Metabolic surgery (bariatric surgery) is recommended for patients with type 2 diabetes and BMI ≥40 kg/m2, or BMI 35.0-39.9 kg/m2 without durable weight loss, and should be considered for BMI 30.0-34.9 kg/m2 without similar improvements, offering superior glycemic control and cardiovascular risk factor reduction compared to lifestyle/medical interventions.

If you have type 2 diabetes and a BMI of 30 or higher, metabolic surgery is a highly effective option, especially if other weight loss methods have failed. It offers superior glycemic control and significant reductions in cardiovascular risk factors. While there are short-term risks, perioperative mortality is low (0.03-0.20%), and the long-term benefits for health and mortality are substantial.

Metabolic surgery is recommended to treat patients who have T2D with BMI ≥40 kg/m2 and in those with BMI 35.0 to 39.9 kg/m2 without durable weight loss and improvement in comorbidities with nonsurgical methods, and should be considered in those with T2D and BMI of 30.0 to 34.9 kg/m2 without similar improvements.
