Metabolic surgery: roux-en-Y gastric bypass and variables associated with diabetes remission in patients with BMI <35.

Metabolic results of bariatric surgery have determined an expansion of its traditional indications, being increasingly performed in non-severely obese patients, especially in type 2 diabetes mellitus (T2DM). Our aim is to determine the effectiveness of laparoscopic Roux-en-Y gastric bypass (LRYGB) in T2DM remission in patients with body mass index (BMI) below 35 kg/m(2) and the variables associated with T2DM remission after surgery. Retrospective analysis of diabetic patients with BMI <35 kg/m(2) who underwent LRYGB in our center between 2002 and 2010 was done.
