Obese patients type 2 diabetes (T2DM) who underwent Roux-en-Y gastric bypass (RYGB) surgery had greater weight loss and other sustained improvements compared with intensive medical/weight management of the disease in a clinical trial that further confirmed the feasibility of conducting a larger trial to compare bariatric surgery with other interventions.

Data support bariatric surgery as a therapeutic strategy to manage T2DM.
How the Study Was Conducted:
Authors tested the feasibility of conducting a larger trial to determine the long-term effect of RYGB compared with intensive medical/weight management in obese patients (body mass index 30 to 42) with T2DM. The trial analyzed data from 38 participants (19 in the RYGB group and 19 in the medical/weight management intervention).
At one year, more patients in the RYGB group than the medical/weight management group (58 percent vs. 16 percent, respectively) achieved HbA1c below 6.5 percent and fasting glucose below 126 mg/dL. Other outcomes, including HbA 1c , weight, waist circumference, fat mass, lean mass, blood pressure and triglyceride levels, decreased more and high-density lipoprotein cholesterol increased more after RYGB than the nonsurgical intervention.
“These differences may help inform therapeutic decisions for diabetes and weight loss strategies in obese patients with type 2 diabetes until larger randomized trials are performed.”
