Rectal prolapse

In a rectal prolapse, part or all of the wall of the rectum slides out of place and sticks out of the anus. It may be a:

• Complete prolapse. The entire wall of the rectum slides out of place. At first, it may slip out of the anus only during bowel movements. Over time, this may occur when you stand or walk. And in some cases, the tissue may bulge out of the anus all the time.
• Partial prolapse. The lining (mucous membrane) of the rectum slides out of place. It may slip out of the anus when you strain to have a bowel movement.

Rectal prolapse is most common in older female adults. It sometimes occurs in young children.

The first symptoms of rectal prolapse may be:

• Leaking of stool from the anus (fecal incontinence).
• Leaking of mucus or blood from the anus (wet anus).

Other symptoms may include:

• A feeling of having full bowels and an urgent need to have a bowel movement.
• Passage of many very small stools.
• The feeling of not being able to empty the bowels completely.
• Anal pain, itching, irritation, and bleeding.
• Bright red tissue that sticks out of the anus.

Your doctor will ask about your symptoms and medical history and do a physical exam. This may include checking the rectum for loose tissue and checking how strongly the anal sphincter contracts.

You may need tests to rule out other conditions. For example, you may need a colonoscopy or a barium enema. These may be done to look for tumors, sores (ulcers), or abnormal narrow areas in the large intestine.

If a rectal prolapse doesn't improve with self-care, you may need surgery. Doctors may attach the rectum to the muscles of the pelvic floor or the lower end of the spine (sacrum). In some cases, they may also remove a section of the large intestine.

• Avoid constipation. Drink plenty of water, and eat fruits, vegetables, and other foods that contain fiber. Changes in diet often are enough to improve or reverse a partial prolapse.
• Try Kegel exercises to help strengthen the muscles of the pelvic area. You do Kegel exercises by tightening your muscles as if you were holding back urine or gas.
• Don't strain during a bowel movement. Use a stool softener if you need to.
• If it happens again, and if your doctor says it's okay, you can push the prolapse back into place.
