Characterization of Pelvic Organ Prolapse

Pelvic organ prolapse | The BMJ

Pelvic organ prolapse happens when the muscles and tissues supporting the pelvic organs (the uterus, bladder, or rectum) become weak or loose. This allows one or more of the pelvic organs to drop or press into or out of the vagina. Many women are embarrassed to talk to their doctor about their symptoms or think that their symptoms are normal. But pelvic organ prolapse is treatable.
