Insulin resistance (IR) is a major driver of PCOS pathophysiology, present in 65-95% of women with PCOS, and is independent of and exacerbated by obesity.
Insulin resistance is a core feature of PCOS, affecting most women with the condition, regardless of weight. Managing insulin levels is crucial for treating PCOS symptoms and reducing long-term health risks like type 2 diabetes.

- 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
