Upright posture

Animals that walk on four legs only rarely get posterior prolapse. The upright weight placed on a woman's pelvic floor is the main reason women experience posterior prolapse.

Increased pelvic floor pressure

Other conditions and activities that increase the pressure already on the pelvic floor and can cause or contribute to posterior prolapse include:

  • Chronic constipation or straining with bowel movements
  • Chronic cough or bronchitis
  • Repeated heavy lifting
  • Being overweight or obese

Pregnancy and childbirth

Pregnancy and childbirth increase the risk of posterior prolapse. This is because the muscles, ligaments and fascia that hold and support your vagina become stretched and weakened during pregnancy, labor and delivery. As a result, the more pregnancies you have, the greater your chance of developing posterior prolapse.

Not everyone who has had a baby develops posterior prolapse. Some women have very strong supporting muscles, ligaments and fascia in the pelvis and never have a problem. Women who have only had cesarean deliveries are less likely to develop posterior prolapse. But even if you haven't had children, you can develop posterior prolapse.
