[Rectal prolapse].

What is rectal prolapse? Rectal prolapse is a condition in which the rectum (the lower end of the colon, located just above the anus) becomes stretched out and protrudes out of the anus. Weakness of the anal sphincter muscle is often associated with rectal prolapse at this stage, resulting in leakage of stool or mucus. While the condition occurs in both sexes, it is much more common in women than men.
