Causes

Posterior vaginal prolapse results from pressure on the pelvic floor. Causes of increased pelvic floor pressure include:

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

Pregnancy and childbirth

The muscles, ligaments and connective tissue that support your vagina become stretched and weakened during pregnancy, labor and delivery. The more pregnancies you have, the greater your chance of developing posterior vaginal prolapse.

Women who have had only cesarean deliveries are less likely to develop posterior vaginal prolapse, but still may.
