Glycated hemoglobin Hb A1c is used as a major marker for the onset of complications in patients with type 1 and type 2 diabetes.
It's useful because it shows the average blood sugar for about 3 months, but the limitations are also clear.
● There is a lack of information on acute blood sugar fluctuations and acute complications such as hypoglycemia and hyperglycemia.
● Failure to identify the magnitude and frequency of glucose changes within and between days.
● Hb A1c measurement results are inaccurate and confusing under certain conditions such as anemia, hemoglobinopathy, iron deficiency, and pregnancy.
● Even in the absence of the above specific conditions, there are cases where Hb A1c does not accurately reflect average blood sugar.
⇒ Supplementation through continuous glucose monitoring CGM is necessary.
