Your HbA1c level of 8.9 is a High HbA1c level.

An HbA1c level of 8.9 % usually means average blood sugar has been elevated over the past 2-3 months. It suggests poor diabetes control. High levels of HbA1c can cause increased thirst, frequent urination, fatigue, blurred vision, slow-healing sores, and frequent infections. This can be caused by type 1 diabetes, type 2 diabetes, or prediabetes. Further tests are often needed to identify the cause and guide appropriate treatment.

High HbA1c levels may indicate underlying health problems. The normal range is typically between 4 % and 5.7 %. If your levels are outside this range, it's important to speak with a healthcare provider. Consulting a doctor is recommended to determine the cause and appropriate next steps.

Misdiagnosis is more common than people think—and the consequences can be serious. Delayed treatment, unnecessary medication, or worse. If you want a second opinion on your blood work, one option is to upload it to a site like wholebodyprotocol.com, where world-class doctors review your results. They charge a small fee—around $90 (though you'll want to check the latest price as it fluctuates)—and email you a detailed report. With over 12 million people affected by misdiagnosis every year, that little bit of extra peace of mind can go a long way.
