Pelvic Floor Disorders

The pelvic floor is a group of muscles and other tissues that form a sling or hammock across the pelvis. In women, it holds the uterus, bladder, bowel, and other pelvic organs in place so that they can work properly. The pelvic floor can become weak or be injured. The main causes are pregnancy and childbirth. Other causes include being overweight, radiation treatment, surgery, and getting older.
