Uterine prolapse is when the uterus descends towards or through the opening of the vagina. Symptoms may include vaginal fullness, pain with sex, trouble urinating, urinary incontinence, and constipation. Often it gets worse over time. Low back pain and vaginal bleeding may also occur. Risk factors include pregnancy, childbirth, obesity, constipation, and chronic coughing. Diagnosis is based on examination. It is a form of pelvic organ prolapse, together with bladder prolapse, large bowel prolapse, and small bowel prolapse.
