Over the past decade, the incidence of type 2 diabetes mellitus (T2DM) has increased significantly. Evidence has shown that a clear association exists between obesity and diabetes development. This association has inspired researchers to explore bariatric surgery as an option for diabetes management and possible disease reversal. Improvement of T2DM using Roux-En-Y gastric bypass (RYGB) is thought to result from from a combination of weight loss, decreased caloric intake, hormonal changes and rearrangement of the gastrointestinal anatomy. Positive outcomes resulting from the procedure include decreased mortality rates, normalization of HbA1c levels, decreased dependence on diabetic medications, and increased insulin sensitivity. Gastric bypass, specifically RYGB, appears to be a promising treatment for T2DM. Due to possible complications and limited research in some populations, treatment should be restricted to patients with a BMI > 35 with concurrent diabetes. Patients with diabetes who qualify should be counseled on the potential benefits of gastric bypass as a viable option for diabetes management.
