Purpose: A remission of type 2 diabetes mellitus (T2DM) is one of the major goals of the contemporary bariatric surgery. The goal of our study is to identify predictors of short-term postoperative diabetes remission in order to facilitate preoperative patient selectionMaterials and Methods: Two hundred forty-five obese (body mass index (BMI) ≥35 kg/m2) T2DM subjects who underwent laparoscopic Roux-en-Y gastric bypass (RYGB) were followed up to 1 year after bariatric surgery. Diabetes remission was defined as hemoglobin A1c (HbA1c) ≤6 % and fasting blood glucose (FBG) <100 mg/dl in absence of all diabetic medications.Results: Twenty-six percent of the patients seen in f/u achieved complete remission at 1 year. Average Hba1c decreased from 8 to 6.7 % and 6.4 % after 6 and 12 months, respectively. Regression analysis showed that age (p = 0.01), number of diabetes complications (p = 0.03), family history of diabetes (p = 0.04), preoperative use of insulin (p = 0.04), and peri- and postoperative weight loss (p = 0.05, for both) were the best preoperative predictors of diabetes remission at 6 and 12 months (R<sup>2</sup> = 0.3).Conclusion: Younger patients, with fewer diabetic complications, no family history of diabetes, not using insulin, and with greater peri- and postoperative weight loss were the best candidates to achieve a rapid diabetes remission after RYGB.
