Belching and farting are considered to be caused by dietary factors, and may also be caused by indigestion, gastrointestinal dysfunction and other disease factors. 1. Dietary factors: eating some gas-producing foods, such as soy products, sweet potatoes, etc., these foods will be decomposed in the stomach to produce gas, resulting in belching and farting. 2. Indigestion: When indigestion occurs, gastrointestinal peristalsis slows down, and food accumulates in the stomach to ferment and produce gas, leading to belching and farting. 3. Gastrointestinal dysfunction: the patient’s gastrointestinal function is affected by the disease, belching and farting will increase, accompanied by a series of symptoms such as diarrhea and abdominal pain. When belching and farting occur, it is recommended to go to the hospital and ask the doctor to make a judgment, clarify the cause of the disease and actively treat it.
