Physiological reasons: mainly improper diet, a large number of dietary gas-producing foods such as beans, potatoes, groundnuts, potatoes, soybeans, etc., these foods can produce a large amount of gas in the gastrointestinal tract, resulting in gastrointestinal flatulence, it is recommended that you do not take a large number of such foods at one time, and appropriate physical exercise to promote gastrointestinal peristalsis and reduce the time that the gas in the intestinal tract stays. 2. Pathological causes: the main reason is digestive dysfunction and gastrointestinal power insufficiency. Gastrointestinal power due to significantly weakened food stays in the gastrointestinal tract for a long time, generating a large amount of gas leading to flatulence. You can choose to promote gastric power drugs (such as domperidone, gastric elimination tablets, etc.), usually eat small meals, drink less carbonated beverages, do not eat too sweet, too acidic food.
