Much like a hammock, muscles and ligaments keep the pelvic organs (bladder, uterus, and rectum) in place. During childbirth, these muscles and ligaments can get stretched or can tear, becoming too weak to hold the organs in place.
When this occurs the bottom of the uterus or the floor of the bladder, or both, can sag through the muscles and ligaments and impact the vagina. In severe cases the uterus or bladder can fall far enough that a bulge can appear at the vagina’s opening or even protrude from the vaginal opening.
Every woman is different so the best treatment option will be determined between you and Dr. Boatwright.
