More Support for Bariatric Surgery for Type 2 Diabetes
By Amy Orciari Herman
Two randomized trials in JAMA Surgery add to the growing evidence favoring bariatric surgery for treating obese patients with type 2 diabetes.
In the first, 38 obese adults receiving diabetes medications were randomized either to undergo Roux-en-Y gastric bypass or to participate in an intensive multidisciplinary regimen that included medication, dietary adjustment, exercise, cognitive-behavioral therapy, and group education. At 1 year, the surgery group achieved a higher rate of glycemic control than the interdisciplinary group (58% vs. 16%).
In the second study, 69 obese, diabetic adults were randomized to undergo Roux-en-Y gastric bypass, laparoscopic adjustable gastric banding, or an intensive lifestyle weight loss intervention. At 1 year, the bypass group had lost the most weight. Rates of partial and complete diabetes remission were 50% and 17%, respectively, in the bypass group and 27% and 23% in the banding group. No lifestyle patients achieved partial or complete remission.
