I am prediabetic with higher blood sugar and insulin levels. l just had a 3 hour glucose tolerance test. fasting sugar is 63, insulin is 2. meaning?

Unusual: Your Insulin is appropriately suppressed for a low fasting blood sugar. It isn't what we usually see in patients with pre-diabetes, however. What did the rest of your ogtt look like? Hba1c?

Doesn't matter: The numbers aren't really important or valuable. If you're overweight and have high glucose (particularly with a positive family history) you need education, diet, exercise, weight reductio and maybe medication -- not just a diagnosis. The diagnosis doesn't help you get healthier.
