Decoding Your A1c Levels: A Simple Chart for Prediabetes & Diabetes
Understanding your A1c levels is crucial for managing your health, especially if you are at risk of or have been diagnosed with prediabetes or diabetes. This article breaks down what A1c is, why it's important, and provides a simple chart for easy interpretation. We'll also cover factors that can affect your A1c and what you can do to maintain healthy blood sugar levels.
What is A1c?
A1c, also known as Hemoglobin A1c or HbA1c, is a blood test that reflects your average blood sugar (glucose) levels over the past 2-3 months. It works by measuring the percentage of your red blood cells that have glucose attached to them. The higher your blood sugar levels, the more glucose attaches to your hemoglobin. Unlike a fasting blood sugar test, which gives a snapshot of your current glucose level, A1c provides a longer-term view. This makes it a valuable tool for diagnosing prediabetes, diabetes, and monitoring how well your diabetes treatment plan is working.

Knowing your A1c levels allows you and your healthcare provider to:
- Diagnose Prediabetes and Diabetes: An A1c test can identify if you have prediabetes (where your blood sugar levels are higher than normal, but not high enough to be diagnosed as diabetes) or diabetes.
- Monitor Diabetes Management: For people with diabetes, regular A1c tests help track how well their blood sugar is being controlled. It gives a comprehensive picture of how diet, exercise, and medication are impacting their blood sugar over time.
- Prevent Complications: Keeping your blood sugar within the target range recommended by your doctor can help prevent or delay long-term complications of diabetes, such as heart disease, kidney disease, nerve damage, and vision loss. The A1c test provides the information necessary to effectively take preventative measures.
A1c Levels Chart
Here's a simple chart to help you understand what your A1c levels mean:
| A1c Level | Category | What it Means |
|---|---|---|
| Below 5.7% | Normal | Indicates normal blood sugar levels. |
| 5.7% - 6.4% | Prediabetes | Suggests a higher risk of developing diabetes. Lifestyle changes can help prevent or delay the onset of diabetes. |
| 6.5% or Higher | Diabetes | Indicates that you have diabetes. Requires a management plan to control blood sugar levels. |
Note: This chart is a general guideline. Your doctor may have specific A1c target goals based on your individual health profile.
Factors That Can Affect A1c Accuracy
While A1c is a reliable test, certain factors can affect its accuracy:
- Anemia and Hemoglobinopathies: Conditions that affect red blood cells, such as anemia (low red blood cell count) and hemoglobinopathies (abnormal hemoglobin), can interfere with A1c results.
- Kidney Disease: Kidney disease can affect the lifespan of red blood cells, which can impact A1c accuracy.
- Pregnancy: Pregnancy can sometimes lead to artificially lower A1c results.
- Certain Medications: Some medications can affect red blood cell production or survival, potentially influencing A1c levels.
- Ethnicity: Some studies suggest that A1c levels may differ slightly across different ethnicities.
If any of these factors apply to you, be sure to discuss it with your doctor. They may need to use alternative tests or interpret your A1c results with caution.
Maintaining Healthy A1c Levels
Whether you have prediabetes or diabetes, here are steps you can take to manage your A1c levels:

- Follow a Healthy Diet: Focus on whole, unprocessed foods, including fruits, vegetables, lean proteins, and whole grains. Limit sugary drinks, processed foods, and saturated fats. Work with a registered dietitian or certified diabetes educator for personalized dietary guidance.
- Engage in Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity aerobic exercise per week, such as brisk walking, swimming, or cycling. Include strength training exercises at least twice a week.
- Maintain a Healthy Weight: Losing even a small amount of weight can significantly improve blood sugar control.
- Monitor Blood Sugar Levels Regularly: If you have diabetes, regularly check your blood sugar levels using a blood glucose meter, as directed by your doctor. This will help you understand how your diet, exercise, and medication affect your blood sugar.
- Take Medications as Prescribed: If you have diabetes, take your medications as prescribed by your doctor. Don't skip doses or change your medication regimen without consulting your doctor.
- Manage Stress: Stress can raise blood sugar levels. Find healthy ways to manage stress, such as meditation, yoga, spending time in nature, or talking to a therapist.
- Get Regular Checkups: See your doctor regularly for A1c tests and other health screenings. This will help you track your progress and make any necessary adjustments to your treatment plan.

Prediabetes is a warning sign that you are at high risk of developing type 2 diabetes. Having an A1c level in the prediabetes range (5.7% - 6.4%) indicates that your blood sugar levels are higher than normal, but not high enough to be diagnosed as diabetes. Making lifestyle changes such as diet and exercise can prevent the progression of prediabetes to full-blown type 2 diabetes.
Diabetes is a chronic condition where the body doesn't make enough insulin or can't effectively use the insulin it produces, leading to high blood sugar levels. A diagnosis of diabetes is confirmed if your A1c level is 6.5% or higher. This requires a management plan including medication, diet and excercise in order to manage the disease.
Conclusion
Understanding your A1c levels is key to managing your blood sugar and preventing or controlling prediabetes and diabetes. By using the chart provided, and working with your healthcare provider, you can take proactive steps to improve your health and reduce your risk of complications. Remember, knowledge is power – especially when it comes to managing your health. By staying informed and taking action, you can live a healthier and happier life.
