Does Dehydration Affect A1C Results?

Understanding A1C

The A1C test measures your average blood sugar levels over the past 2-3 months. It is a key diagnostic tool for diabetes and prediabetes.

Can Dehydration Impact A1C?

Yes, dehydration can potentially affect A1C results. Here's how:

• Higher Blood Sugar Concentration: Dehydration reduces blood volume, which can lead to a higher concentration of glucose in the blood, potentially increasing A1C levels.
• Red Blood Cell Lifespan: Severe dehydration may alter the lifespan of red blood cells, which could indirectly affect A1C results.

What Should You Do?

• Stay Hydrated: Drink plenty of water, especially before an A1C test, to ensure accurate results.
• Consult Your Doctor: If you suspect dehydration or have concerns about your A1C results, discuss them with your healthcare provider.
• Monitor Symptoms: Watch for signs of dehydration, such as dry mouth, fatigue, or dark urine, and address them promptly.

Key Takeaway

While dehydration can influence A1C results, it is not the primary factor. Maintaining proper hydration and following your doctor's advice are essential for accurate diabetes management.
