An A1C level of 7.8% is considered high and indicates diabetes. Here’s what the A1C ranges mean:

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

For most people with diabetes, the target A1C is 7% or less. A level of 7.8% suggests that blood sugar management needs improvement. Higher A1C levels are associated with an increased risk of diabetes complications, such as heart disease, kidney damage, and nerve problems.

If your A1C is 7.8%, consult your healthcare provider to adjust your treatment plan, which may include lifestyle changes, medication, or insulin therapy. Regular monitoring and follow-up are essential to manage diabetes effectively.
