In order to be diagnosed with pre-diabetes you need a fasting blood sugar from 100-125, or an A1C over 5.7. Your
blood sugars if anything, are too
low. You could be suffering from hypoglycemia (
low blood sugar) which sometimes precedes diabetes. Or if your lows (under 70) are after how carb meals it could be something called reactive hypoglycemia. I am also very puzzled why your doctor would prescribe medication for someone whose blood sugar never rises above the 90s???
