I have PCOS, but I don't have any insulin issues. I'm sure they could develop in time, perhaps?
She may have tested your FSH, LH, cholesterol, testosterone and blood sugar levels, among some other things - but those are the most popular.
You'll likely be on Glucaphage (or Metformin, which is the generic). Do some reading on it, it works very well for some, but for others it doesn't. There are side effects with it, and it does work best with a lower carb diet. SBD is a great diet for those with PCOS, particularly if you're going on Met.
If you have any questions, please feel free to PM me.
