Farting is exhausting, and exhausting all the time at night may be caused by dietary factors, indigestion, intestinal flora imbalance, gastroenteritis and other reasons. 1. Dietary factors: when you eat more starchy and protein foods at dinner, such as sweet potatoes, potatoes, soy products, etc., more gas will be produced after decomposition, which can lead to the phenomenon of exhaust at night. 2. Indigestion: Gastrointestinal peristalsis is slow, the food in the stomach can’t be emptied in time, and it stays in the gastrointestinal tract for too long, which increases the amount of gas production, and also causes the symptom of exhausting all the time at night, and it may be accompanied by abdominal distension, nausea and other symptoms. 3. Intestinal flora imbalance: Harmful bacteria multiply more, fermentation produces a large amount of gas, which can also cause the phenomenon of exhaust at night. 4. Gastroenteritis: gastrointestinal tract mucosa infected by pathogenic bacteria can also cause gas all the time, abdominal pain, bowel sounds and other symptoms. It is recommended to consult a doctor in time to find out the cause of the disease under the guidance of a professional physician and follow the doctor’s instructions.
