Involuntary urination is a frequent issue affecting obese women because excess weight can weaken pelvic muscles. Studies have shown that bariatric surgery can help to reverse the issue in the large majority of cases.
Bariatric surgery has been found to improve urinary stress incontinence. Less weight is placed on the bladder, and other physical changes take place to improve this condition.
A 2000 study of 500 patients showed 97% resolution of urinary stress incontinence in patients after gastric bypass surgery.
