Farting all the time when going to the toilet may be caused by improper diet, intestinal flora imbalance, intestinal bacterial infection and so on. 1. Improper diet: patients keep farting when going to the toilet, which may be caused by eating too much gas-producing food, such as chestnut, radish, pumpkin, cabbage, sweet potato, yam and so on. 2. Intestinal flora imbalance: the change of intestinal flora activity or the change of flora composition of the patient can lead to intestinal flora imbalance, which may result in nausea, vomiting, abdominal distension, and constant flatulence when going to the toilet. 3. Intestinal bacterial infection: If the intestinal tract is infected by bacteria, it will constantly stimulate the mucous membrane of gastrointestinal tract, leading to symptoms such as diarrhea, nausea, abdominal distension and flatulence. It is recommended that patients should go to the hospital in time when they have symptoms of frequent flatulence, so as to clarify the cause of the disease under the guidance of professional physicians.
