Fast and slow intestinal peristalsis can be judged by the presence or absence of abdominal pain, diarrhea, constipation, dyspepsia and other symptoms, but also through the digestive tract imaging and other tests to determine. 1. Fast intestinal peristalsis: food in the intestinal lumen is not fully digested and absorbed, diarrhea, abdominal pain and other uncomfortable symptoms will occur. Slow peristalsis will lead to slow absorption and digestion of food, abdominal pain, bloating, indigestion, constipation, nausea, vomiting, and even intestinal obstruction. 2. Total gastrointestinal imaging: the discharge time of barium meal is controlled by the speed of intestinal peristalsis. If the intestinal peristalsis is slow, the barium meal can be discharged in 7-8 hours; if the intestinal peristalsis is fast, the barium meal can be discharged in more than 2-3 hours. If the above symptoms are not relieved, or accompanied by other symptoms, you should go to the hospital in a timely manner, to clarify the cause and then give targeted treatment.
