Hormonal

Metformin treatment in women with PCOS leads to regularization of the menstrual cycle, reduction in hyperandrogenism, and improvement in cardiovascular risk factors.

If you have PCOS, ask your doctor about metformin. It is the most common medication used for this condition because it helps fix the underlying insulin resistance. This can help restore regular periods, lower male hormone levels, and improve heart health risks. Lifestyle changes like diet and exercise are also recommended, especially if you are overweight.
