If a person maintains a bowel movement frequency of 3 times a day for a long period of time and there are no other physical abnormalities, it is usually normal and there is no need to worry. However, if a person suddenly has 3 or more bowel movements a day in a short period of time, this should be taken seriously. Adults who have 1-2 bowel movements a day or 1 bowel movement every 2 days are usually considered normal physiological phenomena. If a person has 3 bowel movements per day for a long period of time, and the shape of the stool is normal, not accompanied by wasting, anemia and other manifestations, it is usually due to rapid intestinal movement, there is generally no organic pathology. If the bowel movement is suddenly greater than 3 times a day in a short period of time, there is a possibility of enteritis. If the bowel movement is accompanied by pain, incomplete symptoms, or even pus and blood, you need to go to the Department of Gastroenterology as soon as possible, and perform colonoscopy and other related examinations to clarify the diagnosis. In addition, patients should pay attention to drink more water, eat a balanced diet, eat less spicy and stimulating and fried foods, and pay attention to dietary hygiene to relieve the symptoms of diarrhea.
