Bariatric surgery as a treatment of type 2 diabetes

Obesity has reached epidemic proportions, predisposing to the development of type 2 diabetes and cardiovascular diseases. Weight loss is a major objective, although often difficult to achieve with medical treatments. Bariatric surgery has proven its efficacy in obtaining marked and sustained weight loss, and is also associated with a significant improvement in insulin resistance, beta cell function, lipid metabolism, blood pressure and even diabetes remission. We examined the long-term effect of Roux-en-Y gastric bypass (RYGB, a predominantly restrictive procedure) in a patient with uncontrolled type 2 diabetes. One year after surgery, the patient had lost 30% of initial weight with a significant improvement in blood pressure, withdrawal of cholesterol-lowering therapy, complete remission of diabetes.
