Bladder Prolapse Causes
Prolapse can develop for a variety of reasons, but the most significant factor is stress on this supportive "hammock" during childbirth. Women who have multiple pregnancies or deliver vaginally are at higher risk. Other factors that can lead to prolapse include: heavy lifting, chronic coughing (or other lung problems), constipation, frequently straining to pass stool, obesity, menopause (when estrogen levels start to drop) and previous pelvic surgery.
