Supplementing doctor care with information is wise, imho, totally giving up on doctors however doesn't always worked. When I lived in Central America I could walk into any lab and request any lab test I wanted for something like $16. In the U.S. you need a doctor's order, so if you want some more conclusive tests you might need to deal with a doctor. Everyone's diabetes is different, especially in the early stages, some have more problems with fbg, some with post-prandial, some both. You may be right that your post prandials might be in range, at least for now, due to how you eat. If you want to do an experiment on your own eat something very high carb, then test at one and two hours. You are barely above the optimal for fasting so you are in a good position to make early changes to keep your numbers in check. An advantage to a pre-diabetic diagnosis might be that your insurance would cover test strips so you can continue to monitor your numbers which might change over time.
Zoelula, I have given up on my doctor, that is why I am on this forum. Do those post prandial numbers suggest anything? They are well within normal but the fasting is not quite optimal, at 106 or 105. What does this mean? I can easily understand cholestrol and blood pressure and other variables but blood glucose seems wacky as there are a variety of techniques to measure it and to determine the status. How is it that my BG is normal after I eat but a little outside normal when measure after fasting? Moreover, I have written before as well that my lifestyle is too good to expose me to higher BG numbers. I am really disturbed.
You might be prediabetic. You might want to get an A1C or a OGTT test to further determine if this is the case. If so, don't freak out, but you will want to make some changes in diet and exercise and lose weight if you need to do so to help maintain your blood sugars. Talk to your doctor.
