Gastric bloating, burping and flatulence are mostly considered to be related to functional dyspepsia, chronic gastritis and intestinal flora imbalance. 1. Functional dyspepsia: it is mostly seen in improper diet, such as overeating or overeating greasy food, which leads to decreased gastrointestinal function, slower peristalsis, and food stays in the gastrointestinal tract for a long time, generating a large amount of gas, which causes related symptoms. 2. Chronic gastritis: chronic gastritis can appear gastrointestinal dysfunction, resulting in long-term retention of food in the stomach, often causing symptoms of flatulence, burping and increased exhaust. 3. Intestinal flora imbalance: mainly the decrease of beneficial bacteria and increase of harmful bacteria in the intestinal tract, resulting in the production of a large amount of gas, which leads to gastric bloating, sometimes accompanied by burping and excessive exhaust symptoms. The above symptoms may also be caused by other reasons. If the symptoms continue to be unrelieved, it is recommended to consult a doctor in a timely manner to clarify the cause of the disease under the guidance of a professional physician.
