As far as I know...which I'm still learning about it. You really need an ultra sound and blood tests to find out for sure. My understanding of it, PCOS has mutiple symptoms ...ranging from excessive hair growth, mood swings, acne, irregular periods, weight gain, fatigue, etc. (Varying from person to person.) The list goes on.
I think it is getting more recognized and understood by doctors. Some doctors tend to believe that the root of PCOS is insulin resistance. Research is leading to that too. Some are able to control it thru excerise and diet. If it can't be done by these alone, the doctor may suggest a drug ("Metformin") to help. As I understand it, those with PCOS, are more suscepible to diabetes, high cholestrol, infertility, and being overwieght. Your doctor will know more. There is no surgery or cure...just management. I bought a book called "The New Glucose Revolution : Guide to Living Well with PCOS". I'm still reading it... So, far its pretty good.
Hope this helps alittle. Good Luck to your daughter!
I'm still seeing if anyone knows anymore or has any suggestions....
