Patients undergoing bariatric surgery see biggest benefits within first three years

Washington, Nov. 5 (ANI): Researchers have found that obese patients who underwent gastric bypass or laparoscopic adjustable gastric banding surgical procedures experienced substantial weight loss three years after surgery, with most of the change occurring in the first year itself. Led by Anita Courcoulas, M.D., M.P.H., a bariatric and general surgeon at Magee-Womens Hospital of UPMC, researchers used detailed data from the Longitudinal Assessment of Bariatric Surgery (LABS) Consortium, the researchers gathered highly standardized assessments and measures on adult study participants undergoing bariatric surgery procedures and followed them over the course of three years. At baseline, study participants ranged in age from 18 to 78 years of age, 79 percent were women, and the median Body Mass Index was 45.9 kg/m2; 1,738 participants chose to undergo gastric bypass surgery, and 601 underwent laparoscopic gastric banding. In the three-year follow-up after bariatric surgery, the researchers observed substantial weight loss for both procedures, with most of the change occurring during the first year. Participants who underwent gastric bypass surgery or laparoscopic adjustable gastric banding experienced median weight loss of nearly 32 percent and 16 percent, respectively. Additionally, of the gastric bypass surgical participants who had specific obesity-related health problems prior to surgery, 67 percent experienced partial remission from diabetes and 38 percent remission from hypertension. High cholesterol resolved in 61 percent of the participants who underwent bypass surgery. For those who underwent laparoscopic adjustable gastric banding, 28 percent and 17 percent experienced partial remission from diabetes and remission from hypertension respectively, and high cholesterol was resolved in 27 percent of participants. The study has been published online in the Journal of the American Medical Association. (ANI)
