does dehydration affect a1c results

Dehydration can potentially affect A1C results, but the impact is generally minimal. Here’s what you need to know:

• A1C Test Basics: The A1C test measures the percentage of hemoglobin in your red blood cells that has glucose attached to it. It reflects your average blood sugar levels over the past 2-3 months.
• Dehydration and Blood Concentration: Severe dehydration can lead to a higher concentration of blood components, including hemoglobin. This might slightly increase the A1C percentage, but the effect is usually not significant.
• Other Factors: Conditions like anemia, kidney disease, or certain medications have a more substantial impact on A1C accuracy than dehydration.

If you suspect dehydration or other factors might affect your A1C results, consult your healthcare provider for further evaluation.
