What Is a Normal Blood Sugar Level? Charts by Age for Non-Diabetics
Understanding normal blood sugar levels is crucial for maintaining good health, especially for individuals without diabetes. While there's some variation depending on the source, general guidelines exist for healthy blood sugar ranges based on age. This article will provide detailed charts and insights into what constitutes a normal blood sugar level, helping you understand the significance of these measurements and how they relate to your overall health.
Why Monitoring Blood Sugar is Important
Even if you aren't diabetic, regularly checking and understanding your blood sugar levels can provide valuable insights into your body’s health. Maintaining stable blood sugar levels is essential for:
- Energy Levels: Stable blood sugar avoids energy crashes and keeps you feeling alert and focused.
- Mood Stability: Fluctuations can impact mood, leading to irritability and anxiety.
- Preventing Chronic Diseases: Prolonged spikes can increase the risk of developing insulin resistance and type 2 diabetes.
Understanding Blood Sugar Readings: Terms and Timing
Before diving into the charts, let's clarify some essential terms and timing related to blood sugar measurements:
- Fasting Blood Sugar: This is measured after an overnight fast (typically 8 hours or more). It’s a key indicator of how well your body regulates blood sugar overnight.
- Postprandial Blood Sugar: This is measured 1-2 hours after eating a meal. It indicates how well your body processes the glucose from food.
- mg/dL (Milligrams per Deciliter): This is the standard unit of measurement for blood sugar in the United States.
- mmol/L (Millimoles per Liter): This is the standard unit of measurement for blood sugar in many other countries.
Blood Sugar Charts by Age for Non-Diabetics (in mg/dL)
Here's a detailed look at what is generally considered a normal blood sugar level at different times of the day for non-diabetic individuals, categorized by age.

| Age Group | Fasting Blood Sugar (mg/dL) | 1-2 Hours After Eating (mg/dL) |
|---|---|---|
| Children (Under 6) | 80-180 | Up to 180 |
| Children (6-12) | 80-120 | Up to 140 |
| Teenagers (13-19) | 70-110 | Up to 140 |
| Adults (20+) | 70-100 | Up to 140 |
| Adults (65+) | 80-110 | Up to 140 |
Important Note: These values are general guidelines. Individual circumstances, medications, and overall health can affect these ranges. Always consult your healthcare provider for personalized advice.
Blood Sugar Levels: What's Considered Normal?
Let's break down these values further to understand what they mean for different age groups:
- Children (Under 6): This age group has a broader range due to less predictable eating patterns and activity levels. A normal blood sugar level for a child under 6 typically falls between 80 and 180 mg/dL.
- Children (6-12): As children become more regulated in their habits, the range tightens slightly. A normal blood sugar level is typically 80-120 mg/dL.
- Teenagers (13-19): Teenagers experience hormonal changes that can impact blood sugar. The normal blood sugar range aligns more closely with adults: 70-110 mg/dL.
- Adults (20+): For most adults, a normal fasting blood sugar is between 70-100 mg/dL, and postprandial blood sugar should not exceed 140 mg/dL.
- Older Adults (65+): Older adults might have slightly higher normal blood sugar levels due to decreased insulin sensitivity, but still generally adhere to values close to the adult range.
Factors Affecting Blood Sugar Levels in Non-Diabetics
Several factors can influence blood sugar levels in people without diabetes:
- Diet: Consuming sugary drinks or large amounts of refined carbohydrates can lead to temporary spikes in blood sugar.
- Physical Activity: Exercise helps lower blood sugar levels as it makes your cells more sensitive to insulin.
- Stress: Stress hormones can cause the liver to release stored glucose, increasing blood sugar.
- Medications: Some medications, like corticosteroids, can affect blood sugar levels.
- Dehydration: Dehydration can lead to higher blood sugar concentration.
What to Do If Your Blood Sugar Is Consistently High (Even Without Diabetes)
If you consistently experience high blood sugar levels even without diabetes, it’s important to take action. Here are some steps to consider:
- Consult Your Healthcare Provider: They can run tests to determine the cause and provide personalized advice.
- Review Your Diet: Focus on whole, unprocessed foods and limit sugary drinks and refined carbs. A balanced diet is key.
- Increase Physical Activity: Aim for at least 30 minutes of moderate-intensity exercise most days of the week. Regular exercise has substantial benefits.
- Manage Stress: Practice stress-reducing techniques like meditation, yoga, or deep breathing exercises. Stress management is vital.
- Monitor Regularly: Keep track of your blood sugar levels using a home glucose monitor, and share the results with your doctor.
