What should your fasting blood sugar be?

By Dr. Priyanka Wali

A fasting blood sugar should be less than 100 in order to be considered normal.  A fasting blood sugar of >100 to 125 is consistent with prediabetes.  Fasting blood sugar levels of 126 or greater is diagnostic of diabetes.

If your fasting blood glucose is consistent with prediabetes or type 2 diabetes, we recommend that you speak with your physician.
