A high hemoglobin A1C (HbA1c) level indicates elevated average blood sugar levels over the past 2-3 months. Common causes include:

  • Diabetes or Prediabetes: Persistent high blood sugar levels due to insulin resistance or insufficient insulin production.
  • Poor Diabetes Management: Inadequate control of blood sugar through diet, exercise, or medication.
  • Lifestyle Factors: Sedentary lifestyle, unhealthy diet, or obesity.
  • Medical Conditions: Conditions like kidney disease, liver disease, or anemia can affect A1C accuracy.
  • Medications: Certain drugs, such as steroids or HIV medications, may increase blood sugar levels.
  • Stress or Illness: Physical stress or illness can temporarily raise blood sugar levels.

If your A1C is high, consult your healthcare provider to identify the underlying cause and develop a management plan.
