i think 85-90 average blood glucose is a bit of stretch. maybe someone total sedentary and on low carb diet can get 85-90 average. here study, professional cyclysts young men in 20s. fasting 90, hba1c 5.4

The study population consisted of 47 male professional road cyclists, 72 male elite road cyclists and 58 male sedentary blood donors. A significant difference was observed for FPG between sedentary controls (96 +/- 8 mg/dL) and either elite (91 +/- 8 mg/dL; p < 0.001) or professional cyclists (89 +/- 8 mg/dl; p < 0.001). Athletes showed a consistent trend towards higher HbA1c values, reaching statistical significance between sedentary individuals and professional cyclists (5.2 +/- 0.3% versus 5.4 +/- 0.2%; p = 0.017).
Ok I will definitely go back and get on metformin and watch the videos. I check my glucose randomly and never catch it more than 140 even after meals. How can my a1c be so high? I don't understand.
proper thyroid treatment is important and helps with blood sugar control (think about it this way, thyroid controls your metabolism. Metabolism and blood sugar are of course linked).
Your dr is wrong to watch and wait. Hba1c of 6.6 is around 150 on average. normal blood sugars are < 100 on average (totally normal will around 85 - 90). So you are already 50% above normal. Further, it is known that damage occurs and accelerates as Hba1c rises above 5. Nerve damage is also known to occur with blood sugars above 140, though they may occur at low levels.
Bottom line. You should be managed now to normalize your blood sugars. Waiting is just asking for complications to occur (and not all of these will be reversible when you do get good control later).
Recommend you also go to U-tube "Bernstein Diabetes University". He has about 40 educational sessions posted there now. Well worth the watch and study, and then apply to your diabetes management.
I would find a new MD
why wait to control BG by waiting you will only incur damage that puts you closer to complications of going blind and loosing toes. Start now
A T1 diabetic is someone who has an autoimmune attack on there beta cells. That is NOT the same as a T2 that need insulin. A T2 is a T2 even on insulin, and T2 does NOT convert to T1
I cant answer what thyroid meds do to BG
