Holistic health (or holistic medicine) is a diverse field of alternative medicine in which the "whole person" is focused on, not just the malady itself.
The holistic concept in medical practice, which is distinct from the concept in the alternative medicine, upholds that all aspects of people's needs including psychological, physical and social should be taken into account and seen as a whole. A 2007 study said the concept was alive and well in general medicine in Sweden.
Gastrointestinal cancer refers to malignant conditions of the gastrointestinal tract (GI tract) and accessory organs of digestion, including the esophagus, stomach, biliary system, pancreas, small intestine, large intestine, rectum and anus. The symptoms relate to the organ affected and can include obstruction (leading to difficulty swallowing or defecating), abnormal bleeding or other associated problems. The diagnosis often requires endoscopy, followed by biopsy of suspicious tissue. The treatment depends on the location of the tumor, as well as the type of cancer cell and whether it has invaded other tissues or spread elsewhere. These factors also determine the prognosis.
Overall, the GI tract and the accessory organs of digestion (pancreas, liver, gall bladder) are responsible for more cancers and more deaths from cancer than any other system in the body. There is significant geographic variation in the rates of different gastrointestinal cancers.
Stomach cancer, or gastric cancer, refers to cancer arising from any part of the stomach. Stomach cancer causes about 800,000 deaths worldwide per year. Prognosis is poor (5-year survival <5 to 15%) because most patients present with advanced disease.
Competitive eating, or speed eating, is a sport in which participants compete against each other to consume large quantities of food in a short time period. Contests are typically eight to 10 minutes long, and usually less than 15 minutes in length, with the person consuming the most food being declared the winner. Competitive eating is most popular in the United States, Canada, and Japan, where organized professional eating contests often offer prizes, including cash. Competitive eaters are sometimes known as "gurgitators," a word coined by Major League Eating.
Science of drugs including their origin, composition, pharmacokinetics,
pharmacodynamics, therapeutic use, and toxicology.
Pharmacology (from Greek φάρμακον, pharmakon, "poison" in classic Greek; "drug" in modern Greek; and -λογία, -logia "study of", "knowledge of") is the branch of medicine and biology concerned with the study of drug action, where a drug can be broadly defined as any man-made, natural, or endogenous (within the body) molecule which exerts a biochemical and/or physiological effect on the cell, tissue, organ, or organism. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals.
