Answered by Dr. Emily Carter, MD 🩺
The A1C test reflects your average blood sugar levels over the past 2 to 3 months, as it measures the percentage of glucose-coated hemoglobin in your red blood cells. Since red blood cells regenerate approximately every 3 months, significant changes in your A1C level typically take 2 to 3 months to become evident.
- Lifestyle changes (e.g., diet, exercise) or adjustments in medication can influence your A1C over this period.
- Frequent monitoring is recommended for individuals managing diabetes or prediabetes to track progress.
