Farting can be caused by improper diet, intestinal diseases, gastrointestinal dysfunction and so on. 1. Improper diet: When taking too much cold food or gas-producing food such as potatoes and sweet potatoes, a large amount of gas accumulates in the intestinal tract, and the symptom of farting may occur. 2. Intestinal diseases: when there are constipation, enteritis, intestinal obstruction and other intestinal diseases, a large amount of gas accumulates under the action of intestinal bacteria, and the symptom of farting may also occur. 3. Gastrointestinal dysfunction: when there are improper diet, lack of sleep, mental stress and other triggers, it may lead to gastrointestinal dysfunction, abnormal intestinal peristalsis, resulting in the accumulation of gas and farting symptoms. The symptoms of gas and farts alone cannot determine the cause, and further examination and treatment in the hospital is required.
