what causes a high hemoglobin a1c

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.
