In short
In mucosal prolapse, the lining of the lower rectum slides towards or through the anus. It differs from full-thickness rectal prolapse but can cause significant irritation, bleeding and difficulty emptying the bowel.
Seek emergency care if a larger prolapse becomes trapped outside the anus, very painful or dark in colour.
What happens at the examination
We review bowel function and symptoms and perform a proctological examination. Further assessment of the pelvic floor or colon may sometimes be needed before treatment.
- Assessment during straining
- Distinguishing prolapse from haemorrhoids
- Proctoscopy and/or rectoscopy when indicated
- Decision on further investigation
Treatment options
The most suitable treatment is decided after an individual medical assessment.
After treatment
After treatment you receive individual advice on stool consistency, toilet habits, activity and follow-up.
Frequently asked questions
Is mucosal prolapse the same as haemorrhoids?
No, although symptoms can be similar and both conditions can occur together.
What does mucosal prolapse feel like?
Common signs include bulging during straining, mucus, moisture, minor bleeding, leakage and a feeling of incomplete emptying.
How is it diagnosed?
Diagnosis is based on your symptoms and a proctological examination. The prolapse may need to be assessed during straining, and further tests are sometimes required.
Is surgery required?
Not always. The choice depends on the extent of prolapse and severity of symptoms.
Can rubber bands be used?
Selected smaller mucosal prolapses can sometimes be treated with rubber-band ligation. It is not suitable for everyone and is decided after examination.
Can constipation make it worse?
Yes. Hard stools and prolonged straining can contribute to symptoms.
Is mucosal prolapse dangerous?
It is often not an emergency but should be assessed when it causes bleeding, leakage or difficulty emptying. A trapped, very painful or dark-coloured prolapse requires emergency care.
Can it return after treatment?
Yes. Recurrence can occur and is influenced by factors such as constipation, straining and the extent of the prolapse.
