A member asked:

M58, what do you say about fasting blood sugar is 140 and two hours after meal is 170. (this with 500 mg glucophage). ?

A doctor has provided 1 answer

Hb A1c: You know that you have diabetes and need to control your blood sugar. For monitoring the control of blood sugar, hemoglobin A1c is a better test than blood glucose. It is good to keep Hb A1c below 7.0
