A bowel or rectal prolapse occurs when the rectum drops down into the anus. Unlike vaginal prolapse, which is relatively common, rectal prolapse is less common and affects about 2.5 out of every 100,000 people.
Symptoms differ from a bladder prolapse but have similar features, including bowel incontinence, constipation, diarrhea, or both, reddish-colored mass sticking out of the anus, passing mucus or blood from the rectum and feeling that the rectum is not empty after a bowel movement
