There is 100- 150 ml gas in the gastrointestinal tract of normal people. If there is too much gas in the gastrointestinal tract, abdominal distension will occur. Abdominal distension is mostly caused by stagnation of food retention, dampness blocking the spleen and stomach, qi stagnation of liver and stomach, and qi deficiency of spleen and stomach.

Chronic gastritis, gastric ulcer, gastroptosis, gastric dilatation, intestinal obstruction, gastric neurosis, acute and chronic hepatitis, cholecystitis, gallstones, pancreatitis and other gastrointestinal diseases can all cause abdominal distension. Cardiovascular diseases such as heart failure, mesenteric arteriosclerosis, mesenteric artery infarction, new communication and arrhythmia can also cause abdominal distension reflexively.
