Generally speaking, 1-2 bowel movements a day is the most beneficial to health. Whether three bowel movements a day is normal is related to each individual’s specific situation. If there is no significant increase in stool volume and no abnormal stool properties, this is normal. If there is an increase in the volume of stool compared to the previous one, but there is no abnormality in the stool properties, it may be caused by consuming more food rich in dietary fiber. If the stool is thin or even watery, it is more likely to be caused by acute gastroenteritis or irritable bowel syndrome. If the condition of three bowel movements per day lasts for 3 weeks or recurring for a long time, it is chronic diarrhea, and it is recommended to visit relevant departments such as the gastroenterology department of the hospital to clarify the cause so as not to delay the condition. In life, you should change bad bowel habits, focus on defecation and do not play with your cell phone. Because playing with cell phones may lead to prolonged defecation until the legs are numb, which in turn affects normal defecation and may lead to constipation, etc.
