what is high a1c mean

A high A1C level indicates that your average blood sugar levels have been elevated over the past 2-3 months. The A1C test measures the percentage of your red blood cells that have sugar-coated hemoglobin. Here’s what the A1C ranges mean:

• Normal: Below 5.7%
• Prediabetes: 5.7% to 6.4%
• Diabetes: 6.5% or above

A high A1C level (6.5% or higher) suggests that your blood sugar is not well controlled, which increases the risk of diabetes-related complications such as heart disease, kidney damage, and nerve damage. If your A1C is high, it’s important to work with your healthcare provider to adjust your treatment plan, which may include lifestyle changes, medication, or both.
