Bariatric surgery can cause resolution of the clinical manifestations of type 2 diabetes, as well as improvement. There are data that do not allow the assumption of an absolute cause-and-effect relationship between body weight and type 2 diabetes. The primary risk factor for type 2 diabetes is obesity, and 90% of all patients with type 2 diabetes are overweight or obese. Metabolic surgery is the only diabetes treatment proven to result in long-term remission in 23–60% of patients depending upon preoperative duration of diabetes and disease severity. Reported an overall type 2 DM remission rate of 78% after bariatric surgery with 1–3 years of follow-up. Surgery should also be considered for patients with type 2 DM and BMI 30.0–34.9 kg/m2 if hyperglycemia is inadequately controlled despite optimal treatment with either oral or injectable medications.
