Abstract
Remission of type 2 diabetes mellitus with metabolic surgery is a field of active investigation and development. The extraordinary results obtained in diabetic patients with BMI > 35 kg/m(2) have led investigators to query if similar results could be achieved in patients with BMI < 35 kg/m(2). A few studies have been recently conducted to evaluate the safety, effectiveness, and cost effectiveness of bariatric surgery in diabetic patients with BMI BMI < 35 kg/m(2). However, stronger evidence would be required before insurance coverage is extended for bariatric surgery to all type 2 diabetic patients, in addition to those with BMI ≥ 35 kg/m(2) for whom eligibility is already established. In addition, the hormonal and metabolic mechanisms of diabetes remission after gastrointestinal surgery are yet to be determined. This paper will review the evidence about safety, effectiveness, and cost effectiveness of bariatric surgery in type 2 diabetes mellitus remission and the potential socioeconomic impact of offering bariatric surgery to diabetic patients with BMI BMI < 35 kg/m(2).
