Your pelvis is the lower part of your belly, below your navel and between your hips. There are a lot of organs in this tight space -- your bladder, cervix, intestines, rectum, urethra, uterus, and vagina.

Sometimes, the muscles and other kinds of tissue that hold everything in place get stretched out, weak, or torn. When that happens, some of your body parts can drop down below where they’re supposed to be. Some of your body tissue can stick out of your vagina. This is called prolapse. It can affect all the organs in your pelvis.

Nearly half of all women between ages 50 and 79 have at least a little bit of pelvic organ prolapse (POP). It doesn’t always cause symptoms, so you could actually have it and not know it. Men can get POP, too, if their bladders or rectums drop down.
