Current bariatric surgery guidelines (BMI >= 35, or 30-34.9 with comorbidities) may need re-evaluation due to the efficacy of pharmacotherapy.
If your BMI is between 30 and 40, you may not need surgery. Ask your doctor about GLP-1 medications, which are now effective enough to potentially replace surgery for many patients.

- 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
