Increased pressure on the pelvic floor is the main reason for any form of pelvic organ prolapse. Conditions and activities that can cause or contribute to small bowel prolapse or other types of prolapse include:
- Pregnancy and childbirth
- Chronic constipation or straining with bowel movements
- Chronic cough or bronchitis
- Repeated heavy lifting
- Being overweight or obese
Pregnancy and childbirth
Pregnancy and childbirth are the most common causes of pelvic organ prolapse. The muscles, ligaments and fascia that hold and support your vagina stretch and weaken during pregnancy, labor and delivery. Not everyone who has had a baby develops pelvic organ prolapse. Some women have very strong supporting muscles, ligaments and fascia in the pelvis and never have a problem.
