That type 2 diabetes remission may be induced by bariatric surgery in patients with grade 2 (body mass index [BMI] ≥35) and grade 3 (BMI ≥40) obesity soon after operation and preceding weight loss has stimulated new ideas regarding diabetes treatment. Some investigators have proposed surgical intervention for patients with type 2 diabetes with grade 1 obesity (BMI ≥30),1 with some even proposing bariatric surgery as the primary treatment for patients with type 2 diabetes and BMI as low as 27.2 The term metabolic surgery is commonly used to describe this class of surgical procedures because they primarily modify a patient's physiology for the better as opposed to simply correcting or removing an anatomic defect.
