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: If you make significant changes to your diet, exercise, or medication, you may see improvements in your A1C within 2-3 months.
- Consistency: Maintaining consistent blood sugar control is key to lowering your A1C over time.
