Risk factorsBy Mayo Clinic staff
The following factors may increase your risk of experiencing posterior prolapse:
- Genetics. Some women are born with weaker connective tissues in their pelvic area, making them naturally more likely to develop posterior prolapse. Others are born with stronger connective tissues.
- Childbirth. If you have vaginally delivered multiple children, you have a higher risk of developing posterior prolapse. If you've had tears in the tissue between the vaginal opening and anus (perineal tears) and incisions that extend the opening of the vagina (episiotomies) during childbirth, you may also be at higher risk.
- Aging. Your risk of posterior prolapse increases as you age because you naturally lose muscle mass, elasticity and nerve function as you grow older, causing muscles to stretch or weaken.
- Obesity. A high body mass index is linked to an increased risk of posterior prolapse. This is likely due to the chronic stress that excess body weight places on pelvic floor tissues.
