Hey,
I'm new too, and just wanted to say that I am equally confused about IR!
I was just given a link to read, and apparently your blood pressure and cholesterol levels, as well as if you're obese, can play a role in an IR dx.
I was told I was IR by my endo, but I don't know why - I'm guessing it's my cholesterol, waist size, and glucose levels...but I am not considered diabetic.
Again, I don't know...
Cheers,
K
