what is high a1c levels

High A1C levels indicate elevated average blood sugar levels over the past 2-3 months. The A1C test measures the percentage of hemoglobin in your red blood cells that is coated with sugar (glycated hemoglobin). Here’s what the A1C levels 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 manage your blood sugar through lifestyle changes, medication, or other treatments.
