Effect of Gastric Bypass Surgery on Diabetes Status and Microvascular Complications in Obese Type 2 Diabetic Patients

This study evaluates the long-term benefits of Roux-en-Y gastric bypass (RYGB) on type 2 diabetes mellitus, focussing on the prevalence and predictors of T2DM improvement and remission after RYGB, and subsequently relapse of type 2 diabetes mellitus after RYGB. Moreover, the study evaluates the possible effect of RYGB on diabetic microvascular complications such as nephropathy and retinopathy. Finally, the study provides insight into the factors influencing glucose-insulin homeostasis after RYGB, including altered microbiota diversity and bile acid levels.
