Hi & Low Blood Sugar: A low blood sugar is normally less than 65 mg/dl, though some may have symptoms before that point. Elevated blood sugars are >99 fasting or >139 around 2 hr after eating. Diabetes range is >125 fasting or >199 at 2 hr after eating. Some would say that > 199 before 2 hr is in the diabetes range.
