Slight prolapse is pretty common (dribble a bit when you sneeze or laugh too hard) in post-childbirth years, especially if you have multiple vaginal births. I don’t know if it’s common in older women who haven’t had children, though.
You can still have sex, if it isn’t painful for you. My doctor assured me that nothing would pull my bladder out…it would be pushed out from the inside.
There are a couple of things that might help: Pelvic floor physical therapy (not to be confused with kegels), a pessary, and surgery (using stitches, mesh or your own internal tissues to hold it up).
I had a surgical repair done w/ stitches at the time of my hysterectomy, but I have a connective tissue disorder and the stitches ripped out nearly immediately. Now I have severe prolapse, ugh. Back to the drawing board, for me!
