Weakness in the pelvic muscle floor can lead to prolapse. Symptoms include vaginal bulging or pressure, difficulty emptying the bladder completely or experiencing frequent urinary tract infections, and difficulty passing bowel movements (sometimes requiring pressure in the vagina from a finger in order to pass).
Prolapse treatments can vary from special pelvic exercises or physical therapy, to pessary use or surgical reconstruction.
