Bariatric surgery, particularly malabsorptive and mixed procedures like Roux-en-Y gastric bypass and biliopancreatic diversion, leads to significant resolution or improvement of type 2 diabetes, often independent of or preceding significant weight loss.
Surgery can put type 2 diabetes into remission for many patients, sometimes before significant weight loss occurs, due to hormonal changes in the gut.
GoodSupportsHIGH confidence
Recovery from type 2 diabetes was established in 76.8% of the patients who underwent bariatric surgery.
Why this rating
Based on meta-analyses and cohort studies.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
