The Prediabetes Range: Are You at Risk? What to Do Next

04 Sep 2025 by Gregory W. Barsness, M.D.

The Prediabetes Range: Are You at Risk? What to Do Next

Prediabetes is a health 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 – a chance to take action and prevent the development of full-blown type 2 diabetes. Many people with prediabetes don't even know they have it, as it often has no obvious symptoms. But understanding the prediabetes range, identifying your risk factors, and knowing what to do next are vital steps toward a healthier future.

Understanding the Prediabetes Range

So, what exactly is the prediabetes range? Doctors use blood tests to determine where you fall on the spectrum. Here are the key numbers to understand:

  • Fasting Plasma Glucose (FPG): This test measures your blood sugar after an overnight fast. Hyperglycemia Vs Hypoglycemia Know The Critical Difference

    • Normal: Less than 100 mg/dL
    • Prediabetes: 100 to 125 mg/dL
    • Diabetes: 126 mg/dL or higher
  • A1C Test: This test measures your average blood sugar levels over the past 2-3 months.

    • Normal: Less than 5.7%
    • Prediabetes: 5.7% to 6.4%
    • Diabetes: 6.5% or higher
  • Oral Glucose Tolerance Test (OGTT): This test measures your blood sugar two hours after drinking a special sugary drink. While less commonly used for initial screening, it can be helpful.

    • Normal: Less than 140 mg/dL
    • Prediabetes: 140 to 199 mg/dL
    • Diabetes: 200 mg/dL or higher

If any of these tests fall within the prediabetes range, it's important to discuss the results with your doctor. A single high result doesn't necessarily mean you have prediabetes, but it's a reason to investigate further.

Are You at Risk? Risk Factors for Prediabetes

Several factors can increase your risk of developing prediabetes. Being aware of these risk factors can help you take proactive steps to protect your health.

  • Weight: Being overweight or obese significantly increases your risk. Excess weight, particularly around the abdomen, is associated with insulin resistance.
  • Inactivity: A sedentary lifestyle contributes to insulin resistance. Regular physical activity helps your body use insulin more effectively.
  • Family History: Having a parent, sibling, or other close relative with type 2 diabetes increases your risk.
  • Age: The risk of prediabetes increases with age, particularly after age 45.
  • Race/Ethnicity: Certain racial and ethnic groups, including African Americans, Hispanic/Latino Americans, American Indians, Pacific Islanders, and some Asian Americans, have a higher risk.
  • Gestational Diabetes: Having gestational diabetes (diabetes during pregnancy) increases your risk of developing prediabetes and type 2 diabetes later in life.
  • Polycystic Ovary Syndrome (PCOS): Women with PCOS are at a higher risk of prediabetes due to insulin resistance.
  • Sleep Problems: Sleep apnea and other sleep disturbances can contribute to insulin resistance.
  • Certain Medications: Some medications, such as steroids, can increase blood sugar levels and contribute to prediabetes.

Knowing your risk factors is the first step. If you have several of these factors, it's even more crucial to get screened for prediabetes.

What to Do Next: Taking Control of Your Health

The good news is that prediabetes is often reversible with lifestyle changes. Taking action now can significantly reduce your risk of developing type 2 diabetes and improve your overall health. How To Manage Blood Sugar A Complete Lifestyle Guide For Beginners

  1. Get Tested: If you have risk factors for prediabetes, talk to your doctor about getting tested. Regular screenings are essential for early detection.
  2. Dietary Changes: Focus on a healthy, balanced diet rich in fruits, vegetables, and whole grains.
    • Reduce Added Sugars: Limit sugary drinks, processed foods, and desserts.
    • Increase Fiber Intake: Choose whole grains, fruits, and vegetables to increase your fiber intake.
    • Control Portion Sizes: Be mindful of portion sizes to help manage your weight.
  3. Increase Physical Activity: Aim for at least 150 minutes of moderate-intensity aerobic exercise per week, such as brisk walking. Also, incorporate strength training exercises at least twice a week.
  4. Lose Weight: Even losing a small amount of weight (5-7% of your body weight) can significantly reduce your risk of developing type 2 diabetes.
  5. Quit Smoking: Smoking increases your risk of prediabetes and numerous other health problems.
  6. Manage Stress: Chronic stress can affect blood sugar levels. Find healthy ways to manage stress, such as exercise, meditation, or spending time in nature.
  7. Medication: In some cases, your doctor may recommend medication, such as metformin, to help prevent type 2 diabetes. This is typically reserved for people at very high risk.
  8. Regular Check-ups: Once you've been diagnosed with prediabetes, it's important to have regular check-ups with your doctor to monitor your blood sugar levels and make any necessary adjustments to your treatment plan.

Monitoring Your Progress

It's important to track your progress as you make lifestyle changes. This can help you stay motivated and identify areas where you may need to adjust your approach. Keep a food journal, track your physical activity, and monitor your weight regularly. Share this information with your doctor to get personalized feedback and support.

Success Stories and Inspiration

Many people have successfully reversed prediabetes through lifestyle changes. Reading their stories can provide inspiration and motivation. Look for online communities or support groups where you can connect with others who are on a similar journey. Sharing experiences and tips can be invaluable as you work toward a healthier future.

Key Takeaways

Prediabetes is a serious condition, but it's also an opportunity. By understanding the prediabetes range, recognizing your risk factors, and taking proactive steps to improve your health, you can significantly reduce your risk of developing type 2 diabetes and live a longer, healthier life.

Prediabetes Risk Factors and Recommended Actions (HTML Table Example)

Risk Factor Explanation Recommended Action
Overweight/Obesity Excess weight, especially around the abdomen, contributes to **insulin resistance**. Aim for a healthy weight through diet and exercise. Even modest weight loss (5-7%) can make a big difference.
Inactivity A sedentary lifestyle contributes to **insulin resistance** and poor blood sugar control. Engage in at least 150 minutes of moderate-intensity aerobic exercise per week, such as brisk walking.
Family History Having a close relative with type 2 diabetes increases your genetic predisposition. Get screened for prediabetes and adopt healthy lifestyle habits to mitigate your risk.
Age (45+) The risk of prediabetes increases with age due to natural physiological changes. Be vigilant about maintaining a healthy lifestyle and getting regular check-ups.
Gestational Diabetes Having gestational diabetes during pregnancy increases your risk of developing prediabetes later. Follow up with your doctor after pregnancy to get screened for prediabetes and manage your risk factors.
