what raises a1c the most

Several factors can significantly raise your A1C levels, including:

• High Blood Sugar Levels: Consistently high blood glucose levels over time are the primary cause of elevated A1C.
• Poor Diabetes Management: Inadequate control of diabetes through diet, exercise, or medication can lead to higher A1C levels.
• Certain Medical Conditions: Conditions like severe anemia, kidney failure, or liver disease can falsely increase A1C results.
• Medications: Some medications, such as opioids and certain HIV drugs, can also affect A1C levels.
• Lifestyle Factors: Lack of physical activity, poor diet, and stress can contribute to higher blood sugar levels and, consequently, higher A1C.

It's important to work with your healthcare provider to identify and address the underlying causes of elevated A1C.
