LABS study shows adults had significant weight loss 3 years after bariatric surgery

Second study in teens shows few complications in first 30 days after surgery

National Institutes of Health (NIH)-funded researchers found that adults with severe obesity had significant weight loss 3 years after bariatric surgery, with the majority losing the most weight during the first year. A separate study in teens with severe obesity 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 (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.

LABS found that adults who had either Roux-en-Y gastric bypass or laparoscopic adjustable gastric banding had significant weight loss 3 years after surgery, with the majority losing the most weight during the first year. Researchers identified five different weight change patterns for each surgery. There were also varied improvements to diabetes, abnormal lipids, and high blood pressure among participants who had these health problems prior to surgery. LABS is an ongoing study, and its researchers will conduct longer-term follow-up on participants’ health and weight statuses.

Teen-LABS found that 30 days after surgery short-term complications were low, which researchers view as important information to help doctors and families better evaluate the risks and benefits of the procedure. Teen-LABS investigators will continue to follow participants to determine longer-term health and weight outcomes of bariatric surgery in teens.

NIH launched LABS in 2003 and Teen-LABS in 2007 to assess the short- and longer-term risks and benefits of bariatric surgery among adults and teens with severe obesity.
