Low bowel movement and feeling of uncleanliness are caused by constipation, rectal polyps, and chronic enteritis. Constipation is not only difficult to defecate, but also the stool is overly absorbed in the intestine for a long time, and the volume of stool is relatively small. People with constipation have slow bowel movements and are unable to remove all the stool from their intestines, so they feel like they can’t get rid of it. When polyps are present in the rectum, they not only affect the function of the colon, but also cause local irritation, and many people have a feeling of urgency and heaviness. The bowel movement is caused by polyp irritation and is not related to the dose of feces, so the volume of bowel movement is less. In some people, there is chronic inflammation in the intestinal system, and the intestine will move faster because of the inflammation, and after the feces is discharged, new feces will be produced after a while, thus causing the patient to feel unclean.
