If left untreated, rectal prolapse can lead to serious complications.

Rectal prolapse happens when a portion of or all of the rectum’s wall slides out of place.

Rectal prolapse is most common in children and older adults, particularly women. In children, it can be found with cystic fibrosis and whipworm (trichuriasis). In adults, it is usually found with constipation. It is also more common in people with autism, psychiatric disorders and intellectual disability.

The main symptom is a reddish-colored mass sticking out from the anus, especially following a bowel movement. This mass is actually the inner lining of the rectum and may bleed slightly and be uncomfortable and painful.

If untreated, rectal prolapse could lead to serious complications, such as leaking stool that gets worse or a damaged rectum.


The healthcare provider will perform a physical exam, which may include a rectal exam. Tests can help determine the underlying cause.


Call your healthcare provider if a rectal prolapse occurs. In some cases, the prolapse can be treated at home.
