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.
Abdominal distension occurs when substances, such as air (gas) or fluid, accumulate in the abdomen causing its outward expansion beyond the normal girth of the stomach and waist. It is typically a symptom of an underlying disease or dysfunction in the body, rather than an illness in its own right. People suffering from this condition often describe it as "feeling bloated." Sufferers often experience a sensation of fullness, abdominal pressure and possibly nausea, pain or cramping. In the most extreme cases, upward pressure on the diaphram and lungs can also cause shortness of breath. Through a variety of causes (see below), bloating is most commonly due to buildup of gas in the stomach, small intestine or colon. The pressure sensation is often relieved, or at least lessened, by burping (belching) or passing gas (flatulence). Medications that settle gas in the stomach and intestines are also commonly used to treat the discomfort and lessen the abdominal distension.
Experts believe that a major cause of abnormal bloating is excessive eating and sleep swallowing, known as aerophagia. Other causes of bloating are irritable bowel syndrome, diabetes, functional dyspepsia or transient constipation. In rare cases, bloating may occur in individuals who have milk intolerance (lactose intolerance), parasite infections like giardia, food poisoning (bacteria), celiac disease, severe peptic ulcer disease, bowel obstruction or after certain types of abdominal surgery.
The stomach is an important organ in the body. It plays a vital role in digestion of foods, releases various enzymes and also protects the lower intestine from harmful organisms. The stomach connects to the esophagus above and to the small intestine below. It is intricately related to the pancreas, spleen and liver. The stomach does vary in size but its J shape is constant. The stomach lies in the upper part of the abdomen just below the left rib cage.
Gastropathy is a general term used for stomach disease. Examples including the name include portal hypertensive gastropathy and Ménétrier's disease, also known as "hyperplastic hypersecretory gastropathy". However, there are many other stomach diseases that don't include the word "gastropathy" such as gastric or peptic ulcer disease, gastroparesis, and dyspepsia.
