what is a very high a1c

An A1C test measures your average blood sugar levels over the past 2-3 months. The results are reported as a percentage. Here’s what the ranges mean:

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

A very high A1C is typically considered 9% or higher. This indicates poor blood sugar control and a higher risk of diabetes-related complications, such as:

• Heart disease
• Kidney damage
• Nerve damage
• Vision problems

If your A1C is very high, it’s important to work with your healthcare provider to adjust your treatment plan, which may include lifestyle changes, medication, or insulin therapy.
