I have hypothyroidism and I have also been diagnosed with PCOS using labs and ultrasound on ovaries. I am still experiencing horrible fatigue and occasional tingling in my hands and feet. I had thought this was thyroid-related, but now I am wondering about insulin resistance. I am concerned since I have PCOS as well as relatives with type 2 diabetes. I asked my doctor about it and he said that my fasting-glucose levels have always been normal (in June it was 81), my non-fasting serum insulin was normal (level was 8), non-fasting c-peptide was normal (level was 2.9), so it isn’t an issue. I requested the 2hr GTT w/insulin check. He felt it was a waste of my time to get this test, but gave me the order to get it done anyway. I did that yesterday.
1) What would indicate insulin resistance with this test? I am considering switching doctors because I am not sure if the doc I am seeing is right for me.
2) Would a reproductive endocrinologist treat both PCOS and hypothyroidism or do they only treat people with issues in trying to get pregnant?
3) I have heard of many people with PCOS taking Glucophage. If this is a proper treatment for IR, is the extended release version better than the regular?
Thanks for your help.
