Two types of readings are taken to assess blood sugar levels. Normally blood sugar rises after a meal. Fasting blood sugar is a reading that is taken at least eight hours after eating. A reading two hours after a meal may also be taken to see how much of a difference exists or to detect cases when the body does not react in the normal way.

Normal blood sugar levels: Fasting blood sugar less than 110 mg/dl. Blood sugar two hours after a meal that is less than 140 mg/dl.

Prediabetic levels: Fasting blood sugar between 110 and 125 mg/dl. Blood sugar two hours after a meal that is between 140 and 200 mg/dl.

Diabetic levels: Fasting blood sugar over 125 mg/dl. Blood sugar two hours after a meal that is over 200 mg/dl.
