How can i reduce my hba1c level?

BG control: Hba1c % is almost always elevated because of higher-than-normal average blood sugars, usually in diabetes or prediabetes (impaired fasting glucose, glucose intolerance). Lowering bgs through diet, exercise, or medication should lower hba1c. However, hba1c can be transiently, falsely elevated, so it should be confirmed by repetition and supporting tests, e.g. Fasting bg before any therapy starts.
