The post-operative fistula is directly related to the patient’s diet and exercise, because the post-operative patient has less exercise, intestinal peristalsis is relatively poor, and the diet is generally based on light and liquid food, so it is difficult to shape the stool. The actual fact is that you will be able to get a lot more than just a few of these. However, if you have diarrhea or an increase in the number of stools after anal fistula surgery, you should choose medication to regulate and promote the recovery of intestinal function. You can usually choose drugs such as Ginseng and Atractylodis Macrocephalae, Mei Changan, and Rectify Intestine to help promote the recovery of intestinal function. At the same time eat more foods rich in fiber, such as celery, sweet potatoes, etc., and appropriate walking on the ground to promote bowel movement, but also to help the formation of stools.
