Is Your Fasting Blood Sugar in the Normal Range? A Chart by Age
Understanding your fasting blood sugar levels is a crucial part of managing your overall health, particularly in the context of preventing or managing diabetes. This article provides a comprehensive look at what normal fasting blood sugar ranges are, how they vary by age, and what to do if your results fall outside the healthy zone. We'll cover everything from how to prepare for a fasting blood glucose test to potential next steps based on your readings.
What is Fasting Blood Sugar?
Fasting blood sugar (FBS) refers to the glucose level in your blood after you haven't eaten or had any caloric intake for at least eight hours. Measuring FBS is a common way to screen for prediabetes and diabetes. The test is usually performed in the morning before you’ve had breakfast. Because your body has had time to process any food you've previously consumed, a fasting blood glucose test gives a baseline indication of how well your body regulates glucose.
Why is Fasting Blood Sugar Important?
Monitoring fasting blood sugar is essential for several reasons:
- Early Detection of Diabetes: High FBS levels may indicate that your body isn't producing enough insulin or isn't using it effectively, which are hallmarks of type 2 diabetes.
- Prediabetes Screening: Elevated FBS levels that are not yet high enough to be classified as diabetes may indicate prediabetes, giving you a window of opportunity to make lifestyle changes to prevent the progression to diabetes.
- Management of Existing Diabetes: For individuals already diagnosed with diabetes, regularly monitoring FBS helps them adjust medication and dietary habits to maintain optimal blood sugar levels.
- Assessing Insulin Sensitivity: Fasting blood sugar levels can also provide insights into insulin resistance, which is a condition where the body's cells don't respond normally to insulin.
Normal Fasting Blood Sugar Ranges by Age: Chart and Explanation
While general guidelines exist for normal fasting blood sugar, levels can slightly vary based on age. Below is a table summarizing these ranges:
| Age Group | Normal Fasting Blood Sugar (mg/dL) | Prediabetes (mg/dL) | Diabetes (mg/dL) |
|---|---|---|---|
| Children (6-12 years) | 70-100 | 101-125 | 126 or higher |
| Teenagers (13-19 years) | 70-100 | 101-125 | 126 or higher |
| Adults (20-59 years) | 70-99 | 100-125 | 126 or higher |
| Older Adults (60+ years) | 80-110 | 111-125 | 126 or higher |
Important Considerations:
- These ranges are general guidelines. Your doctor may have specific targets based on your health history.
- mg/dL stands for milligrams per deciliter, the standard unit for measuring blood sugar.
- Older adults sometimes have slightly higher acceptable ranges due to age-related physiological changes.
How to Prepare for a Fasting Blood Sugar Test
Proper preparation ensures accurate fasting blood sugar results. Here’s how to get ready:
- Fast for at Least 8 Hours: Avoid eating or drinking anything (except water) for at least eight hours before the test. Usually, you’ll be instructed to fast overnight and have the test done first thing in the morning.
- Inform Your Doctor About Medications: Some medications can affect blood sugar levels. Discuss all medications and supplements you are taking with your doctor.
- Avoid Strenuous Exercise: Refrain from intense physical activity the day before the test, as it can influence blood sugar readings.
- Stay Hydrated: Drink water to stay hydrated, as dehydration can affect blood glucose levels.
- Follow Instructions Carefully: Listen to and follow your healthcare provider's specific instructions.

Interpreting your fasting blood sugar levels involves understanding the different categories and what they mean for your health.
Normal Range
A normal fasting blood sugar level is generally between 70 and 99 mg/dL for adults. This indicates that your body is effectively regulating glucose levels.
Prediabetes
Prediabetes is diagnosed when FBS levels range from 100 to 125 mg/dL. This signifies that your blood sugar is higher than normal, but not yet high enough to be classified as diabetes. Prediabetes is a critical stage because lifestyle changes can often prevent the development of type 2 diabetes.
Diabetes
Diabetes is indicated by fasting blood sugar levels of 126 mg/dL or higher on two separate tests. This means your body is not producing enough insulin or is not using it effectively to regulate blood glucose levels. Further evaluation and treatment will be necessary.
What to Do if Your Fasting Blood Sugar is High
If your fasting blood sugar readings are high, it’s essential to take appropriate action:
- Consult Your Doctor: The first step is to consult with your healthcare provider. They can review your results, assess your overall health, and provide personalized recommendations.
- Follow Medical Advice: Adhere to any medical advice, which might include further testing (like an A1C test), lifestyle modifications, or medication.
- Make Lifestyle Changes: Implement healthy lifestyle changes such as adopting a balanced diet, engaging in regular physical activity, and maintaining a healthy weight.
- Monitor Regularly: If you have prediabetes or diabetes, consistent monitoring of your blood sugar levels is crucial to manage your condition effectively.
Lifestyle Changes to Improve Fasting Blood Sugar
Even if your fasting blood sugar is within the prediabetic range, adopting lifestyle changes can help improve your blood sugar control and overall health:

- Balanced Diet: Focus on a diet rich in fruits, vegetables, whole grains, and lean proteins. Limit sugary drinks, processed foods, and saturated fats.
- Regular Exercise: Aim for at least 150 minutes of moderate-intensity exercise per week. This could include brisk walking, cycling, or swimming.
- Weight Management: Losing even a small amount of weight (5-10% of your body weight) can significantly improve blood sugar levels.
- Stress Management: Chronic stress can elevate blood sugar levels. Incorporate stress-reducing activities such as yoga, meditation, or deep breathing exercises.
- Adequate Sleep: Aim for 7-9 hours of quality sleep each night. Lack of sleep can affect insulin sensitivity.
The Importance of Regular Check-Ups
Regardless of your age or current health status, regular check-ups and blood sugar screenings are crucial. These screenings help in early detection, timely intervention, and effective management of blood sugar levels. People with a family history of diabetes, those who are overweight, or individuals with other risk factors should be particularly vigilant about their fasting blood sugar.
By understanding what constitutes a normal fasting blood sugar level for your age, how to prepare for a test, and what actions to take based on the results, you can proactively manage your health and potentially prevent or delay the onset of diabetes. Always consult with your healthcare provider for personalized advice and treatment options.
