What is Prediabetes? Understanding Your A1c and Fasting Sugar Levels
Prediabetes is a condition where your blood sugar levels are higher than normal but not high enough to be diagnosed as type 2 diabetes. Think of it as a warning sign – your body is starting to have trouble processing glucose (sugar), and if you don't take action, you could develop type 2 diabetes. Understanding what prediabetes is, how it's diagnosed using A1c and fasting sugar levels, and what you can do about it, are crucial steps toward a healthier future.
Understanding Prediabetes: A Wake-Up Call
Prediabetes often has no clear symptoms, making it essential to get screened, especially if you have risk factors such as being overweight, having a family history of diabetes, being physically inactive, or having certain ethnic backgrounds (African American, Hispanic, Native American, Asian American, and Pacific Islander). Identifying prediabetes gives you the opportunity to make lifestyle changes that can prevent or delay the onset of type 2 diabetes. These changes can include diet modifications, increased physical activity, and weight management. The key here is early detection and intervention. Don’t ignore this wake-up call; take control of your health.
A1c: Your Average Blood Sugar Over Time
The A1c test, also known as the hemoglobin A1c test, measures your average blood sugar levels over the past 2-3 months. It works by measuring the percentage of your hemoglobin that is coated with sugar (glucose). This test gives a broader picture of your blood sugar control compared to a single fasting blood sugar test.

- Normal A1c: Below 5.7%
- Prediabetes A1c: 5.7% to 6.4%
- Diabetes A1c: 6.5% or higher
A reading in the prediabetes range means that your blood sugar levels have been consistently higher than normal over the past few months. It’s important to note that A1c results can be affected by certain medical conditions, such as anemia or kidney disease. Talk to your doctor to understand your A1c result in the context of your overall health.
Fasting Sugar Levels: A Snapshot of Your Blood Sugar
A fasting plasma glucose (FPG) test measures your blood sugar levels after you haven’t eaten or drank anything (except water) for at least eight hours. This test provides a snapshot of your blood sugar levels at a specific point in time.
- Normal Fasting Sugar: Less than 100 mg/dL
- Prediabetes Fasting Sugar: 100 to 125 mg/dL
- Diabetes Fasting Sugar: 126 mg/dL or higher

A fasting sugar level in the prediabetes range suggests that your body is having trouble regulating blood sugar overnight. This could be due to insulin resistance, where your cells don't respond well to insulin, a hormone that helps glucose enter cells for energy.
A1c vs. Fasting Sugar: Which Test is Best?
Both the A1c and fasting plasma glucose tests are used to diagnose prediabetes and diabetes. However, they provide different information. The A1c test gives an average blood sugar level over several months, while the fasting glucose test gives a snapshot in time. The A1c test doesn't require fasting, making it more convenient for some people. Many doctors use both tests, or may prefer one over the other, based on individual patient factors. Consult with your healthcare provider to determine which test, or combination of tests, is most appropriate for you.
Risk Factors for Prediabetes
Knowing the risk factors can help you assess your likelihood of developing prediabetes:
- Weight: Being overweight or obese significantly increases your risk.
- Family History: Having a parent, sibling, or close relative with type 2 diabetes increases your risk.
- Age: The risk of prediabetes increases with age, especially after age 45.
- Physical Inactivity: Being less active increases your risk.
- Gestational Diabetes: Having gestational diabetes during pregnancy or giving birth to a baby weighing more than 9 pounds increases your risk.
- Polycystic Ovary Syndrome (PCOS): Women with PCOS have a higher risk.
- Race/Ethnicity: As mentioned earlier, certain ethnic groups have a higher risk.
- Sleep Apnea: This condition can increase insulin resistance.
Addressing these risk factors can dramatically reduce your chances of progressing from prediabetes to type 2 diabetes.
Taking Action: Steps to Reverse Prediabetes
The good news is that prediabetes can often be reversed through lifestyle changes. Here are some actionable steps you can take:

- Diet Modifications: Focus on eating a healthy, balanced diet that includes plenty of fruits, vegetables, and whole grains. Limit processed foods, sugary drinks, and saturated and trans fats.
- Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity aerobic exercise each week. This could include brisk walking, jogging, swimming, or cycling.
- Weight Management: Losing even a small amount of weight (5-7% of your body weight) can make a big difference.
- Stress Management: Chronic stress can raise blood sugar levels. Practice relaxation techniques such as yoga, meditation, or deep breathing exercises.
- Regular Check-ups: Continue to monitor your blood sugar levels with regular check-ups. Your doctor may recommend repeat A1c or fasting glucose tests to track your progress.
- Medications: In some cases, your doctor may prescribe medications, such as metformin, to help lower your blood sugar levels. This is usually considered when lifestyle changes alone are not enough.
Monitoring Your Progress
Regular monitoring of your blood sugar levels and A1c is crucial to tracking your progress and making adjustments to your lifestyle changes as needed. Keeping a log of your blood sugar readings, diet, and physical activity can help you identify patterns and make informed decisions about your health. Work closely with your healthcare team, including your doctor, a registered dietitian, and a certified diabetes educator, to develop a personalized plan that works for you.
Impact of Lifestyle Changes on A1c Levels
Here's a breakdown of how specific lifestyle changes can impact your A1c levels:
| Lifestyle Change | Expected Impact on A1c | Additional Benefits |
|---|---|---|
| Dietary Changes (Reduced sugar intake) | Possible reduction of 0.5% to 1% in A1c | Weight loss, improved cholesterol levels, increased energy |
| Increased Physical Activity (150 minutes/week) | Possible reduction of 0.3% to 0.7% in A1c | Improved cardiovascular health, stronger bones, reduced stress |
| Weight Loss (5-7% of body weight) | Possible reduction of 0.5% to 1% in A1c | Reduced risk of heart disease, improved mobility, better sleep |
These figures are estimates, and individual results may vary. Consistent effort and adherence to a healthy lifestyle are key to achieving the best possible outcomes.
Prediabetes and the Risk of Developing Type 2 Diabetes
Prediabetes is a significant risk factor for developing type 2 diabetes. However, it’s not an inevitable outcome. Studies have shown that lifestyle interventions can significantly reduce the risk of progressing from prediabetes to type 2 diabetes. The Diabetes Prevention Program (DPP), for example, found that lifestyle changes reduced the risk of developing type 2 diabetes by 58% over three years, compared to a placebo group.
Don’t wait for symptoms to appear. Talk to your doctor about getting screened for prediabetes, especially if you have risk factors. By understanding your A1c and fasting sugar levels, and taking proactive steps to manage your health, you can significantly reduce your risk of developing type 2 diabetes and improve your overall well-being.
