Mother's Obesity Surgery May Break Cycle in Kids

George Doyle/Thinkstock(NEW YORK) -- Children born to mothers who have undergone weight-loss surgery weigh less than their siblings born before the mother's surgery.

According to a study published in The Proceedings of the National Academy of Sciences, not only were children conceived post-surgery less likely to be obese, they also had fewer risk factors for heart disease and diabetes. Researchers believe that because mothers absorb less fat and fewer calories after their surgery, the nutritional environment in their womb may be altered, training their children's genes to work differently.

While obesity may pass along problems from mother to child, researchers are not yet certain whether the benefits seen by children conceived after weight-loss surgery are permanent.

Additionally, the American College of Obstetricians and Gynecologists points out that a mother's weight when they conceive is not all that matters. While mothers are supposed to gain weight during pregnancy, packing on too many pounds can significantly increase the child's risk of obesity and diabetes.

Weight-Loss Surgery Increases Risk of Alcohol Addiction

iStockphoto/Thinkstock(PITTSBURGH) -- Having Roux-en-Y gastric bypass surgery, where the size of the stomach is reduced and the intestine is shortened, thus limiting how much a person can eat, can increase the risk of alcohol-use disorders, new research suggests.

The study, conducted by researchers at the University of Pittsburgh Medical Center, adds to mounting evidence of a link between having the popular gastric bypass surgery and the symptoms of alcohol-use disorders.

Before the surgery, the nearly 2,000 study participants completed a survey developed by the World Health Organization that is used to identify symptoms of alcohol abuse.

The patients then completed the survey one and two years after their weight-loss surgery.  The study found that 7 percent of patients who had gastric bypass reported symptoms of alcohol use disorders prior to surgery.  The second year after surgery, 10.7 percent of patients were reporting symptoms.

The findings were published Monday in the Journal of the American Medical Association.

"There have been previous studies that show there is a change in alcohol sensitivity in gastric bypass," said Wendy King, a research assistant professor in the department of epidemiology at the University of Pittsburgh Medical Center, and the study's lead author.

King's study is the first to show that with this increased sensitivity there is also an increased risk of alcohol use disorders (AUD), the term used to describe alcohol abuse and dependence.

Dr. Mitchell Roslin, a bariatric surgeon at Lenox Hill Hospital in New York City, said the link between gastric bypass surgery and increased alcohol use has been attributed before to the shifting addiction theory and that this is false. The shifting addiction theory is that if a person has an impulsive drive to eat and the ability to eat large amounts of food is taken away, then he will shift his addiction to another addictive substance, like drugs or alcohol.

"A gastric bypass patient has a small pouch [for a stomach] so alcohol goes straight into the intestine and is absorbed rapidly," said Roslin. "When it is absorbed rapidly, there is a high peak and rapid fall." The higher absorption rate makes alcohol more addictive, he added.

The study also found that the increase in alcohol-use disorders was not seen until the second post-operative year as opposed to the first year after surgery.

"This emphasizes that continuing education about alcohol use is needed until the second year after surgery.  With follow up [patients] need to hear about consumption and what is appropriate," said King.

Study: Weight Loss Surgery Can Regulate Menstrual Cycle, Improve Hair and Skin

Hemera/Thinkstock (NEW YORK) -- New research indicates that weight-loss surgery can help women regulate their menstrual cycles and reduce excessive hair growth and skin problems that go along with extra weight, Health Day reports.

During the study, conducted at St. Luke's-Roosevelt Hospital Center in New York, scientists monitored 126 women ages 18 to 49 who were planning to undergo bariatric surgery, which reduces stomach size to make it easier for patients to decrease their food intake. All of the women involved were not yet approaching menopause. Researchers looked at the women's body mass index, since a high BMI creates hormonal changes, such as production of more male hormones, that lead to disturbances in the menstrual cycle.

The average BMI of the women in the study was 46, much higher than the average range of 18 to 24. Before surgery, 52 percent of women had regular periods, 39 had irregular periods and 22 percent had no periods. After surgery, the average BMI of the women dropped to 33, and 99 percent of the women who previously had irregular periods began menstruating on a regular basis again. Nearly 82 percent of the women who had reported no periods also began getting regular periods as well, according to Health Day.

Additionally, many women experienced less excess hair growth, hair loss, acne and a skin condition known as acanthosis nigricans that causes darkening of the skin, after the surgery.
