdominal pain can be difficult, because many diseases can cause this symptom. Most frequently the cause is benign and/or self-limiting, but more serious causes may require urgent intervention.
Acute abdomen can be defined as severe, persistent abdominal pain of sudden onset that is likely to require surgical intervention to treat its cause. The pain may frequently be associated with nausea and vomiting, abdominal distention, fever and signs of shock. One of the most common conditions associated with acute abdominal pain is acute appendicitis.
Selected causes of acute abdomen
When a physician assesses a patient to determine the etiology and subsequent treatment for abdominal pain the patient's history of the presenting complaint and physical examination should derive a diagnosis in over 90% of cases.
It is important also for a physician to remember that abdominal pain can be caused by problems outside the abdomen, especially heart attacks and pneumonias which can occasionally present as abdominal pain.
Investigations that would aid diagnosis include
If diagnosis remains unclear after history, examination and basic investigations as above then more advanced investigations may reveal a diagnosis. These as such would include
Butylscopolamine (Buscopan) is used to treat cramping abdominal pain with some success.

Diarrhea or diarrhoea (from the Greek , δια dia "through" + ρέω rheo "flow" meaning "flowing through") is the condition of having three or more loose or liquid bowel movements per day. The most common cause is gastroenteritis.
Oral rehydration solutions (ORS) with modest amounts of salts and zinc tablets are the treatment of choice and have been estimated to have saved 50 million children in the past 25 years. In cases where ORS is not available, homemade solutions are often used.
It is a common cause of death in developing countries and the second most common cause of infant deaths worldwide. The loss of fluids through diarrhea can cause dehydration and electrolyte disturbances such as potassium deficiency or other salt imbalances. In 2009 diarrhea was estimated to have caused 1.1 million deaths in people aged 5 and over and 1.5 million deaths in children under the age of 5.
Diarrhea is defined by the World Health Organization as having three or more loose or liquid stools per day, or as having more stools than is normal for that person.
Secretory diarrhea means that there is an increase in the active secretion, or there is an inhibition of absorption. There is little to no structural damage. The most common cause of this type of diarrhea is a cholera toxin that stimulates the secretion of anions, especially chloride ions. Therefore, to maintain a charge balance in the lumen, sodium is carried with it, along with water. In this type of diarrhea intestinal fluid secretion is isotonic with plasma even during fasting. It continues even when there is no oral food intake.
Osmotic diarrhea occurs when too much water is drawn into the bowels. If a person drinks solutions with excessive sugar or excessive salt, these can draw water from the body into the bowel and cause osmotic diarrhea. Osmotic diarrhea can also be the result of maldigestion (e.g., pancreatic disease or Coeliac disease), in which the nutrients are left in the lumen to pull in water. Or it can be caused by osmotic laxatives (which work to alleviate constipation by drawing water into the bowels). In healthy individuals, too much magnesium or vitamin C or undigested lactose can produce osmotic diarrhea and distention of the bowel. A person who has lactose intolerance can have difficulty absorbing lactose after an extraordinarily high intake of dairy products. In persons who have fructose malabsorption, excess fructose intake can also cause diarrhea. High-fructose foods that also have a high glucose content are more absorbable and less likely to cause diarrhea. Sugar alcohols such as sorbitol (often found in sugar-free foods) are difficult for the body to absorb and, in large amounts, may lead to osmotic diarrhea. In most of these cases, osmotic diarrhea stops when offending agent (e.g. milk, sorbitol) is stopped.
Exudative diarrhea occurs with the presence of blood and pus in the stool. This occurs with inflammatory bowel diseases, such as Crohn's disease or ulcerative colitis, and other severe infections such as E. coli or other forms of food poisoning.
Motility-related diarrhea is caused by the rapid movement of food through the intestines (hypermotility). If the food moves too quickly through the gastrointestinal tract, there is not enough time for sufficient nutrients and water to be absorbed. This can be due to a vagotomy or diabetic neuropathy, or a complication of menstruation][. Hyperthyroidism can produce hypermotility and lead to pseudodiarrhea and occasionally real diarrhea. Diarrhea can be treated with antimotility agents (such as loperamide). Hypermotility can be observed in people who have had portions of their bowel removed, allowing less total time for absorption of nutrients.
Inflammatory diarrhea occurs when there is damage to the mucosal lining or brush border, which leads to a passive loss of protein-rich fluids and a decreased ability to absorb these lost fluids. Features of all three of the other types of diarrhea can be found in this type of diarrhea. It can be caused by bacterial infections, viral infections, parasitic infections, or autoimmune problems such as inflammatory bowel diseases. It can also be caused by tuberculosis, colon cancer, and enteritis.][
Generally, if there is blood visible in the stools, it is not diarrhea, but dysentery. The blood is trace of an invasion of bowel tissue. Dysentery is a symptom of, among others, Shigella, Entamoeba histolytica, and Salmonella.
Diarrhea is most commonly due to viral gastroenteritis with rotavirus, which accounts for 40% of cases in children under five. (p. 17) In travelers however bacterial infections predominate. Various toxins such as mushroom poisoning and drugs can also cause acute diarrhea.
Chronic diarrhea can be the part of the presentations of a number of chronic medical conditions affecting the intestine. Common causes include ulcerative colitis, Crohn's disease, microscopic colitis, celiac disease, irritable bowel syndrome and bile acid malabsorption.
There are many causes of infectious diarrhea, which include viruses, bacteria and parasites. Norovirus is the most common cause of viral diarrhea in adults, but rotavirus is the most common cause in children under five years old. Adenovirus types 40 and 41, and astroviruses cause a significant number of infections.
The bacterium Campylobacter is a common cause of bacterial diarrhea, but infections by Salmonellae, Shigellae and some strains of Escherichia coli (E.coli) are frequent.
In the elderly, particularly those who have been treated with antibiotics for unrelated infections, a toxin produced by Clostridium difficile often causes severe diarrhea.
Parasites do not often cause diarrhea except for the protozoan Giardia, which can cause chronic infections if these are not diagnosed and treated with drugs such as metronidazole, and Entamoeba histolytica.
Other infectious agents such as parasites and bacterial toxins also occur. In sanitary living conditions where there is ample food and a supply of clean water, an otherwise healthy person usually recovers from viral infections in a few days. However, for ill or malnourished individuals, diarrhea can lead to severe dehydration and can become life-threatening.
Malabsorption is the inability to absorb food fully, mostly from disorders in the small bowel, but also due to maldigestion from diseases of the pancreas.
The two overlapping types here are of unknown origin:
Another possible cause of diarrhea is irritable bowel syndrome (IBS) which usually presents with abdominal discomfort relieved by defecation and unusual stool (diarrhea or constipation) for at least 3 days a week over the previous 3 months. Symptoms of diarrhea-predominant IBS can be managed through a combination of dietary changes, soluble fiber supplements, and/or medications such as loperamide or codeine. About 30% of patients with diarrhea-predominant IBS have bile acid malabsorption diagnosed with an abnormal SeHCAT test.
According to two researchers, Nesse and Williams, diarrhea may function as an evolved expulsion defense mechanism. As a result, if it is stopped, there might be a delay in recovery. They cite in support of this argument research published in 1973 which found that treating Shigella with the anti-diarrhea drug (Co-phenotrope, Lomotil) caused people to stay feverish twice as long as those not so treated. The researchers indeed themselves observed that: "Lomotil may be contraindicated in shigellosis. Diarrhea may represent a defense mechanism".
The following types of diarrhea may indicate further investigation is needed:
A severity score is used to aid diagnosis in children.
A rotavirus vaccine decrease the rates of diarrhea in a population. New vaccines against rotavirus, Shigella, ETEC, and cholera are under development, as well as other causes of infectious diarrhea.
Probiotics decrease the risk of diarrhea in those taking antibiotics. In institutions and in communities, interventions that promote hand washing lead to significant reductions in the incidence of diarrhea.
In many cases of diarrhea, replacing lost fluid and salts is the only treatment needed. This is usually by mouth – oral rehydration therapy – or, in severe cases, intravenously. Diet restrictions such as the BRAT diet are no longer recommended. Research does not support the limiting of milk to children as doing so has no effect on duration of diarrhea. To the contrary, WHO recommends that children with diarrhea continue to eat as sufficient nutrients are usually still absorbed to support continued growth and weight gain and that continuing to eat speeds also recovery of normal intestinal functioning. CDC recommends that children and adults with cholera also continue to eat.
Medications such as loperamide (Imodium) and bismuth subsalicylate may be beneficial; however they may be contraindicated in certain situations.
Oral Rehydration Solution (ORS) can be used to prevent dehydration. Standard home solutions such as salted rice water, salted yogurt drinks, vegetable and chicken soups with salt can be given. Home solutions such as water in which cereal has been cooked, unsalted soup, green coconut water, weak tea (unsweetened), and unsweetened fresh fruit juices can have from half a teaspoon to full teaspoon of salt (from one-and-a-half to three grams) added per liter. Clean plain water can also be one of several fluids given. There are commercial solutions such as Pedialyte, and relief agencies such as UNICEF widely distribute packets of salts and sugar. A WHO publication for physicians recommends a homemade ORS consisting of one liter water with one teaspoon salt (3 grams) and two tablespoons sugar (18 grams) added (approximately the "taste of tears"). Rehydration Project recommends adding the same amount of sugar but only one-half a teaspoon of salt, stating that this more dilute approach is less risky with very little loss of effectiveness. Both agree that drinks with too much sugar or salt can make dehydration worse.
Appropriate amounts of supplemental zinc and potassium should be added if available. But the availability of these should not delay rehydration. As WHO points out, the most important thing is to begin preventing dehydration as early as possible. In another example of prompt ORS hopefully preventing dehydration, CDC recommends for the treatment of cholera continuing to give Oral Rehydration Solution during travel to medical treatment.
Vomiting often occurs during the first hour or two of treatment with ORS, especially if a child drinks the solution too quickly, but this seldom prevents successful rehydration since most of the fluid is still absorbed. WHO recommends that if a child vomits, to wait five or ten minutes and then start to give the solution again more slowly.
Drinks especially high in simple sugars, such as soft drinks and fruit juices, are not recommended in children under 5 years of age as they may increase dehydration. A too rich solution in the gut draws water from the rest of the body, just as if the person were to drink sea water. Plain water may be used if more specific and effective ORT preparations are unavailable or are not palatable. Additionally, a mix of both plain water and drinks perhaps too rich in sugar and salt can alternatively be given to the same person, which the goal of providing a medium amount of sodium overall. A nasogastric tube can be used in young children to administer fluids if warranted.
WHO recommends a child with diarrhea continue to be fed. Continued feeding speeds the recovery of normal intestinal function. In contrast, children whose food is restricted, have diarrhea of longer duration and recover intestinal function more slowly. A child should also continue to be breastfed. A 2005 WHO manual for physicians and other senior health workers is quite emphatic regarding this point: "Food should never be withheld and the child's usual foods should not be diluted. Breastfeeding should always be continued." And in the specific example of cholera, CDC also makes the same recommendation.
While antibiotics are beneficial in certain types of acute diarrhea, they are usually not used except in specific situations. There are concerns that antibiotics may increase the risk of hemolytic uremic syndrome in people infected with Escherichia coli O157:H7. In resource poor countries, treatment with antibiotics may be beneficial. However, some bacteria are developing antibiotic resistance, particularly Shigella. Antibiotics can also cause diarrhea, and antibiotic-associated diarrhea is the most common adverse effect of treatment with general antibiotics.
While bismuth compounds (Pepto-Bismol) decreased the number of bowel movements in those with travelers' diarrhea, they do not decrease the length of illness. These agents should only be used if bloody diarrhea is not present.
Anti motility agents like loperamide are effective at reducing the duration of diarrhea. Codeine is used in the treatment of diarrhea to slow down peristalsis and the passage of fecal material through the bowels - this means that more time is given for water to reabsorb back into the body, which gives a firmer stool, and also means that feces is passed less frequently.
Bile acid sequestrants such as cholestyramine can be effective in chronic diarrhea due to bile acid malabsorption. Therapeutic trials of these drugs are indicated in chronic diarrhea if bile acid malabsorption cannot be diagnosed with a specific test, such as SeHCAT retention.
Zinc supplementation benefits children suffering from diarrhea in developing countries, but only in infants over six months old. This supports the World Health Organisation guidelines for zinc, but not in the very young.
Probiotics reduce the duration of symptoms by one day and reduced the chances of symptoms lasting longer than four days by 60%. The probiotic lactobacillus can help prevent antibiotic associated diarrhea in adults but possibly not children. For those who with lactose intolerance, taking digestive enzymes containing lactase when consuming dairy products is recommended.
World wide in 2004 approximately 2.5 billion cases of diarrhea occurred which results in 1.5 million deaths among children under the age of five. Greater than half of these were in Africa and South Asia. This is down from a death rate of 5 million per year two decades ago. Diarrhea remains the second leading cause of infant mortality (16%) after pneumonia (17%) in this age group.

Bleeding, technically known as hemorrhaging or hæmorrhaging (see American and British spelling differences), is the loss of blood or blood escaping from the circulatory system. Bleeding can occur internally, where blood leaks from blood vessels inside the body, or externally, either through a natural opening such as the mouth, nose, ear, urethra, vagina or anus, or through a break in the skin. Desanguination is a massive blood loss, and the complete loss of blood is referred to as exsanguination. Typically, a healthy person can endure a loss of 10–15% of the total blood volume without serious medical difficulties, and blood donation typically takes 8–10% of the donor's blood volume.
Hemorrhaging is broken down into four classes by the American College of Surgeons' advanced trauma life support (ATLS).
This system is basically the same as used in the staging of hypovolemic shock.
Individuals in excellent physical and cardiovascular shape may have more effective compensatory mechanisms before experiencing cardiovascular collapse. These patients may look deceptively stable, with minimal derangements in vital signs, while having poor peripheral perfusion. Elderly patients or those with chronic medical conditions may have less tolerance to blood loss, less ability to compensate, and may take medications such as betablockers that can potentially blunt the cardiovascular response. Care must be taken in the assessment of these patients.
The World Health Organization made a standardized grading scale to measure the severity of bleeding.
Bleeding arises due to either traumatic injury, underlying medical condition, or a combination.
Traumatic bleeding is caused by some type of injury. There are different types of wounds which may cause traumatic bleeding. These include:
The pattern of injury, evaluation and treatment will vary with the mechanism of the injury. Blunt trauma causes injury via a shock effect; delivering energy over an area. Wounds are often not straight and unbroken skin may hide significant injury. Penetrating trauma follows the course of the injurious device. As the energy is applied in a more focused fashion, it requires less energy to cause significant injury. Any body organ, including bone and brain, can be injured and bleed. Bleeding may not be readily apparent; internal organs such as the liver, kidney and spleen may bleed into the abdominal cavity. The only apparent signs may come with blood loss. Bleeding from a bodily orifice, such as the rectum, nose, ears may signal internal bleeding, but cannot be relied upon. Bleeding from a medical procedure also falls into this category.
'Medical bleeding' denotes hemorrhage as a result of an underlying medical condition (i.e. causes of bleeding that are not directly due to trauma). Blood can escape from blood vessels as a result of 3 basic patterns of injury:
The underlying scientific basis for blood clotting and hemostasis is discussed in detail in the articles, Coagulation, hemostasis and related articles. The discussion here is limited to the common practical aspects of blood clot formation which manifest as bleeding.
Certain medical conditions can also make patients susceptible to bleeding. These are conditions that affect the normal "hemostatic" functions of the body. Hemostasis involves several components. The main components of the hemostatic system include platelets and the coagulation system.
Platelets are small blood components that form a plug in the blood vessel wall that stops bleeding. Platelets also produce a variety of substances that stimulate the production of a blood clot. One of the most common causes of increased bleeding risk is exposure to non-steroidal anti-inflammatory drugs (or "NSAIDs"). The prototype for these drugs is aspirin, which inhibits the production of thromboxane. NSAIDs inhibit the activation of platelets, and thereby increase the risk of bleeding. The effect of aspirin is irreversible; therefore, the inhibitory effect of aspirin is present until the platelets have been replaced (about ten days). Other NSAIDs, such as "ibuprofen" (Motrin) and related drugs, are reversible and therefore, the effect on platelets is not as long-lived.
There are several named coagulation factors that interact in a complex way to form blood clots, as discussed in the article on coagulation. Deficiencies of coagulation factors are associated with clinical bleeding. For instance, deficiency of Factor VIII causes classic Hemophilia A while deficiencies of Factor IX cause "Christmas disease"(hemophilia B). Antibodies to Factor VIII can also inactivate the Factor VII and precipitate bleeding that is very difficult to control. This is a rare condition that is most likely to occur in older patients and in those with autoimmune diseases. von Willebrand disease is another common bleeding disorder. It is caused by a deficiency of or abnormal function of the "von Willebrand" factor, which is involved in platelet activation. Deficiencies in other factors, such as factor XIII or factor VII are occasionally seen, but may not be associated with severe bleeding and are not as commonly diagnosed.
In addition to NSAID-related bleeding, another common cause of bleeding is that related to the medication, warfarin ("Coumadin" and others). This medication needs to be closely monitored as the bleeding risk can be markedly increased by interactions with other medications. Warfarin acts by inhibiting the production of Vitamin K in the gut. Vitamin K is required for the production of the clotting factors, II, VII, IX, and X in the liver. One of the most common causes of warfarin-related bleeding is taking antibiotics. The gut bacteria make vitamin K and are killed by antibiotics. This decreases vitamin K levels and therefore the production of these clotting factors.
Deficiencies of platelet function may require platelet transfusion while deficiencies of clotting factors may require transfusion of either fresh frozen plasma or specific clotting factors, such as Factor VIII for patients with hemophilia.
Vomiting (known medically as emesis and informally as throwing up and numerous other terms) is the forceful expulsion of the contents of one's stomach through the mouth and sometimes the nose. Vomiting can be caused by a wide variety of conditions; it may present as a specific response to ailments like gastritis or poisoning, or as a non-specific sequela of disorders ranging from brain tumors and elevated intracranial pressure to overexposure to ionizing radiation. The feeling that one is about to vomit is called nausea, which often precedes, but does not always lead to, vomiting. Antiemetics are sometimes necessary to suppress nausea and vomiting. In severe cases, where dehydration develops, intravenous fluid may be required.
Vomiting is different from regurgitation, although the two terms are often used interchangeably. Regurgitation is the return of undigested food back up the esophagus to the mouth, without the force and displeasure associated with vomiting. The causes of vomiting and regurgitation are generally different.
Vomiting can be dangerous if the gastric content enters the respiratory tract. Under normal circumstances the gag reflex and coughing prevent this from occurring, however these protective reflexes are compromised in persons under the influences of certain substances such as alcohol or anesthesia. The individual may choke and asphyxiate or suffer an aspiration pneumonia.
Prolonged and excessive vomiting depletes the body of water (dehydration), and may alter the electrolyte status. Gastric vomiting leads to the loss of acid (protons) and chloride directly. Combined with the resulting alkaline tide, this leads to hypochloremic metabolic alkalosis (low chloride levels together with high −3HCO and CO2 and increased blood pH) and often hypokalemia (potassium depletion). The hypokalemia is an indirect result of the kidney compensating for the loss of acid. With the loss of intake of food the individual may eventually become cachectic. A less frequent occurrence results from a vomiting of intestinal contents, including bile acids and HCO3-, which can cause metabolic acidosis.
Repeated or profuse vomiting may cause erosions to the esophagus or small tears in the esophageal mucosa (Mallory-Weiss tear). This may become apparent if fresh red blood is mixed with vomit after several episodes.
Recurrent vomiting, such as observed in bulimia nervosa, may lead to destruction of the tooth enamel due to the acidity of the vomit. Digestive enzymes can also have a negative effect on oral health, by degrading the tissue of the gums.
Receptors on the floor of the fourth ventricle of the brain represent a chemoreceptor trigger zone, known as the area postrema, stimulation of which can lead to vomiting. The area postrema is a circumventricular organ and as such lies outside the blood–brain barrier; it can therefore be stimulated by blood-borne drugs that can stimulate vomiting or inhibit it.
There are various sources of input to the vomiting center:
The vomiting act encompasses three types of outputs initiated by the chemoreceptor trigger zone: Motor, parasympathetic nervous system (PNS), and sympathetic nervous system (SNS). They are as follows:
The neurotransmitters that regulate vomiting are poorly understood, but inhibitors of dopamine, histamine, and serotonin are all used to suppress vomiting, suggesting that these play a role in the initiation or maintenance of a vomiting cycle. Vasopressin and neurokinin may also participate.
The vomiting act has two phases. In the retching phase, the abdominal muscles undergo a few rounds of coordinated contractions together with the diaphragm and the muscles used in respiratory inspiration. For this reason, an individual may confuse this phase with an episode of violent hiccups. In this retching phase nothing has yet been expelled. In the next phase, also termed the expulsive phase, intense pressure is formed in the stomach brought about by enormous shifts in both the diaphragm and the abdomen. These shifts are, in essence, vigorous contractions of these muscles that last for extended periods of time - much longer than a normal period of muscular contraction. The pressure is then suddenly released when the upper esophageal sphincter relaxes resulting in the expulsion of gastric contents. Individuals who do not regularly exercise their abdominal muscles may experience pain in those muscles for a few days. The relief of pressure and the release of endorphins into the bloodstream after the expulsion causes the vomiter to feel better.
Gastric secretions and likewise vomit are highly acidic. Recent food intake appears in the gastric vomit. Irrespective of the content, vomit tends to be malodorous.
The content of the vomitus (vomit) may be of medical interest. Fresh blood in the vomit is termed hematemesis ("blood vomiting"). Altered blood bears resemblance to coffee grounds (as the iron in the blood is oxidized) and, when this matter is identified, the term "coffee ground vomiting" is used. Bile can enter the vomit during subsequent heaves due to duodenal contraction if the vomiting is severe. Fecal vomiting is often a consequence of intestinal obstruction or a gastrocolic fistula and is treated as a warning sign of this potentially serious problem ("signum mali ominis").
If the vomiting reflex continues for an extended period with no appreciable vomitus, the condition is known as non-productive emesis or dry heaves, which can be painful and debilitating.
Vomiting may be due to a large number of causes, and protracted vomiting has a long differential diagnosis.
Causes in the digestive tract
Causes in the sensory system
Causes in the brain
Metabolic disturbances (these may irritate both the stomach and the parts of the brain that coordinate vomiting)
Drug reaction (vomiting may occur as an acute somatic response to)
Illness (sometimes colloquially known as "stomach flu"—a broad name that refers to gastric inflammation caused by a range of viruses and bacteria.)
An emetic, such as syrup of ipecac, is a substance that induces vomiting when administered orally or by injection. An emetic is used medically where a substance has been ingested and must be expelled from the body immediately (for this reason, many toxic and easily digestible products such as rat poison contain an emetic). Inducing vomiting can remove the substance before it is absorbed into the body. Ipecac abuse can cause detrimental health effects.
Salt water and mustard water have been used since ancient times as emetics. Care must be taken with salt, as excessive intake can potentially be harmful.
Copper sulfate was also used in the past as an emetic. It is now considered too toxic for this use.
Hydrogen peroxide is used as an emetic in veterinary practice.
It is quite common that, when one person vomits, others nearby become nauseated, particularly when smelling the vomit of others, often to the point of vomiting themselves. It is believed that this is an evolved trait among primates. Many primates in the wild tend to browse for food in small groups. Should one member of the party react adversely to some ingested food, it may be advantageous (in a survival sense) for other members of the party to also vomit. This tendency in human populations has been observed at drinking parties, where excessive consumption of alcoholic beverages may cause a number of party members to vomit nearly simultaneously, this being triggered by the initial vomiting of a single member of the party. This phenomenon has been touched on in popular culture: Notorious instances appear in the films Monty Python's The Meaning of Life (1983) and Stand By Me (1986).
Intense vomiting in ayahuasca ceremonies is a common phenomenon. However, people who experience "la purga" after drinking ayahuasca, in general, regard the practice as both a physical and spiritual cleanse and often come to welcome it. It has been suggested that the consistent emetic effects of ayahuasca — in addition to its many other therapeutic properties — was of medicinal benefit to indigenous peoples of the Amazon, in helping to clear parasites from the gastrointestinal system.
There have also been documented cases of a single ill and vomiting individual inadvertently causing others to vomit, when they are especially fearful of also becoming ill, through a form of mass hysteria.
Most people try to contain their vomit by vomiting into a sink, toilet, or trash can, as vomit is difficult and unpleasant to clean. On airplanes and boats, special bags are supplied for sick passengers to vomit into. A special disposable bag (leakproof, puncture-resistant, odorless) containing absorbent material that solidifies the vomit quickly is also available, making it convenient and safe to store until there is an opportunity to dispose of it conveniently.
People who vomit chronically (e.g., as part of an eating disorder such as bulimia nervosa) may devise various ways to hide this disorder.
An online study of people's responses to "horrible sounds" found vomiting "the most disgusting." Professor Cox of the University of Salford's Acoustic Research Centre said that "We are pre-programmed to be repulsed by horrible things such as vomiting, as it is fundamental to staying alive to avoid nasty stuff." It is thought that disgust is triggered by the sound of vomiting to protect those nearby from, possibly diseased, food.
Fecal vomiting (aka stercoraceous vomiting) is a kind of vomiting, or emesis, in which partially or fully digested matter is expelled from the intestines into the stomach, by a combination of liquid and gas pressure and spasmodic contractions of the gastric muscles, and then subsequently forcefully expelled from the stomach up into the esophagus and out through the mouth and sometimes nasal passages. Though it is not usually fecal matter that is expelled][, it smells noxious. Alternative medical terms for fecal vomiting are copremesis and stercoraceous vomiting. Copremesis like all emesis may lead to aspiration. However, if contents of the large intestine are aspirated, severe or even fatal aspiration pneumonia results, secondary to the massive number of bacteria normally present distal to the ileocecal valve.][ Projectile vomiting refers to vomiting that ejects the gastric contents with great force. It is a classic symptom of infantile hypertrophic pyloric stenosis, in which it typically follows feeding and can be so forceful that some material exits through the nose.
An antiemetic is a drug that is effective against vomiting and nausea. Antiemetics are typically used to treat motion sickness and the side-effects of medications such as opioids and chemotherapy.
Antiemetics act by inhibiting the receptor sites associated with emesis. Hence, anticholinergics, antihistamines, dopamine antagonists, serotonin antagonists, and cannabinoids are used as anti-emetics.
Nausea and/or vomiting are the main complaints in 1.6% of visits to family physicians in Australia.

Bugs Bunny is a funny animal cartoon character, best known for his starring roles in the Looney Tunes and Merrie Melodies series of theatrical short films produced by Warner Bros. during the Golden age of American animation. His popularity during this era led to his becoming a cultural icon, as well as a corporate mascot of Warner Bros. Entertainment. Bugs is an anthropomorphic gray hare or rabbit who is famous for his flippant, insouciant personality, a pronounced New York accent, his portrayal as a trickster, and his catch phrase "Eh... What's up, doc?" (usually said while chewing a carrot). Bugs has appeared in more films (both short and feature-length) than any other cartoon character and is the ninth most-portrayed film personality in the world.
According to his 1990 "biography" Bugs Bunny: 50 Years and Only One Grey Hare, Bugs was born on July 27, 1940 in Brooklyn, New York in a warren under Ebbets Field, home of the Brooklyn Dodgers. In reality, he was brought to life by the animators and staff of Leon Schlesinger Productions (later Warner Bros. Cartoons): including Tex Avery, who directed Bugs' early definitive film A Wild Hare (1940); Robert McKimson, who created Bugs' definitive character design; and Mel Blanc, who originated the voice of Bugs.
A rabbit with some of the personality of Bugs, though looking very different, first appears in Porky's Hare Hunt, released on April 30, 1938. It was co-directed by Ben "Bugs" Hardaway and an uncredited Cal Dalton (who was responsible for the initial design of the rabbit). This cartoon has an almost identical plot to Tex Avery's Porky's Duck Hunt (1937), which had introduced Daffy Duck. Porky Pig is again cast as a hunter tracking a silly prey who is more interested in driving his pursuer insane and less interested in escaping. Hare Hunt replaces the little black duck with a small white rabbit. The rabbit introduces himself with the odd expression "Jiggers, fellers," and Mel Blanc gave the character a voice and laugh much like those he would later use for Woody Woodpecker. Hare Hunt also gives its rabbit the famous Groucho Marx line, "Of course you realize, this means war!" The rabbit character was so popular with audiences that Leon Schlesinger's staff decided to use it again.
The rabbit returns in Prest-O Change-O (1939), directed by Chuck Jones, where he is the pet rabbit of unseen character Sham-Fu the Magician. Two dogs, fleeing the local dogcatcher, enter his absent master's house. The rabbit harasses them, but is ultimately bested by the bigger of the two dogs.
The rabbit's third appearance comes in Hare-um Scare-um (1939), directed by Dalton and Hardaway. This cartoon—the first in which he is depicted as a gray bunny instead of a white one—is also notable as the rabbit's first singing role. Charlie Thorson, lead animator on the film, gave the character a name. He had written "Bugs' Bunny" on the model sheet that he drew for Hardaway. In promotional material for the cartoon, including a surviving 1939 presskit, the name on the model sheet was altered to become the rabbit's own name: "Bugs" Bunny (quotation marks only used, on and off, until 1944).
In the 1970s, Mel Blanc stated that another proposed name for the character was "Happy Rabbit." In the actual cartoons and publicity, however, the name "Happy" only seems to have been used in reference to Bugs Hardaway. In Hare-um Scare-um, a newspaper headline reads, "Happy Hardaway."
In Chuck Jones' Elmer's Candid Camera (1940) the rabbit first meets Elmer Fudd. This time the rabbit looks more like the present-day Bugs, taller and with a similar face—but retaining the more primitive voice. Candid Camera's Elmer character design is also different: fatter and taller than the modern model, though Arthur Q. Bryan's character voice is already established.
A Wild Hare, directed by Tex Avery and released on July 27, 1940, is widely considered to be the first official Bugs Bunny cartoon. It is the first film where both Elmer Fudd and Bugs are shown in their fully developed forms as hunter and tormentor, respectively; the first in which Mel Blanc uses what would become Bugs' standard voice; and the first in which Bugs uses his catchphrase, "What's up, Doc?" The film was a huge success in theaters and received an Academy Award nomination for Best Animated Short Film.
Immediately following on A Wild Hare, Bob Clampett's Patient Porky (1940) features a cameo appearance by Bugs, announcing to the audience that 750 rabbits have been born. The gag uses Bugs' Wild Hare visual design, but his goofier pre-Wild Hare voice characterization.
The second full-fledged role for the mature Bugs, Chuck Jones' Elmer's Pet Rabbit (1941), is the first to use Bugs' name on-screen: it appears in a title card, "featuring Bugs Bunny," at the start of the short (which was edited in following the success of A Wild Hare). However, Bugs' voice in this cartoon is noticeably different, and his design was slightly altered as well. After Pet Rabbit, however, subsequent Bugs appearances returned to normal: the Wild Hare visual design returned, and Mel Blanc re-used the Wild Hare voice characterization.
Hiawatha's Rabbit Hunt (1941), directed by Friz Freleng, became the second Bugs Bunny cartoon to receive an Academy Award nomination for Best Animated Short Film. The fact that it didn't win the award was later spoofed somewhat in What's Cookin' Doc? (1944), in which Bugs demands a recount (claiming to be a victim of "sa-bo-TAH-gee") after losing the Oscar to Jimmy Cagney and presents a clip from Hiawatha's Rabbit Hunt to prove his point.
By 1942, Bugs had become the number one star of Merrie Melodies. The series had originally been intended only for one-shot characters in films after several early attempts to introduce characters (Foxy, Goopy Geer and Piggy) failed under Harman–Ising (in 1937, under Leon Schlesinger, Merrie Melodies started introducing newer characters). Bugs Bunny Gets the Boid (1942) shows a slight redesign of Bugs, with less-prominent front teeth and a rounder head. The character was reworked by Robert McKimson, then an animator in Bob Clampett's unit. The redesign at first was only used in the films created by Clampett's unit, but in time it would be taken up by the other directors, with Friz Freleng and Frank Tashlin the first. When McKimson was himself promoted to director, he created yet another version, with more slanted eyes, longer teeth and a much larger mouth. He used this version until 1949 (as did Art Davis for the one Bugs Bunny film he directed) when he started using the version he had designed for Clampett. Chuck Jones would come up with his own slight modification, and the voice had slight variations between the units. Bugs also made cameos in Tex Avery's final Warner Bros. cartoon, Crazy Cruise.
Since Bugs' debut in A Wild Hare, he had appeared only in color Merrie Melodies films (making him one of the few recurring characters created for that series in the Schlesinger era prior to the full conversion to color), alongside Elmer predecessor Egghead, Inki, Sniffles, and Elmer himself. While Bugs made a cameo in Porky Pig's Feat (1943), this was his only appearance in a black-and-white Looney Tunes film. He did not star in a Looney Tunes film until that series made its complete conversion to only color cartoons beginning in 1944. Buckaroo Bugs was Bugs' first film in the Looney Tunes series, and was also the last Warner Bros. cartoon to credit Schlesinger (as he had retired and sold his studio to Warner Bros. that year).
Bugs' popularity soared during World War II because of his free and easy attitude, and he began receiving special star billing in his cartoons by 1943. By that time Warner Bros. had become the most profitable cartoon studio in the United States. In company with cartoon studios such as Disney and Famous Studios, Warners put its characters against Adolf Hitler, Benito Mussolini, and the Japanese. Bugs Bunny Nips the Nips (1944) features Bugs at odds with a group of Japanese soldiers. This cartoon has since been pulled from distribution due to its racial stereotypes of Japanese people. He also faces off against Hermann Göring and Hitler in Herr Meets Hare (1945), which introduced his well-known reference to Albuquerque as he mistakenly winds up in the Black Forest of 'Joimany' instead of Las Vegas, Nevada. Bugs also appeared in the 1942 two-minute U.S. war bonds commercial film Any Bonds Today, along with Porky and Elmer.
At the end of Super-Rabbit (1943), Bugs appears wearing a United States Marine Corps dress blue uniform. As a result, the Marine Corps made Bugs an honorary Marine Master Sergeant. From 1943 to 1946, Bugs was the official mascot of Kingman Army Airfield, Kingman, Arizona, where thousands of aerial gunners were trained during World War II. Some notable trainees included Clark Gable and Charles Bronson. Bugs also served as the mascot for 530 Squadron of the 380th Bombardment Group, 5th Air Force, U.S. Air Force, which was attached to the Royal Australian Air Force and operated out of Australia's Northern Territory from 1943 to 1945, flying B-24 Liberator bombers. Bugs riding an air delivered torpedo served as the squadron logo for Marine Torpedo/Bomber Squadron 242 in the Second World War.
In 1944, Bugs Bunny made a cameo appearance in Jasper Goes Hunting, a Puppetoons film produced by rival studio Paramount Pictures. In this cameo (animated by Robert McKimson, with Mel Blanc providing the voice), Bugs (after being threatened at gunpoint) pops out of a rabbit hole, saying his usual catchphrase; after hearing the orchestra play the wrong theme song, he realizes "Hey, I'm in the wrong picture!" and then goes back in the hole.
Although it was usually Porky Pig who brought the Looney Tunes films to a close with his stuttering, "That's all, folks!", Bugs replaced him at the end of Hare Tonic and Baseball Bugs, bursting through a drum just as Porky did, but munching on a carrot and saying in his Bronx-Brooklyn accent, "And that's the end!"
After World War II, Bugs continued to appear in numerous Warner Bros. cartoons, making his last "Golden Age" appearance in False Hare (1964). He starred in over 167 theatrical short films, most of which were directed by Friz Freleng, Robert McKimson and Chuck Jones. Freleng's Knighty Knight Bugs (1958), in which a medieval Bugs trades blows with Yosemite Sam and his fire-breathing dragon (which has a cold), won an Academy Award for Best Animated Short Film (becoming the first Bugs Bunny cartoon to win said award). Three of Jones' films — Rabbit Fire, Rabbit Seasoning, and Duck! Rabbit, Duck! — comprise what is often referred to as the "Rabbit Season/Duck Season" trilogy and are famous for originating the "historic" rivalry between Bugs and Daffy Duck. Jones' classic What's Opera, Doc? (1957), casts Bugs and Elmer Fudd in a parody of Richard Wagner's Der Ring des Nibelungen. It was deemed "culturally significant" by the United States Library of Congress and selected for preservation in the National Film Registry in 1992, becoming the first cartoon short to receive this honor.
In the fall of 1960, ABC debuted the prime-time television program The Bugs Bunny Show. This show packaged many of the post-1948 Warners cartoons with newly animated wraparounds. After two seasons, it was moved from its evening slot to reruns on Saturday mornings. The Bugs Bunny Show changed format and exact title frequently, but remained on network television for 40 years. The packaging was later completely different, with each cartoon simply presented on its own, title and all, though some clips from the new bridging material were sometimes used as filler.
Bugs did not appear in any of the post-1964 Looney Tunes and Merrie Melodies films produced by DePatie-Freleng Enterprises or Seven Arts Productions, nor did he appear in the lone Looney Tunes TV special produced by Filmation. He would not appear in new material on-screen again until Bugs and Daffy's Carnival of the Animals aired in 1976.
From the late 1970s through the 1980s, Bugs was featured in various animated specials for network television, such as Bugs Bunny's Thanksgiving Diet, Bugs Bunny's Looney Christmas Tales and Bugs Bunny's Bustin' Out All Over. Bugs also starred in several compilation films during this time, including the independently-produced documentary Bugs Bunny: Superstar (1975), which featured the vintage cartoons then owned by United Artists; as well as Warner Bros.' own efforts The Bugs Bunny/Road Runner Movie (1979), The Looney Looney Looney Bugs Bunny Movie (1981), Bugs Bunny's 3rd Movie: 1001 Rabbit Tales (1982) and Daffy Duck's Quackbusters (1988).
In the 1988 animated/live action movie Who Framed Roger Rabbit, Bugs was shown as one of the inhabitants of Toontown. However, since the film was being produced by Disney, Warner Bros. would only allow the use of their biggest star if he got an equal amount of screen time as Disney's biggest star, Mickey Mouse. Because of this, both characters are always together in frame when onscreen. Who Framed Roger Rabbit was also one of the final productions in which Mel Blanc voiced Bugs (as well as the other Looney Tunes characters) before his death in 1989.
Bugs appeared in another animated production featuring numerous characters from rival studios; the 1990 drug prevention TV special Cartoon All-Stars to the Rescue. This special is notable for being the first time that someone other than Mel Blanc voiced Bugs Bunny and Daffy Duck (both characters were voiced by Jeff Bergman for this). Bugs also made guest appearances in the early 1990s television series Tiny Toon Adventures, as the principal of Acme Looniversity and the mentor of Buster Bunny. He made further cameos in Warner Bros.' subsequent animated TV shows Taz-Mania, Animaniacs and Histeria!
Bugs returned to the silver screen in Box Office Bunny (1990). This was the first Bugs Bunny cartoon since 1964 to be released in theaters and it was created for Bugs' 50th anniversary celebration. It was followed by (Blooper) Bunny, a cartoon that was shelved from theaters, but later premiered on Cartoon Network in 1997 and has since gained a cult following among animation fans for its edgy humor.
In 1996, Bugs and the other Looney Tunes characters appeared in the live-action/animated film, Space Jam, directed by Joe Pytka. In the film, Bugs recruits Michael Jordan to help him and his friends win a basketball game against a group of aliens seeking to enslave the Tune Squad as new attractions for their homeworld's amusement park. The film also introduced the character Lola Bunny, who becomes Bugs' new love interest. The film received mixed reviews from critics, but was a box office success grossing over $230 million worldwide. The success of Space Jam led to the development of another live-action/animated film, Looney Tunes: Back in Action, released in 2003 and directed by Joe Dante. Unlike Space Jam, Back in Action was a box-office bomb, though it did receive more positive reviews from critics.
In 1997, Bugs appeared on a U.S. postage stamp, the first cartoon to be so honored, beating the iconic Mickey Mouse. The stamp is number seven on the list of the ten most popular U.S. stamps, as calculated by the number of stamps purchased but not used. The introduction of Bugs onto a stamp was controversial at the time, as it was seen as a step toward the 'commercialization' of stamp art. The postal service rejected many designs, and went with a postal-themed drawing. Avery Dennison printed the Bugs Bunny stamp sheet, which featured "a special ten-stamp design and was the first self-adhesive souvenir sheet issued by the U.S. Postal Service."
A younger version of Bugs is the main character of Baby Looney Tunes, which debuted on Cartoon Network in 2002. In the action comedy Loonatics Unleashed, his definite descendant Ace Bunny is the leader of the Loonatics team and seems to have inherited his ancestor's Brooklyn accent and comic wit.
Bugs has also appeared in numerous video games, including the Bugs Bunny's Crazy Castle series, Bugs Bunny Birthday Blowout, Bugs Bunny: Rabbit Rampage, Bugs Bunny in Double Trouble, Looney Tunes B-Ball, Looney Tunes Racing, Looney Tunes: Space Race, Bugs Bunny Lost in Time, Bugs Bunny and Taz Time Busters, Loons: The Fight for Fame and Looney Tunes: Acme Arsenal.
In 2011, Bugs Bunny and the rest of the Looney Tunes gang returned to television in the Cartoon Network sitcom, The Looney Tunes Show, with Jeff Bergman returning to voice both Bugs and Daffy Duck. The characters feature new designs by artist Jessica Borutski. Among the changes to Bugs' appearance were the simplification and enlargement of his feet, as well as a change to his fur from gray to a shade of mauve (though in the second season, his fur has been changed back to gray).
In the series, Bugs and Daffy are portrayed as best friends as opposed to their usual pairing as rivals or frenemies. At the same time, Bugs is more openly annoyed at Daffy's antics in the series (sometimes to the point of aggression), compared to his usual carefree personality from the original cartoons. Bugs and Daffy are close friends with Porky Pig in the series, although Bugs tends to be a more reliable friend to Porky than Daffy is. Bugs also dates Lola Bunny in the show, although at first he finds her to be "crazy" and a bit too talkative (he later learns to accept her personality quirks, similar to his tolerance for Daffy). Unlike the original cartoons, Bugs lives in a regular home, which he shares with Daffy, Taz (whom he treats as a pet dog) and Speedy Gonzalez, in the middle of a cul-de-sac with their neighbors Yosemite Sam, Granny and Witch Lezah.
According to the episode "Peel of Fortune," Bugs' regular income comes from having invented the Carrot Peeler and had a temporary reversal of luck when Daffy used Bugs' blueprints to make an Automated Carrot Peeler (which Daffy made incomplete due to him not including a device to keep it from becoming flammable). When Bugs learns that Daffy being unable to refund everyone's money would cause the town to repossess their house, Bugs uses his time machine invention to go back in time, pay for Daffy's sundae, and not mention to him about his Carrot Peeler. It is also in this episode that Bugs' original home (a rabbit hole) is shown.
On August 13, 2010, Warner Bros. Pictures announced that they were planning a live-action/CG-animated combo feature film based on the Looney Tunes character. Later, on September 19, 2012, it was announced that a new Looney Tunes reboot film is in development.

Bugs Bunny is characterized as being clever and capable of outsmarting anyone who antagonizes him, including Elmer Fudd, Yosemite Sam, Willoughby the Dog, Marvin the Martian, Beaky Buzzard, Daffy Duck, Porky Pig, Tasmanian Devil, Cecil Turtle, Witch Hazel, Rocky and Mugsy, Wile E. Coyote, the Crusher, Gremlin, Count Blood Count and a host of others. Bugs almost always wins these conflicts, a plot pattern which recurs in Looney Tunes films directed by Chuck Jones. Concerned that viewers would lose sympathy for an aggressive protagonist who always won, Jones arranged for Bugs to be bullied, cheated, or threatened by the antagonists while minding his own business, justifying his subsequent antics as retaliation or self-defense. He's also been known to break the fourth wall by "communicating" with the audience, either by explaining the situation (e.g. "Be with you in a minute, folks!"), describing someone to the audience (e.g. "Feisty, ain't they?"), clueing in on the story (e.g. "That happens to him all during the picture, folks."), explaining that one of his antagonists' actions have pushed him to the breaking point ("Of course you know, this means war."), admitting his own deviousness toward his antagonists ("Gee, ain't I a stinker?"), etc.
Bugs will usually try to placate the antagonist and avoid conflict, but when an antagonist pushes him too far, Bugs may address the audience and invoke his catchphrase "Of course you realize this means war!" before he retaliates, and the retaliation will be devastating. This line was taken from Groucho Marx and others in the 1933 film Duck Soup and was also used in the 1935 Marx film A Night at the Opera. Bugs would pay homage to Groucho in other ways, such as occasionally adopting his stooped walk or leering eyebrow-raising (in Hair-Raising Hare, for example) or sometimes with a direct impersonation (as in Slick Hare). Other directors, such as Friz Freleng, characterized Bugs as altruistic. When Bugs meets other successful characters (such as Cecil Turtle in Tortoise Beats Hare, or the Gremlin in Falling Hare), his overconfidence becomes a disadvantage.
Bugs' nonchalant carrot-chewing standing position, as explained by Chuck Jones, Friz Freleng, and Bob Clampett, originated in a scene in the film It Happened One Night, in which Clark Gable's character leans against a fence, eating carrots rapidly and talking with his mouth full to Claudette Colbert's character. This scene was well known while the film was popular, and viewers at the time likely recognized Bugs Bunny's behavior as satire.
The carrot-chewing scenes are generally followed by Bugs' most well-known catchphrase, "What's up, Doc?", which was written by director Tex Avery for his first Bugs Bunny film, A Wild Hare (1940). Avery explained later that it was a common expression in his native Texas and that he did not think much of the phrase. When the cartoon was first screened in theaters, the "What's up, Doc?" scene generated a tremendously positive audience reaction. As a result, the scene became a recurring element in subsequent cartoons. The phrase was sometimes modified for a situation. For example, Bugs says "What's up, dogs?" to the antagonists in A Hare Grows in Manhattan, "What's up, Duke?" to the knight in Knight-mare Hare and "What's up, prune-face?" to the aged Elmer in The Old Grey Hare. He might also greet Daffy with "What's up, Duck?" He used one variation, "What's all the hub-bub, bub?" only once, in Falling Hare. Another variation is used in Looney Tunes: Back In Action, when he greets a blaster-wielding Marvin the Martian saying "What's up, Darth?"
Several Chuck Jones films in the late 1940s and 1950s depict Bugs travelling via cross-country (and, in some cases, intercontinental) tunnel-digging, ending up in places as varied as Mexico (Bully for Bugs), the Himalayas (The Abominable Snow Rabbit) and Antarctica (Frigid Hare) all because he "shoulda taken that left toin at Albukoikee." He first utters that phrase in Herr Meets Hare (1945), when he emerges in the Black Forest, a cartoon seldom seen today due to its blatantly topical subject matter. When Hermann Göring says to Bugs, "There is no Las Vegas in 'Chermany'" and takes a potshot at Bugs, Bugs dives into his hole and says, "Joimany! Yipe!", as Bugs realizes he's behind enemy lines. The confused response to his "left toin" comment also followed a pattern. For example, when he tunnels into Scotland in My Bunny Lies over the Sea (1948), while thinking he's heading for the La Brea Tar Pits in Los Angeles, California, it provides another chance for an ethnic stereotype: "Therrre's no La Brrrea Tarrr Pits in Scotland!" (to which Bugs responds, "Uh...what's up, Mac-doc?"). A couple of late-1950s shorts of this ilk also featured Daffy Duck travelling with Bugs ("Since when is Pismo Beach inside a cave?!").
The following are the many voice actors who have voiced Bugs Bunny over the last seventy-three years:
Like Mickey Mouse for Disney, Bugs Bunny has served as the mascot for Warner Bros. and its various divisions. On December 10, 1985, Bugs became the second fictional character (after Mickey) to receive a star on the Hollywood Walk of Fame.
In 2002, TV Guide compiled a list of the 50 greatest cartoon characters of all time as part of the magazine's 50th anniversary. Bugs Bunny was given the honor of number 1. In a CNN broadcast on July 31, 2002, a TV Guide editor talked about the group that created the list. The editor also explained why Bugs pulled top billing: "His stock...has never gone down...Bugs is the best example...of the smart-aleck American comic. He not only is a great cartoon character, he's a great comedian. He was written well. He was drawn beautifully. He has thrilled and made many generations laugh. He is tops."
Dizziness is an impairment in spatial perception and stability. Because the term dizziness is imprecise, it can refer to vertigo, presyncope, disequilibrium, or a non-specific feeling such as giddiness or foolishness.
One can induce dizziness by engaging in disorientating activities such as spinning.
A stroke is the cause of isolated dizziness in 0.7% of people who present to the emergency room.
Dizziness is broken down into 4 main subtypes: vertigo (~50%), disequilibrium (less than ~15%), presyncope (less than ~15%) and lightheadedness (~10%).
Many conditions are associated with dizziness. However, the most common subcategories can be broken down as follows: 40% peripheral vestibular dysfunction, 10% central nervous system lesion, 15% psychiatric disorder, 25% presyncope/dysequilibrium, and 10% nonspecific dizziness. The medical conditions that often have dizziness as a symptom include:
Many conditions cause dizziness because multiple parts of the body are required for maintaining balance including the inner ear, eyes, muscles, skeleton, and the nervous system.
Common physiological causes of dizziness include:
About 20–30% of the population report to have experienced dizziness at some point in the previous year.
