It is not normal to have 3 to 4 bowel movements a day. The normal bowel movement for the average adult is 1 to 2 times. There are many reasons for increased bowel movements, such as functional dyspepsia, irritable bowel syndrome, intestinal tumors, and dietary changes. 1. Functional dyspepsia: Functional dyspepsia may lead to an increase in the number of bowel movements. The human digestive system is a complex system with a clear division of labor, and functional dyspepsia results in abnormal absorption in the intestines, which leads to faster defecation, and the number of bowel movements will increase accordingly. 2. Irritable bowel syndrome: patients with irritable bowel syndrome are prone to have the desire to defecate in case of nervousness, stress, anxiety, etc. If the patients are in such a state of mind for a long time, it is easy to cause an increase in the number of bowel movements. 3. Intestinal tumors: malignant tumors of the intestines and intestinal polyps may also cause increased bowel movements. 4. Dietary changes: if you eat food rich in dietary fiber or greasy food within a short period of time, you may have more bowel movements during this period of time. If you have bowel movements 3 to 4 times a day, you should go to a regular hospital to see a specialist to find out the cause and follow the doctor’s instructions for symptomatic treatment.
