what causes high a1c

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

• Diabetes or Prediabetes: Unmanaged diabetes or prediabetes is the most common cause of high A1C.
• Poor Diet: Consuming high amounts of sugary or carbohydrate-rich 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 hormonal imbalances can affect blood sugar control.
• Stress: Chronic stress can lead to elevated blood sugar levels due to the release of stress hormones.

If you have a high A1C, it's important to work with your healthcare provider to identify the underlying cause and develop a management plan.
