Pelvic floor dysfunction is the inability to control the muscles of your pelvic floor.Your pelvic floor is the group of muscles and ligaments in your pelvic region. The pelvic floor acts like a sling to support the organs in your pelvis — including the bladder, rectum, and uterus or prostate. Contracting and relaxing these muscles allows you to control your bowel movements, urination, and, for women particularly, sexual intercourse.Pelvic floor dysfunction forces you to contract your muscles rather than relax them. As a result, you may experience difficulty having a bowel movement.If left untreated, pelvic floor dysfunction can lead to discomfort, long-term colon damage, or infection.
