It is normal for a normal person to have 1-2 bowel movements per day or 1-2 bowel movements per day. The regularity of human bowel movement is obviously related to diet, surrounding environment, mental factors, environmental factors, age factors and medications. After eating, food is decomposed, digested and absorbed in the gastrointestinal tract to form feces, and the speed of its discharge mainly depends on the speed of intestinal peristalsis, and the speed of intestinal peristalsis is not only related to the above factors, but also has a large individual difference. Therefore, in general, defecation is 1-2 times a day or 1-2 times a day. If patients have abnormal bowel movements, such as less than 3 times a week, they should improve their diet and lifestyle habits and be given laxative medication if necessary; if the number of bowel movements increases or the stool is thin and accompanied by abdominal discomfort, diarrhea should be considered and should be treated actively.
