Risk of Diabetes? Some time ago, I ate my lunch at work, including a little snack. I had to go get off from work that afternoon for a doctor's checkup.  I had all of the tests, including the urine test. I found out that I have had high blood sugar...the doctor asked what I have been eating...she told me to come back in the morning to fast, take the urine test again, and then eat something, then she will give me her report.  The fasting test turned out that I am ok.
    My grandmother (mom's mother) had Type 1 and my grandfather (dad's father) had Type 2....they were the only two I know of who had full diabetes.
       Does this mean in the first test I did that people can tolerate high blood sugar by eating food with sugar or salt in it and not have diabetes, or is this a "precursor" to diabetes? Just wondering.

Summarized question: Is it normal if people can tolerate high blood sugar by eating food with sugar or salt in it and not have diabetes?
