- Loose muscles of the anal sphincter
- An abnormally long colon
- Downward movement of the abdominal cavity between the rectum and uterus

Symptoms
The main symptom is a reddish-colored mass that sticks out from the opening of the anus, especially after a bowel movement. This reddish mass is actually the inner lining of the rectum. It may bleed slightly and can be uncomfortable and painful.
Exams and Tests
Your health care provider will perform a physical exam, which will include a rectal exam. To check for prolapse, the provider may ask the person to bear down while sitting on a toilet.

Treatment
Contact your provider if a rectal prolapse occurs.
In some cases, the prolapse can be treated at home. Follow your provider's instructions on how to do this. The rectum must be pushed back inside manually. A soft, warm, wet cloth is used to apply gentle pressure to the mass to push it back through the anal opening. The person should lie on one side in a knee-chest position before applying pressure. This position allows gravity to help put the rectum back into position.
Immediate surgery is rarely needed. In children, treating the cause often solves the problem. For example, if the cause is straining because of dry stools, laxatives may help. If the prolapse continues, surgery may be needed.
In adults, the only cure for rectal prolapse is a procedure that repairs the weakened anal sphincter and pelvic muscles.
Procedure
