Hormonal benefits are gained from bariatric procedures, new studysuggests. By Mary Brophy Marcus HealthDay Reporter FRIDAY, May 11 (HealthDay News) -- Obese women often stop gettingtheir periods, but new research suggests weight-loss surgery canhelp regulate their monthly cycles, while also stemming excessivehair growth and skin problems that often accompany significantweight gain. "Obesity is a huge problem in the United States," said study authorChandhana Paka, a fellow in minimally invasive gynecologicalsurgery at Stanford University School of Medicine. "We wanted tosee if bariatric surgery [weight-loss surgery] was a solution tohelping restore menstruation in morbidly obese women whose periodshave become irregular or disappeared." She said hormonal changes that occur when women reach a highbody-mass index (BMI) -- production of more male hormones, forexample -- can lead to menstrual disturbances. BMI is a calculationbased on weight and height.
Paka, who was a resident at St. Luke's-Roosevelt Hospital Center inNew York City when she conducted the study in 2008 and 2009, andher colleagues were scheduled to present their research this weekat the annual meeting of the American College of Obstetricians andGynecologists, in San Diego. For the study, the scientists monitored 126 women planning toundergo bariatric surgery, which involves reducing stomach size tohelp patients cut back on food intake in order to reach a healthyweight. The women were between 18 and 49 years old, and not yet inperimenopause, the time approaching menopause.
Their average agewas 39, Paka said. The average BMI of the study participants was 46, well over thenormal range of about 18 to 24, said Paka. Prior to surgery, 52percent said they had regular periods; 39 percent reportedirregular periods and 22 percent reported no periods. Twelve months after surgery, Paka said, the average BMI was down to33, and 99 percent who had previously reported irregular menses hadstarted having regular periods again.
Close to 82 percent ofpreviously amenorrheic women (those having no periods at all) hadstarted having regular menses, too. "We saw women who within a month after surgery were having theirperiods again. The majority of obese women who had irregular or nomenstruation before surgery reported regular monthly periods aftersurgery," said Paka. "We were surprised to see how fast that canhappen." She said many also experienced a reduction in excess hair growth,hair loss (alopecia), acne, and a skin condition called acanthosisnigricans -- a darkening that can appear in the folds of the skin,around the neck and underarms, for example. Dr.
Thomas Price, an associate professor of reproductiveendocrinology and fertility at Duke University Medical Center inDurham, N.C., said the findings aren't surprising. "All of the results are easily explainable by the hormone changesassociated with weight loss," he said. He explained that as weightloss occurs, hormonal balance improves. Price said the study doesn't touch on the other health problemsassociated with a high BMI. "It doesn't get into the increase inhypertension that goes along with obesity, the increase inarthritis because of trauma to the joints, the increase in sleepapnea that can lead to hypertension and heart disease.
The risk forendometrial cancer goes up. There's no joking around with the risksassociated with obesity," he said. "There is not a downside to weight loss through bariatric surgery,"Price added, but he noted that women wishing to get pregnant shoulddiscuss how long to wait post-surgery before trying to conceive.Sometimes a year's wait is recommended, he said. He also saidhealth insurance doesn't always cover the procedure. Paka pointed out that bariatric surgery is not necessarily asolution for overweight women with fertility issues, but it's oneavenue women can discuss with their obstetricians.
Diet andexercise are always an ideal approach to weight reduction, Pakaadded. She said an obstetrician/gynecologist is often the only physician awoman sees regularly, and preventive care -- which includes helpingpatients reach a healthy weight -- needs to be tackled by theOB/GYN. "If the gynecologist is the gatekeeper of a woman's health, thatmeans it's our responsibility to say, 'Hey, you're having someproblems with your weight. Are you exercising enough? Are youeating well?' said Paka.
But sometimes so many illnesses areoccurring at the same time, she added, "that though I don't thinkit should be what we run to, bariatric surgery is an option thatneeds to be available." Data and conclusions presented at meetings should be consideredpreliminary until published in a peer-reviewed medical journal.
