Types of PCOS: Insulin-Resistant, Inflammatory & More

PCOS is not one-size-fits-all. The four commonly discussed types are insulin-resistant (the most common), inflammatory (driven by chronic inflammation), adrenal (elevated DHEA-S without insulin issues), and post-pill (temporary after stopping birth control). Knowing your type helps target treatment.

The four types explained

Identifying your type helps you focus on what actually drives your symptoms.

  • Insulin-resistant: high insulin, weight gain, cravings, acanthosis nigricans.
  • Inflammatory: normal insulin but high CRP, joint pain, fatigue, skin issues.
  • Adrenal: elevated DHEA-S but normal testosterone and insulin, often stress-driven.
  • Post-pill: symptoms appear after stopping birth control and often resolve within months.

Frequently asked questions

How do I know which type of PCOS I have?

Blood tests for insulin, DHEA-S, testosterone, and inflammatory markers (CRP) help identify your type. Insulin-resistant is most common, but if your insulin is normal, inflammatory or adrenal causes may be primary.

Does treatment differ by PCOS type?

Yes. Insulin-resistant PCOS benefits most from blood-sugar management. Inflammatory responds to anti-inflammatory diet and gut health. Adrenal needs stress management. Post-pill often resolves with time.
