how long does it take a1c to go down

The A1C test reflects your average blood sugar levels over the past 2-3 months, as it measures the percentage of glucose-coated hemoglobin in your red blood cells. Therefore, changes in your A1C level will typically take 2-3 months to become evident after making lifestyle changes or starting treatment.

Here’s a general timeline:

• 1-2 months: You may start to see small improvements in your blood sugar levels, but these changes may not yet be reflected in your A1C results.
• 2-3 months: Significant changes in your A1C level should be noticeable if you’ve consistently managed your blood sugar through diet, exercise, or medication.

For example, if you lower your average blood sugar from 180 mg/dL to 150 mg/dL, your A1C could drop from 8.0% to 7.0% over this period.
