what does high hgb a1c mean

A high Hemoglobin A1C (HbA1c) level indicates that your average blood sugar levels have been elevated over the past 2-3 months. Here’s what the results typically mean:

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

A high HbA1c level suggests that your blood sugar is not well controlled, which can increase the risk of diabetes-related complications such as heart disease, kidney damage, and nerve damage. If your HbA1c is high, it’s important to work with your healthcare provider to adjust your treatment plan, which may include lifestyle changes, medication, or insulin therapy.
