Is Your Fasting Blood Sugar in the Prediabetes Range? What to Do Next

04 Sep 2025 by Sydney A. Westphal, M.D.

Is Your Fasting Blood Sugar in the Prediabetes Range? What to Do Next

If you've recently had your fasting blood sugar tested and the results came back indicating that you're in the prediabetes range, it's essential to understand what this means and, more importantly, what you can do about it. Prediabetes is a condition where your blood sugar levels are higher than normal, but not yet high enough to be diagnosed as type 2 diabetes. Think of it as a warning sign—a chance to take control of your health and potentially prevent the development of full-blown diabetes.

Understanding Fasting Blood Sugar and Prediabetes

Before diving into the "what to do next," let's clarify what fasting blood sugar is and how it relates to prediabetes.

  • Fasting Blood Sugar: This is a blood sugar test taken after an overnight fast (typically at least 8 hours of no food or drink, except water). It provides a baseline measure of your blood sugar level.

  • Normal Fasting Blood Sugar: Generally, a normal fasting blood sugar is considered to be between 70 mg/dL and 99 mg/dL.

  • Prediabetes Range: A fasting blood sugar between 100 mg/dL and 125 mg/dL typically indicates prediabetes. Decoding The Blood Sugar Levels Chart What S Normal By Age

  • Diabetes Range: A fasting blood sugar of 126 mg/dL or higher on two separate tests usually indicates diabetes.

It’s important to remember that these ranges can slightly vary depending on the lab, so it's crucial to discuss your results with your doctor.

What To Do If Your Fasting Blood Sugar Is in the Prediabetes Range

Okay, so your results are back, and you’re in that gray area. Don’t panic! Prediabetes is often reversible with lifestyle changes. Here’s a comprehensive guide to what you should do next:

  1. Consult with Your Doctor: This is the most crucial first step. Discuss your results with your physician. They can confirm the diagnosis, rule out other potential causes for elevated blood sugar, and provide personalized advice based on your health history and individual needs. Ask them if further testing (such as an A1C test or an oral glucose tolerance test) is needed.

  2. Adopt a Healthier Diet: Your diet plays a major role in blood sugar control. Focus on the following:

    • Reduce Sugar and Refined Carbs: Limit your intake of sugary drinks, processed foods, white bread, pastries, and other sources of refined carbohydrates. These foods cause rapid spikes in blood sugar levels.
    • Increase Fiber Intake: Fiber helps regulate blood sugar levels. Good sources of fiber include fruits, vegetables, whole grains, and legumes.
    • Choose Complex Carbohydrates: Opt for whole grains like quinoa, brown rice, and oats over processed grains.
    • Lean Protein: Include lean protein sources like chicken breast, fish, beans, and tofu in your meals. Protein helps you feel fuller for longer and can aid in blood sugar control.
    • Healthy Fats: Incorporate healthy fats like avocados, nuts, seeds, and olive oil into your diet.
  3. Increase Physical Activity: Exercise is incredibly beneficial for blood sugar control. It improves your body's ability to use insulin and lowers blood sugar levels.

    • Aim for at Least 150 Minutes of Moderate-Intensity Exercise Per Week: This could include brisk walking, jogging, swimming, or cycling.
    • Include Strength Training: Strength training helps build muscle mass, which improves insulin sensitivity. Aim for strength training exercises at least twice a week.
    • Break Up Sedentary Time: Even short bursts of activity throughout the day can make a difference. Take the stairs instead of the elevator, walk during your lunch break, or do some simple stretches every hour.
  4. Lose Weight (If Necessary): If you are overweight or obese, losing even a small amount of weight (5-7% of your body weight) can significantly reduce your risk of developing type 2 diabetes. Focus on making sustainable lifestyle changes rather than following fad diets.

  5. Monitor Your Blood Sugar Regularly: Your doctor may recommend monitoring your blood sugar levels at home using a glucometer.

  6. Manage Stress: Stress can significantly impact blood sugar levels. Find healthy ways to manage stress, such as yoga, meditation, spending time in nature, or engaging in hobbies you enjoy. Normal Blood Sugar After Eating What To Expect And When To Worry

  7. Get Enough Sleep: Lack of sleep can disrupt hormones that regulate blood sugar levels. Aim for 7-8 hours of quality sleep per night.

  8. Consider Medications (If Recommended by Your Doctor): In some cases, your doctor may recommend medication, such as metformin, to help lower your blood sugar levels. Medication is often prescribed in conjunction with lifestyle changes.

Tracking Your Progress

Keeping track of your progress is key to staying motivated and making necessary adjustments. Here's an example of metrics you might track:

Metric How to Track Target
Fasting Blood Sugar Home glucometer (as directed by your doctor) or lab tests. Below 100 mg/dL
Weight Regular weigh-ins (weekly or bi-weekly). 5-7% weight loss (if overweight)
Physical Activity Exercise tracker, calendar. 150 minutes of moderate intensity exercise per week
A1C Lab Test (every 3-6 months, as recommended by your doctor) Below 5.7%

The Importance of Consistency

It's crucial to understand that managing prediabetes is a long-term commitment. Making these lifestyle changes consistently is key to preventing the progression to type 2 diabetes. There will be challenges along the way, but stay focused on your goals and celebrate your successes.

The Takeaway: You Are in Control

Having a fasting blood sugar in the prediabetes range is a wake-up call, but it’s also an opportunity. By taking proactive steps to improve your diet, increase physical activity, manage stress, and get enough sleep, you can significantly reduce your risk of developing type 2 diabetes and improve your overall health and well-being. Don't delay – start making changes today. Consult your doctor and begin your journey to a healthier future. Remember, you have the power to take control of your health!
