Weight-Loss Surgery May Benefit Very Obese Teens
By EJ Mundell
FRIDAY, Nov. 6, 2015 (HealthDay News) — Weight-loss surgeries, long used by obese adults to drop excess pounds, may provide long-lasting health benefits to very obese teenagers, a new study finds.
The study of extremely obese teens found that, three years after either gastric bypass surgery or a procedure called sleeve gastrectomy, the average patient had lost 27 percent of his or her original weight.
“We found significant improvements in weight, cardiometabolic health and weight-related quality of life at three years after the [weight-loss] procedure,” wrote a team led by Dr. Thomas Inge, of Cincinnati Children’s Hospital Medical Center.
His team published the findings online Nov. 6 in the New England Journal of Medicine, to coincide with a planned presentation of the findings at the Obesity Week annual meeting in Los Angeles.
Outcomes from the two types of weight-loss surgery were examined in the new study. In a gastric bypass, surgeons make a pouch at the top of the stomach that holds about a cup of food. That pouch is then attached directly to the middle portion of the small intestine, rerouting food past the first section of the gut.
In a sleeve gastrectomy, surgeons remove more than 85 percent of the stomach and shape the remainder into a sleeve or tube, but they don’t alter how the food travels through the gut. Weight loss with sleeve gastrectomy is generally slower than gastric bypass, and for some patients, this procedure is the first step before a full bypass.
In the study, Inge’s team tracked three-year outcomes for 242 very obese teens averaging 17 years of age. The teens had an average body-mass index (BMI) of 53.
BMI is a measurement of weight and height. A person with a BMI of 25 is typically considered overweight, and the threshold for obesity begins at a BMI of 30. A 5-foot 7-inch, 17-year-old girl weighing 340 pounds would have a BMI of 53.
