The Link Between Insulin Resistance and PCOS
Understanding the root cause of weight gain and irregular periods
While PCOS is known as a reproductive issue, it is fundamentally a metabolic disorder. Up to 70% of women with PCOS have Insulin Resistance, meaning their cells don't respond properly to the hormone insulin.
The Domino Effect
When cells resist insulin, the pancreas pumps out even more insulin to force the blood sugar down. This high level of insulin in the blood acts as a trigger on the ovaries, causing them to overproduce male hormones (androgens like testosterone).
The Consequences of High Testosterone
These excess male hormones interrupt the normal menstrual cycle, preventing ovulation and leading to irregular periods. They are also responsible for the frustrating physical symptoms of PCOS: facial hair growth, severe acne, and scalp hair thinning.
Breaking the Cycle
By treating the insulin resistance through diet, weight loss, and medications like Metformin (prescribed by an endocrinologist), the insulin levels drop. Consequently, the testosterone levels drop, and the menstrual cycle often regulates itself naturally.
