Epigastric flatulence may be caused by dietary factors, or it may be caused by functional dyspepsia, chronic gastritis and other diseases. 1. Dietary factors: Eating a large amount of gas-producing food at one time, such as beans, sweet potatoes, etc., or eating too quickly and taking in too much air, can cause the symptoms of epigastric flatulence. 2. Functional dyspepsia: It can cause gastrointestinal function to weaken, resulting in food accumulating in the digestive tract after eating, leading to the symptoms of epigastric flatulence. 3. Chronic gastritis: most patients with chronic gastritis have no obvious symptoms, with indigestion, flatulence, hiccups and so on as the main manifestations, which may be caused by stomach inflammation, gastrointestinal insufficiency of power, dysfunction of bacterial flora and so on. You can take digestive enzyme preparations such as compound digestive enzyme tablets to promote gastrointestinal digestive function; you can also take gastric mucous membrane protective agents such as aluminum sulfate. When symptoms of epigastric flatulence occur, it is recommended to go to the hospital after excluding dietary factors, and ask the doctor to make a judgment to clarify the cause of the disease.
