what is the difference between blood sugar and a1c

Blood sugar and A1C are both measures of glucose levels in the body, but they provide different types of information:

• Blood Sugar: This refers to the amount of glucose in your blood at a specific moment. It is typically measured using a glucometer and provides a snapshot of your current glucose level. Blood sugar levels fluctuate throughout the day based on food intake, physical activity, and other factors.

• A1C (Hemoglobin A1C): This test measures your average blood sugar levels over the past 2-3 months. It reflects the percentage of hemoglobin in your red blood cells that has glucose attached to it. A1C is expressed as a percentage and is used to diagnose prediabetes, diabetes, and to monitor long-term glucose control.

Aspect Blood Sugar A1C

Measurement Momentary glucose level Average glucose over 2-3 months
Frequency Multiple times a day (if diabetic) Every 3-6 months (for monitoring)
Purpose Immediate glucose management Long-term glucose control assessment

Both measures are important for managing diabetes, but they serve different purposes in understanding and controlling blood sugar levels.
