If it is caused by physiological reasons, intestinal inflammation, cold, etc., it may promote defecation, and if it is the early stage of intestinal obstruction, it may not promote defecation. 1. Physiological reasons: Physiological increase in gastrointestinal peristalsis caused by heavy exercise, taking too much celery, leeks, dragon fruits, bananas and other vegetables and fruits will generally promote defecation. 2. Enteritis, cold and other reasons: peristalsis is the wave-like contraction of the intestines and stomach. Under normal circumstances, when taking coarse, indigestible food with high fiber content or catching a cold, it may lead to accelerated gastrointestinal peristalsis, which shortens the time for food to pass through the small intestine and the large intestine until it is excreted from the body, so accelerated gastrointestinal peristalsis may promote bowel movement. 3. Early stage of intestinal obstruction: intestinal tumors, polyps and other causes of intestinal obstruction in the early stage, the passage of stool discharge is blocked, even if the gastrointestinal peristalsis accelerated stool can not be discharged, so at this time, gastrointestinal peristalsis accelerated can not promote defecation. So from the gastrointestinal peristalsis alone can not judge whether to promote defecation, but also need to further check the colonoscopy, abdominal ultrasound and other projects to find the cause.
