Normal Blood Sugar Levels: A Chart by Age for Non-Diabetics
Understanding normal blood sugar levels is crucial for maintaining good health, especially if you're at risk of developing diabetes or simply want to monitor your well-being. This article provides a comprehensive overview of normal blood glucose ranges for non-diabetic individuals across different age groups. We’ll break down the numbers, discuss factors that influence blood sugar, and outline when it might be time to consult a healthcare professional. Let's dive in!
What is Blood Sugar and Why Does It Matter?
Blood sugar, also known as blood glucose, refers to the amount of glucose present in your blood. Glucose is a primary source of energy for your body, derived from the food you eat. Insulin, a hormone produced by the pancreas, helps glucose enter cells to be used for energy.
Maintaining stable blood sugar levels is vital because:

These values typically apply to individuals who do not have diabetes. They are based on guidelines from medical organizations and can serve as a general reference. Keep in mind that individual results can vary slightly, and it’s always best to consult with a healthcare professional for personalized advice.
| Age Group | Fasting Blood Sugar (mg/dL) | 2 Hours After Eating (mg/dL) |
|---|---|---|
| Children (Under 6) | 80-180 | Up to 200 |
| Children (6-12) | 70-150 | Up to 180 |

- Fasting Blood Sugar: Measured after at least 8 hours of fasting (usually overnight).
- 2 Hours After Eating: Measured approximately two hours after the start of a meal.
Factors Influencing Blood Sugar Levels
Several factors can influence blood glucose readings, even in individuals without diabetes:
- Diet: The type and amount of carbohydrates consumed have the most significant impact.
- Physical Activity: Exercise helps lower blood sugar by increasing insulin sensitivity and glucose uptake by muscles.
- Stress: Stress hormones can raise blood sugar levels.
- Sleep: Insufficient sleep can impair insulin sensitivity.
- Medications: Some medications, like steroids, can elevate blood sugar.
- Illness: Infections can cause fluctuations in blood sugar.
- Age: As you age, insulin resistance can increase slightly.
- Hydration: Dehydration can affect blood sugar concentration.
Symptoms of High and Low Blood Sugar
Even in non-diabetics, significant fluctuations in blood sugar levels can cause symptoms. While extreme symptoms are rare, being aware of these signs is helpful:
High Blood Sugar (Hyperglycemia) Symptoms:
- Increased thirst
- Frequent urination
- Blurred vision

When to See a Doctor
It’s essential to seek medical advice if you experience any of the following:
- Consistently high or low blood sugar levels outside the ranges specified in the chart.
- Frequent symptoms of hyperglycemia or hypoglycemia.
- A family history of diabetes, combined with risk factors such as obesity or a sedentary lifestyle.
- If you're pregnant or planning to become pregnant (gestational diabetes risk).
A healthcare professional can perform tests, such as an A1C test, to assess your average blood sugar levels over the past 2-3 months and determine if you’re at risk for diabetes or other health issues.
Tips for Maintaining Healthy Blood Sugar Levels
Even if you're not diabetic, proactive management can keep your blood sugar within a healthy range:
- Balanced Diet: Focus on whole grains, lean proteins, and plenty of fruits and vegetables. Limit processed foods and sugary drinks.
- Regular Exercise: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Stay Hydrated: Drink plenty of water throughout the day.
- Manage Stress: Practice relaxation techniques such as yoga, meditation, or deep breathing.
- Prioritize Sleep: Aim for 7-9 hours of quality sleep each night.
- Regular Check-ups: Get regular health screenings, including blood sugar checks, as recommended by your doctor.
The Importance of Blood Sugar Monitoring
While frequent monitoring may not be necessary for all non-diabetics, individuals with risk factors (such as family history, obesity, or prediabetes) may benefit from occasional blood sugar testing to monitor their levels and identify potential issues early.
Conclusion
Understanding normal blood sugar levels and the factors that influence them is essential for maintaining good health and preventing diabetes. By following a healthy lifestyle, monitoring your blood sugar when appropriate, and consulting with a healthcare professional, you can ensure your blood glucose remains within a healthy range. Remember that these blood sugar ranges provide a general guideline. Always consult with your physician for personalized medical advice. Keeping an eye on your blood sugar levels is a proactive step towards a healthier you.
