What are the symptoms of rectal prolapse?
- The first thing you will notice is a lump sticking out of your back passage (anus). In the early stages this will only appear after you've had a poo or strained to pass a motion. It tends to disappear when you stand up.
- Later on, you may notice the lump in other circumstances that involve straining, like coughing or sneezing.
- Eventually, the lump may be noticeable most of the time and interfere with day-to-day activities such as walking.
- You may have to push the lump back with your hand.
- A doctor examining the prolapse will see a lump sticking out which has concentric rings around it. An ulcer on the prolapse may also be seen.

- You may notice pain, constipation and bleeding from the last part of your bowel (the rectum).
- The muscles around the anus (anal sphincter) may become weak, allowing a little bit of poo to escape (faecal incontinence). This can also happen with slime (mucus) produced by the bowel wall.
Who gets rectal prolapse?
No-one knows how common rectal prolapse is because people often have it without reporting it to their doctor. However, it is known to happen most frequently in the elderly. Women seem to be more prone to it than men.
It is occasionally seen in children, especially from the ages of 1 to 3 years.
What causes rectal prolapse?
- Anything that increases the pressure inside your tummy (abdomen) can make you more likely to develop a rectal prolapse. This can include:
- Straining to pass urine due to a swollen prostate gland.
- Persistent cough.
- Damage to the back passage (anus) or pelvis from previous surgery.
- Damage to the muscle on the floor of the pelvis.
- Infections of the bowel with certain types of microbes called parasites (such as amoebiasis and schistosomiasis).
- Diseases of the nervous system such as multiple sclerosis.
- Damage to the nerves from back surgery, a slipped disc, or an accident injuring the pelvic nerves.
- Mental health conditions associated with constipation, such as:
- Anxiety (as in irritable bowel syndrome).
- A side-effect of medicines used to treat psychiatric disorders.
In children, rectal prolapse can occur in:
- Cystic fibrosis.
- Ehlers-Danlos syndrome.
- Hirschsprung's disease (a rare condition that can cause poo to become stuck in the bowel).
- Malnutrition (not having enough food, not eating the right food, or not being able to absorb the nourishment from food).
- Rectal polyps.

Prolapse of the bladder or womb (uterus) doesn't cause rectal prolapse but is sometimes associated with it.
