If you have Diabetes?! You must know about HbA1C , or A1c.
A1c tells you the average level of glucose (sugar) in your blood over the past three months.
It is reported as a percent (for example 7%). Knowing your A1c tells you about your risk for complications of diabetes, such as blindness, kidney disease and amputations, heart attacks and stroke.
Whenever you have high A1c you will have higher risk for complication.
