Can Weight Loss Surgery Ease Urinary Incontinence?
Nearly two-thirds of women had significant improvement of their symptoms, researchers report

WEDNESDAY, July 23, 2014 (HealthDay News) -- Weight-loss surgery appears to have an additional side benefit -- it may improve urinary incontinence symptoms in women, according to a new study.
The study found that nearly half of women in a weight-loss surgery program reported having incontinence prior to the procedure. After surgery, most of those women said their urinary symptoms either improved or disappeared, said study researcher Dr. Leslee Subak, professor of obstetrics, gynecology and reproductive sciences at the University of California San Francisco School of Medicine.
The women "lost almost 30 percent of their body weight, and about two-thirds who had incontinence at the start were cured at one year with that amount of weight loss. Among those who continued to have incontinence, their incontinence frequency improved a lot," Subak said.
Subak's team is due to present the findings this week at the American Urogynecologic Society and the International Urogynecological Association 2014 scientific meeting in Washington, D.C. Studies presented at medical meetings are typically viewed as preliminary until published in a peer-reviewed journal.
The women included in the study were severely obese, with a median BMI of 46. A women who is 5 feet 4 inches tall who weighs 268 pounds has a BMI of 46.
Health experts refer to obesity and incontinence as the "twin epidemics." That's because 25 to 50 percent of women have urinary incontinence, according to Subak. Of those, 70 percent are obese, she said.
There are several types of weight loss surgery -- also known as bariatric surgery. Most of the women in the study had procedures known as Roux-en-Y gastric bypass or gastric banding.
The improvement in incontinence symptoms continued during the study follow-up, Subak said.
"Both the weight loss and the improvement in incontinence lasted through three years. At year three, [about] 60 percent had remission," she said. Remissions were defined as less than weekly episodes of incontinence. "A quarter were completely dry," she noted.
The amount of weight loss was the strongest predictor of whether incontinence would improve or go away, Subak found. Losing more made urinary symptom improvement more likely.
