There is mounting evidence that bariatric surgery leads to higher remission rates of type 2 diabetes than any conventional medical treatment, lifestyle intervention, or medically supervised weight loss program. Although remission rates of type 2 diabetes may be as high as 66.7 % after gastric bypass and 28.6 % after gastric band, very few bariatric surgery studies report long-term results with sufficient patient follow-up to minimize biased results. Hence, trials that directly compare bariatric surgery procedures with medical and lifestyle intervention for patients with type 2 diabetes are the best candidate for assessing the role of bariatric surgery in diabetes remission. ⋯ Intensive lifestyle intervention is also superior to conventional treatment for inducing remission of type 2 diabetes, with remission rates of type 2 diabetes between 10 and 15 % at 1 year of follow-up. Bariatric surgical procedures, especially RYGB, are more effective at inducing initial type 2 diabetes remission in obese patients, but more information is needed about the long-term durability of comorbidity control and complications after bariatric procedures. In the meantime, all efforts should be directed toward primary prevention of type 2 diabetes, given the encouraging results of lifestyle intervention studies.
