What is HbA1c?
HbA1c (glycated hemoglobin) reflects your average blood sugar over the past 2-3 months. It shows what percentage of hemoglobin has sugar attached to it.
Why HbA1c Matters
HbA1c is the gold standard for diabetes diagnosis and management. It provides a long-term picture of blood sugar control, unlike daily glucose readings.
Symptoms of Low HbA1c
- May indicate anemia

Symptoms of High HbA1c

- Increased thirst
- Fatigue
