Pregnancy can increase a person's risk of bladder prolapse. Some experts indicate that it may be due to the pressure the developing fetus places on the pelvic floor. An older study from 2014 also indicated that vaginal delivery and other potential factors increase a person's risk of prolapsing from pregnancy.
In either case, a person may experience a vaginal bulge, incontinence, leaking, or other symptoms. People should discuss these with a doctor to receive a diagnosis and treatment.
