The old toilet bowel movement refers to the high frequency of bowel movement, which may be caused by dietary factors, abdominal cold, intestinal flora imbalance, ulcerative colitis and so on. 1. Dietary factors: If you eat more dietary fiber food, it will increase the peristalsis of the intestinal tract, resulting in more frequent bowel movements. 2. Abdominal cold: it may be due to the fact that you don’t cover up well when you sleep at night, which leads to the increase of intestinal peristalsis, and it is easy to have a high frequency of bowel movements. 3. Intestinal flora imbalance: mainly the decrease of beneficial bacteria in the intestinal tract and the increase of harmful bacteria, which can easily lead to the invasion of viruses and bacteria into the intestinal tract, and the acceleration of intestinal peristalsis, which can lead to frequent bowel movements. 4. Ulcerative colitis: the etiology is not clear, but it is considered to be related to genetic factors, environmental factors, immune factors, etc., in the active phase of the disease will often cause frequent bowel movements, the less severe may have 2-3 bowel movements per day, and the more severe may have more than 10 bowel movements. Frequent bowel movements may also be caused by other reasons, if the symptoms persist, you should go to the hospital in time to find out the cause and then targeted treatment.
