National Institutes of Health-funded researchers found that adults had significant weight loss three years after bariatric surgery, with the majority losing the most weight during the first year. A separate study in teens found few incidences of complications in the first 30 days after bariatric surgery. These studies are part of the Longitudinal Assessment of Bariatric Surgery (LABS) and Teen-LABS. More than one-third of U.S. adults are obese, defined as having a body mass index or BMI of 30 or higher, and almost 17 percent of youth are also obese. Severe obesity is a BMI of 35 or more in adults and teens. BMI measures weight in relation to height.
Both studies are funded by the National Institute of Diabetes and Digestive and Kidney Diseases, part of NIH. The results appear online November 4 in the Journal of the American Medical Association (JAMA) and JAMA Pediatrics, respectively. http://www.nih.gov/news/health/nov2013/niddk-04.htm
