Metabolic surgery (RYGB, SG, BPD) is more effective than conservative medical therapy for achieving remission of Type 2 Diabetes Mellitus (T2DM) and improving glycemic control, regardless of the patient's preoperative BMI.
If you have Type 2 Diabetes, especially if medications aren't controlling your blood sugar, metabolic surgery (like gastric bypass or sleeve gastrectomy) is clinically proven to be more effective than drugs or diet alone for achieving remission and preventing long-term complications, regardless of your current weight.
GoodSupportsHIGH confidence
Several meta-analyses show the superiority of metabolic surgery for T2DM remission and glycemic control in comparison to medical therapies... Rubino et al. showed in a meta-analysis of 15 studies... that glycemic control was more favorable following surgery than with medical therapy and lifestyle change independent of BMI.
Why this rating
Based on multiple meta-analyses of RCTs and observational studies (e.g., Rubino 2016, SOS study), though the paper itself is a review.
