is 6.6 a1c bad

An A1C level of 6.6% is considered elevated and falls within the prediabetes range, which is between 5.7% and 6.4%. However, it is very close to the diabetes threshold of 6.5%. Here’s what it means:

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

While 6.6% is slightly above the prediabetes range, it indicates that your average blood sugar levels over the past 2-3 months are higher than normal. This increases your risk of developing type 2 diabetes and other health complications. It’s important to consult your doctor for further evaluation and to discuss lifestyle changes or treatments to manage your blood sugar levels.
