The desire to have a bowel movement after exercise is associated with increased bowel movement speed and irritable bowel syndrome. Exercise has many benefits for human health, not only to improve the body’s immunity and resistance to disease, but also to anti-aging. When the intestinal tract moves faster, the contents of the intestines will be excreted more easily, so the feeling of wanting to defecate will occur. Some people have irritable bowel syndrome, and these people should try to avoid too strenuous exercise, otherwise the exercise will lead to a stress response in the intestine, and peristalsis will be hyperactive. Not only will there be a desire to defecate, but some of them will also have diarrhea and abdominal distension. The desire to defecate after exercise is normal as long as the nature of the stool is normal and there are no other abdominal discomfort symptoms.
