Is Your A1c High? How to Convert A1c to Average Blood Glucose (eAG)
Understanding your blood glucose levels is crucial, especially if you're managing diabetes or prediabetes. One of the key metrics for this is the A1c test, which provides an average of your blood sugar levels over the past 2-3 months. If your A1c is high, it's a signal to take action. This article explains what a high A1c means, how to convert it to estimated Average Glucose (eAG), and what steps you can take to manage your blood sugar effectively.
What is A1c and Why Does It Matter?
The A1c test, also known as Hemoglobin A1c, measures the percentage of your red blood cells that have glucose attached to them. This gives doctors an overview of your blood sugar control over a period of time, rather than just a snapshot at a single moment. It's a crucial tool for diagnosing prediabetes and diabetes and for monitoring how well diabetes treatment plans are working. Consistently high A1c levels can lead to serious health complications, including:
- Heart Disease: Elevated blood sugar can damage blood vessels and increase the risk of heart attacks and strokes.
- Kidney Disease (Nephropathy): High glucose levels can harm the filtering units of the kidneys.
- Nerve Damage (Neuropathy): Persistently high blood sugar can damage nerves throughout the body, causing pain, numbness, and other complications.
- Eye Damage (Retinopathy): Elevated glucose can damage the blood vessels in the retina, potentially leading to vision loss.
Regular A1c testing helps you stay on top of your blood sugar management and reduce the risk of these serious health problems.
Understanding A1c Levels: What's Considered High?
A1c results are reported as a percentage. Here's a general guide to interpreting A1c levels:
- Normal: Less than 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
If your A1c level falls into the prediabetes or diabetes range, your doctor will likely recommend lifestyle changes and, potentially, medication to help you manage your blood sugar. Keep in mind that these are general guidelines and your target A1c level may be different based on your individual health profile. Always discuss your results with your healthcare provider.
Converting A1c to Estimated Average Glucose (eAG)
While A1c is a percentage, Estimated Average Glucose (eAG) provides the same information in a way that many people find easier to understand. eAG is reported in the same units (mg/dL or mmol/L) as your daily blood sugar readings. It gives you a sense of what your average blood glucose level has been over the past 2-3 months.
The relationship between A1c and eAG is linear, and you can use a simple formula to convert between the two. However, online A1c to eAG calculators make the process even easier.
Here is the formula for converting A1c to eAG in mg/dL:
eAG (mg/dL) = (28.7 x A1c) - 46.7
And here’s the formula for converting A1c to eAG in mmol/L:
eAG (mmol/L) = (1.59 x A1c) - 2.59

For example, let’s say your A1c is 7.0%. Using the formula for mg/dL:
eAG (mg/dL) = (28.7 x 7.0) - 46.7 = 200.9 - 46.7 = 154.2 mg/dL
So, an A1c of 7.0% corresponds to an estimated average glucose of about 154 mg/dL.
To provide a more convenient reference, here's an example conversion table. Note that the data below is an illustrative example, and may not exactly match what is generated by a calculator. Always consult with your physician about your specific case.
| A1c (%) | eAG (mg/dL) | eAG (mmol/L) |
|---|---|---|
| 6.0 | 126 | 7.0 |
| 7.0 | 154 | 8.6 |
| 8.0 | 183 | 10.2 |
| 9.0 | 212 | 11.8 |
What to Do If Your A1c is High
If your A1c results are high, it's essential to take proactive steps to lower your blood sugar and prevent complications. Here are some key strategies:
-
Consult Your Doctor: The first step is always to discuss your A1c levels with your healthcare provider. They can help you understand your results, identify the underlying causes of high blood sugar, and develop a personalized treatment plan.
-
Lifestyle Modifications: Often, lifestyle changes can significantly impact A1c levels. This includes:
- Diet: Focus on a balanced diet rich in fruits, vegetables, lean protein, and whole grains. Limit sugary drinks, processed foods, and refined carbohydrates. Consider working with a registered dietitian to develop a meal plan that fits your needs.
- Exercise: Aim for at least 30 minutes of moderate-intensity exercise most days of the week. Activities like walking, swimming, and cycling can help improve insulin sensitivity and lower blood sugar.
- Weight Management: If you are overweight or obese, losing even a small amount of weight can improve your blood sugar control.
- Stress Management: Chronic stress can elevate blood sugar levels. Practice relaxation techniques like meditation, yoga, or deep breathing exercises to manage stress.
- Adequate Sleep: Aim for 7-8 hours of quality sleep each night. Sleep deprivation can negatively impact blood sugar control.
-
Medication: Depending on the severity of your high blood sugar and your individual health circumstances, your doctor may prescribe medication to help lower your A1c. Common medications for diabetes include metformin, sulfonylureas, DPP-4 inhibitors, SGLT2 inhibitors, and insulin.

-
Regular Monitoring: Monitor your blood sugar regularly, as directed by your doctor. This will help you track your progress and make adjustments to your treatment plan as needed. Regular A1c tests are also crucial for monitoring long-term control.
-
Diabetes Education: Consider enrolling in a diabetes education program. These programs provide valuable information and support to help you manage your diabetes effectively.
The Importance of Consistent Monitoring and Action
Managing blood sugar is an ongoing process. By understanding your A1c levels, converting them to eAG, and taking proactive steps to manage your blood sugar, you can reduce your risk of complications and live a healthier life. Don't hesitate to work closely with your healthcare team to develop a personalized plan that meets your individual needs and goals. Consistent monitoring and prompt action are key to keeping your blood sugar in check.
