Understanding Your A1c Levels: A Complete Guide with Conversion Chart
Understanding your A1c levels is crucial for managing diabetes and prediabetes. This comprehensive guide breaks down what A1c is, how it's measured, what the different levels mean, and provides a helpful conversion chart. Let's dive in!
What is A1c?
A1c, also known as glycated hemoglobin, is a blood test that reflects your average blood sugar (glucose) levels over the past 2-3 months. It measures the percentage of your red blood cells that have glucose attached to them. The higher your blood sugar levels, the more glucose will be attached to your hemoglobin.
Unlike a daily blood sugar test which gives you a snapshot of your blood sugar at that specific moment, the A1c test offers a more comprehensive overview of your blood sugar control over time. This makes it a valuable tool for both diagnosing and managing diabetes.
Why is A1c Testing Important?
A1c testing is essential for several reasons:
- Diagnosing Prediabetes and Diabetes: An A1c test can help determine if you have prediabetes or diabetes, even before you experience any symptoms.
- Monitoring Diabetes Management: For individuals with diabetes, regular A1c tests help track how well their treatment plan is working. It allows doctors and patients to adjust medication, diet, and exercise as needed to maintain optimal blood sugar control.
- Predicting Risk of Complications: Consistently high A1c levels increase your risk of developing serious diabetes-related complications, such as heart disease, kidney disease, nerve damage (neuropathy), and eye damage (retinopathy). Maintaining healthy A1c levels can significantly reduce these risks.
How is A1c Measured?
The A1c test is a simple blood test, usually performed in a doctor's office or lab. No special preparation is required, such as fasting. The results are typically reported as a percentage. Here’s a breakdown of the common A1c ranges:
- Normal: Less than 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
It's important to remember that these are general guidelines, and your doctor may have slightly different target ranges based on your individual health needs and circumstances.
What A1c Levels Mean: A Detailed Explanation
Let's take a closer look at what each A1c range signifies:
-
A1c Below 5.7% (Normal): This indicates that your blood sugar levels are generally within the healthy range, and you don't have prediabetes or diabetes. Maintaining a healthy lifestyle through diet and exercise is still important to prevent future blood sugar issues.
-
A1c Between 5.7% and 6.4% (Prediabetes): This means you have prediabetes, a condition where your blood sugar levels are higher than normal but not yet high enough to be diagnosed as diabetes. People with prediabetes are at increased risk of developing type 2 diabetes. Lifestyle changes, such as weight loss, regular exercise, and a healthy diet, can often prevent or delay the onset of type 2 diabetes. In some cases, medication may also be recommended.
-
A1c of 6.5% or Higher (Diabetes): This confirms a diagnosis of diabetes. Your doctor will work with you to develop a comprehensive diabetes management plan, which may include medication, lifestyle changes, and regular blood sugar monitoring. The specific treatment approach will depend on the type of diabetes (type 1, type 2, or gestational) and your individual health needs.
A1c to eAG (Estimated Average Glucose) Conversion Chart
While A1c is reported as a percentage, it's helpful to understand how it relates to your estimated average glucose (eAG) levels, which are reported in mg/dL or mmol/L. This conversion allows you to better visualize your average blood sugar readings.
Here's an A1c to eAG conversion chart:
| A1c (%) | eAG (mg/dL) | eAG (mmol/L) |
|---|---|---|
| 6.0 | 126 | 7.0 |
| 6.5 | 140 | 7.8 |
| 7.0 | 154 | 8.6 |
| 7.5 | 169 | 9.4 |
| 8.0 | 183 | 10.2 |
| 8.5 | 197 | 11.0 |
| 9.0 | 212 | 11.8 |
| 9.5 | 226 | 12.6 |
| 10.0 | 240 | 13.4 |
| 10.5 | 255 | 14.2 |
| 11.0 | 269 | 15.0 |
| 11.5 | 283 | 15.8 |
| 12.0 | 298 | 16.6 |
Note: This chart provides estimated conversions. Individual results may vary slightly.
Factors that Can Affect A1c Test Results
While A1c is generally a reliable test, certain factors can affect the accuracy of the results:
- Anemia: Some types of anemia can falsely lower A1c levels.
- Hemoglobinopathies: Certain hemoglobin variants can interfere with the A1c test.
- Kidney Disease: Chronic kidney disease can affect A1c results.
- Pregnancy: A1c levels may be slightly lower during pregnancy.
If you have any of these conditions, be sure to inform your doctor, as they may need to use alternative methods to monitor your blood sugar control.
Managing Your A1c Levels
If your A1c levels are elevated, here are some strategies to help manage them:
- Follow a Healthy Diet: Focus on consuming whole, unprocessed foods, including plenty of fruits, vegetables, and whole grains. Limit your intake of sugary drinks, processed foods, and unhealthy fats. Consult with a registered dietitian 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. Regular exercise helps improve insulin sensitivity and lowers blood sugar levels.
- Take Medications as Prescribed: If you have diabetes, it's essential to take your medications exactly as prescribed by your doctor. Do not adjust your dosage without consulting them first.
- Monitor Your Blood Sugar Regularly: If you have diabetes, regular blood sugar monitoring can help you understand how different foods, activities, and medications affect your blood sugar levels. This information can help you make informed decisions about your diabetes management plan.
- Reduce Stress: Chronic stress can raise blood sugar levels. Find healthy ways to manage stress, such as meditation, yoga, or spending time in nature.
- Get Enough Sleep: Lack of sleep can also affect blood sugar control. Aim for 7-8 hours of quality sleep per night.
When to See a Doctor
- If you experience symptoms of diabetes: such as frequent urination, excessive thirst, unexplained weight loss, or blurred vision, consult your doctor to get tested.
- If you have risk factors for diabetes: such as a family history of diabetes, obesity, or gestational diabetes, talk to your doctor about getting screened.
- If you have prediabetes or diabetes: schedule regular appointments with your doctor to monitor your A1c levels and adjust your treatment plan as needed.
Conclusion
Understanding your A1c levels is a powerful tool for managing your health and preventing diabetes-related complications. By working closely with your doctor and making lifestyle changes, you can achieve and maintain healthy A1c levels and live a long and healthy life.

Follow along as @sonjakm, Chief of Staff at Levels, demonstrates how oat milk can cause a sharp rise in blood sugar. Sign Up to Get Your Ultimate Guide to Glucose: Blood sugar surges can sometimes lead to reactive hypoglycemia. That’s when a spike is followed by a steep drop in blood sugar, which can also make your energy drop. Common symptoms of reactive hypoglycemia: 🫠 Fatigue 😬 Shaking/jitters 🤢 Nausea 😤 Irritability 🙃 Difficulty focusing 😵💫 Dizziness Why does reactive hypoglycemia occur? A sharp rise in glucose signals pancreatic beta cells to produce and secrete insulin. Insulin acts like a key that unlocks cells so they can uptake glucose for energy. Therefore, a sudden increase in glucose can trigger a sudden surge in insulin. Cells then absorb the glucose, which in turn, lowers glucose levels in the bloodstream. Why can oat milk potentially spike blood sugar? Every person is different, meaning we all have different reactions to the same foods, and the same person can even react differently to the same food signs of high blood sugar spike at different times. However, we often see oat milk as a spiker on Levels data. Even if an oat milk is unsweetened, the nutrition label will list added sugars. That’s because during the manufacturing process, enzymes are added to break down oat starch so that the milk is creamy. The longer chains of oat carbohydrates are broken down into shorter chains of simple sugar like maltose. ☕️ What you can include how often do you test blood sugar in your latte To reduce the chances of reactive hypoglycemia, which can cause an energy slump, can you check blood sugar without pricking finger it may help to keep blood sugar levels more stable. Consider a nut milk (e.g., almond, cashew, or macadamia) or hemp, coconut, or flax milk. These all include minimal carbs while also including fat and protein. Fat and protein can help blunt a rise in blood sugar. Opt for unsweetened milk alternatives with as few ingredients as possible. One ingredient to avoid is carrageenan, which is linked to gastrointestinal inflammation (PMID: 34684400).
