what causes high a1c levels

High A1C levels are primarily caused by elevated blood sugar levels over time. Here are some common factors that can contribute to high A1C levels:

• Diabetes or Prediabetes: Unmanaged diabetes or prediabetes is the most common cause of high A1C levels.
• Poor Diet: Consuming excessive amounts of sugary or high-carbohydrate foods can lead to elevated blood sugar levels.
• Lack of Physical Activity: Sedentary lifestyles can contribute to insulin resistance and higher blood sugar levels.
• Medications: Certain medications, such as steroids, can increase blood sugar levels.
• Medical Conditions: Conditions like kidney disease, liver disease, or anemia can affect A1C accuracy.
• Stress or Illness: Physical or emotional stress and illnesses can temporarily raise blood sugar levels.

If you have consistently high A1C levels, it’s important to consult with a healthcare provider to identify the underlying cause and develop a management plan.
