Uterine Prolapse -

Uterine prolapse occurs when pelvic floor muscles and ligaments stretch and weaken and no longer provide enough support for the uterus. As a result, the uterus slips down into or protrudes out of the vagina.
Uterine prolapse can occur in women of any age. But it often affects postmenopausal women who've had one or more vaginal deliveries

Symptoms -

Mild uterine prolapse generally doesn't cause signs or symptoms.
Signs and symptoms of moderate to severe uterine prolapse include:
Sensation of heaviness or pulling in your pelvis
Tissue protruding from your vagina
Urinary problems, such as urine leakage (incontinence) or urine retention
Trouble having a bowel movement
Feeling as if you're sitting on a small ball or as if something is falling out of your vagina
Sexual concerns, such as a sensation of looseness in the tone of your vaginal tissue
