Recently always fart, mainly consider gastroenteritis, irritable bowel syndrome, intestinal obstruction and other causes. 1. Gastroenteritis: when patients eat unclean, indigestible, too cold, too spicy and other irritating food, it will lead to intestinal wall mucosa damage, gastrointestinal function peristaltic disorder, thus intestinal flatulence, accompanied by severe abdominal pain, diarrhea, always farting. 2. Irritable bowel syndrome: it is mostly related to the patient’s emotion, spirit and stress, which causes intestinal flora imbalance, intestinal peristalsis disorder and always farting. 3. Intestinal obstruction: when patients have incomplete intestinal obstruction due to dynamic and mechanical reasons, the lower part of the intestinal tract does not circulate smoothly, which will cause a large amount of gas to be produced, thus always farting occurs. In addition, there may be other reasons for farting all the time, so we suggest that patients go to the hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or therapy under the guidance of the doctor.
