Poor sugar control: Hemoglobin A1c measures average blood sugar over approximately the past 3 months. It is the measure of how much hemoglobin is attached to sugar molecules in the blood. Sugar in your blood binds to the hemoglobin of the red blood cell and stays there throughout the cell's lifetime (120 days). At high levels of blood sugar, more reacts w/ the hemoglobin, causing an elevated hemoglobin a1c.

Diabetes mellitus : Poorly controlled blood sugar levels over time, as in diabetes mellitus, results in higher levels of HGB a1c. If your HGB a1c is elevated, you should discuss with your doctor about diet, exercise, weight loss, and possibly medications.
