Being pregnant and giving birth are the most common causes of weakening of the pelvic floor, particularly if your baby was large, you had an assisted birth (forceps/ ventouse) or your labour was prolonged. The more births a woman has, the more likely she is to develop a prolapse in later life; however, you can still get a prolapse even if you haven’t given birth. Performing pelvic floor exercises is very important after childbirth but may not prevent prolapse from occurring.
