An A1C level is considered dangerous when it indicates poorly controlled diabetes or a high risk of complications. Here’s a breakdown of A1C levels and their implications:

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