Re: does a blood sugar reading of 170 mean you have diabetes?
Non-diabetics can reach as high as 180 after a high carb meal, although most people only hit 140. What makes the difference is whether you get symptoms with your numbers. For example, when I hit about 180-200, my high blood sugar symptoms kick in: VERY frequent urination, extreme unquenchable thirst, irritability. Keep an eye on things anyhow since you are predisposed to diabetes from your mother anyhow.
