Pattern Overview

Phlegm-Dampness Obstruction is the most common pattern in PCOS, characterized by insulin resistance, obesity, anovulation, amenorrhea, and lipid metabolism disorder. The core pathogenesis is Spleen deficiency causing Phlegm-Dampness accumulation, leading to insulin resistance, elevated androgen production, and chronic anovulation.

Western Mechanism Reference

Phlegm-Dampness Obstruction corresponds to PCOS with obesity and insulin resistance, where hyperinsulinemia and elevated androgen levels contribute to anovulation and metabolic dysfunction.
