Predictors of Long-Term Remission and Relapse of Type 2 Diabetes Mellitus Following Gastric Bypass in Severely Obese Patients.

Background: Diabetes remission is not observed in all obese patients with type 2 diabetes submitted to bariatric surgery. Relapses occur in patients in whom remission is achieved. We investigated the factors associated with long-term (≥3 years) remission and relapse of type 2 diabetes after Roux-en-Y gastric bypass (RYGB) in these patients.
