what is a dangerous level of a1c

An A1C level is considered dangerous when it indicates poor blood sugar control over time. Here are the general guidelines:

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

An A1C level above 8% is particularly concerning as it indicates a higher risk of diabetes-related complications, such as:

• Cardiovascular disease
• Kidney damage
• Nerve damage
• Vision problems

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