Bariatric surgery induces T2DM remission through mechanisms that are partially independent of weight loss, including early metabolic effects on HbA1c and insulin sensitivity.
Surgery improves blood sugar control rapidly, often before significant weight loss, by changing how the body processes nutrients and hormones. This 'metabolic' effect is a key reason why diabetes can go into remission even if weight loss is slow initially.

The early weight-independent metabolic effects on HbA1c, LDL cholesterol, blood pressure, prevention and reduced cardiovascular risks of some of the procedures were already demonstrated in several 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
