A prolapse of the uterus or vagina is when one or both of these organs is displaced due to weakening or stretching of their supporting tissues (which might happen during childbirth).
In a uterine prolapse, the uterus moves down into the vagina.
In the type of vaginal prolapse called a cystocele, the bladder presses inward against the front vaginal wall. In the other main type of vaginal prolapse, a rectocele, the rectum bulges against the back vaginal wall.
Symptoms may include a feeling of fullness in the vagina, a bulge protruding into or out of the vagina, difficulty passing urine or feces, frequent urination, and discomfort during sex.
Mild cases often require only measures such as pelvic floor exercises to prevent the condition from worsening.
Other treatments include a vaginal pessary to keep the prolapsed organ in place or, occasionally, surgery.
