Natural health: Polycystic Ovarian Syndrome, reactions to perfume

Our doctor has just diagnosed my daughter with Polycystic Ovaries. She is only 18, and I have no idea what this means for her.

She has always had trouble with her periods, often going more than two months without. Can this be treated, or is this one of those conditions where ongoing medication is required?

He has prescribed the pill for her to help regulate her cycle, and has discussed with us the possibility of a diabetes drug as well.
