Why take metformin for PCOS?

Metformin is used for PCOS primarily because it improves insulin resistance, a core issue in many PCOS cases, which helps lower high insulin levels, reduce excess androgen (male hormone) production, regulate periods, and support ovulation for fertility. By making cells more responsive to insulin, it decreases the pancreas's need to overproduce it, thereby improving hormonal balance, controlling symptoms like acne/hair growth, and potentially reducing risks for conditions like prediabetes and high cholesterol, say Children's Hospital Colorado, Drugs.com, and National Institutes of Health (.gov).

The root cause of PCOS isn't fully known but stems from a complex mix of genetics, hormonal imbalances (especially insulin resistance and high androgens), and environmental factors, leading to disrupted ovulation and metabolic issues.

This triggers symptoms like irregular periods, acne, hair growth, and inflammation, often running in families and influenced by lifestyle.
