The rectum which is a muscular tube of the large intestine is usually kept well supported inside the pelvic cavity. When these supports become loose Or because of constant repeated straining in the motion due to constipation, the rectum is subjected to continuous outward pressure and that causes the rectum to protrude out of the anal canal and hang out like a tube. This is usually seen in old people but we also encounter this condition in many young people.

In the early stages whenever the patient passes motion the rectum comes out of the anal Canal and after that it can either spontaneously go back inside or the patient can push it back with his fingers.

As time progresses and as the disease gets severe, the rectum comes out and refuses to go back inside and this becomes a major problem.
