The bulging, sagging or falling of pelvic organs (bladder, uterus, rectum, intestine). Prolapse develops slowly, so symptoms may be mild and vague at first, such as pain during sexual intercourse or inability to hold in a tampon. As prolapse progresses symptoms may develop into a feeling that something is protruding from the vagina, a heavy sensation in the vagina or an inability to urinate or have a bowel movement without inserting the fingers into the vagina.
