Although it remains an awkward, rarely discussed topic, pelvic organ prolapse is incredibly common. The Women's Health Initiative study found that 50-60% of women have some degree of prolapse, and 41% have a significant amount.
Prolapse occurs when one or more pelvic organs (the bladder, uterus, rectum) begin to bulge into the vagina. This happens because the muscles and connective tissues in the area weaken over time. Childbirth is a big cause, but prolapse also happens to women without children and women who had C-sections.
