Polycystic Ovary Syndrome (PCOS) is one of the most common endocrine disorders in women, affecting hormone production, ovulation, metabolism, and insulin sensitivity. While it's named for the appearance of multiple cysts on the ovaries, not all women with PCOS have cysts. Symptoms vary widely and may include irregular cycles, acne, facial hair growth, weight gain, and fertility struggles. Functional medicine addresses PCOS by identifying root causes like insulin resistance, adrenal imbalance, inflammation, or gut dysbiosis. Treatment is personalized and may include dietary changes, hormone testing, blood sugar balancing, and natural supplementation to restore hormonal harmony.
