what is a dangerous a1c level

An A1C level is considered dangerous when it indicates poorly controlled diabetes, which can lead to serious health complications. Here’s a breakdown of A1C levels and their implications:

A1C Level (%) Interpretation

Below 5.7 Normal
5.7 - 6.4 Prediabetes
6.5 or above Diabetes

• A1C ≥ 9%: This is considered very high and indicates poor blood sugar control. It significantly increases the risk of complications such as nerve damage, kidney disease, and cardiovascular issues.
• A1C ≥ 10%: Extremely high and requires immediate medical attention to prevent severe complications.

If your A1C is consistently high, consult your healthcare provider to adjust your diabetes management plan, which may include lifestyle changes, medication, or insulin therapy.
