How the Blood Sugar & HbA1c Works

Fasting sugar under 100 mg/dL is normal, 100–125 is prediabetes and 126 or more is in the diabetes range. Two hours after a meal, under 140 is normal and 200 or more is in the diabetes range.

HbA1c shows your average sugar over about 3 months: under 5.7 % is normal, 5.7–6.4 % is prediabetes and 6.5 % or more is in the diabetes range.

Does one high value mean I have diabetes?

Not always. Doctors confirm diabetes with a second test, unless you have clear symptoms with a very high reading.

Can prediabetes be reversed?

Often, yes. Losing 5–7 % of body weight and 150 minutes of activity a week lowers the risk of diabetes substantially.
