Polycystic ovaries: Your symptoms sound consistent with polycystic ovarian syndrome (pcos). This is a common disorder typically caused by Insulin resistance. Typically there is a family history for diabetes. The treatment is to follow a low carbohydrate (low starch) diet, exercise in order to cause weight loss. Metformin is a helpful medication once the diagnosis is established.
