The cause of the PCOS is not known, but there is treatment available. It is believed that the leading cause of the PCOS is insulin resistance. Excessive amount of insulin is unhealthy and may lead to diabetes, certain cancers and heart disease. PCOS might have a genetic predisposition and run in the family, but no gene associated with this condition has been discovered.
The corner stone of treatment for PCOS is to lower insulin resistance and this almost always involves life style changes like exercise and diet. The next step in treatment depends on your age and expectations and includes; medication (contraceptive pills, antiandrogens, Metformin – diabetes medication to control insulin levels), Mirena (medicated intrauterine device to protect the uterus) and surgical (used when attempts at fertility with medication have failed).
