Decoding the 4 PCOS Phenotypes: Which one are you?

PCOS is not a monolithic diagnosis. In the clinical world, we recognize four distinct phenotypes that dictate how your body responds to treatment, nutrition, and stress. Understanding your specific type is the first step toward true hormonal balance.

1. Insulin-Resistant PCOS

This is the most common form, driven by high insulin levels that signal the ovaries to produce excess testosterone. Management focuses on blood sugar stability and metabolic health.

2. Inflammatory PCOS

Driven by chronic low-grade inflammation, this type often presents with digestive issues, joint pain, and skin flare-ups. The focus here is on anti-inflammatory nutrition and gut health.

3. Adrenal PCOS

Unlike other types, adrenal PCOS is often triggered by an abnormal stress response. These individuals often have high DHEA-S levels while their insulin and other markers remain normal.

4. Post-Pill PCOS

A temporary surge in androgens that occurs after stopping hormonal birth control. This usually resolves with time and targeted nutritional support.
