What Are Normal Blood Sugar Levels? The Definitive Chart by Age
Understanding normal blood sugar levels is crucial for maintaining overall health and preventing diabetes-related complications. Blood sugar, or glucose, is the primary source of energy for your body, and keeping it within a healthy range is essential. This article provides a definitive chart of normal blood sugar levels by age, along with helpful insights on how to manage your glucose levels effectively.
Why Blood Sugar Levels Matter
Maintaining stable blood sugar levels is vital for several reasons:
- Energy Levels: Balanced glucose provides consistent energy, preventing fatigue and mood swings.
- Organ Function: Organs like the brain, heart, and kidneys rely on a steady supply of glucose to function correctly.
- Diabetes Prevention: Monitoring and managing blood sugar can help prevent type 2 diabetes.
- Complication Reduction: For those with diabetes, maintaining target levels reduces the risk of long-term complications such as nerve damage, kidney disease, and heart problems.
Understanding Blood Sugar Readings
Before diving into the chart, let's clarify the units of measurement commonly used:
- mg/dL (milligrams per deciliter): The standard unit in the United States.
- mmol/L (millimoles per liter): Used in many other countries.
Also, it's important to know the different times when blood sugar levels are measured:

- Fasting Blood Sugar: Measured after at least eight hours of not eating.
- Before Meal: Measured just before consuming a meal.
- After Meal (Postprandial): Typically measured one to two hours after starting a meal.
- HbA1c: Reflects average blood sugar levels over the past 2-3 months.
The Definitive Blood Sugar Level Chart by Age
Below is a comprehensive chart detailing normal blood glucose levels for different age groups, including specific considerations for those with and without diabetes. Please remember that these are general guidelines and individual targets may vary based on a healthcare provider's recommendations.
| Age Group | Fasting Blood Sugar (mg/dL) | Before Meal (mg/dL) | 1-2 Hours After Meal (mg/dL) | HbA1c (%) |
|---|---|---|---|---|
| Children (Under 6 years) - Without Diabetes | 80-180 | 100-180 | 110-200 | N/A |
| Children (6-12 years) - Without Diabetes | 70-120 | 70-120 | Up to 140 | N/A |
| Teens (13-19 years) - Without Diabetes | 70-100 | 70-100 | Up to 140 | N/A |
| Adults (20+ years) - Without Diabetes | 70-100 | 70-100 | Up to 140 | Below 5.7% |
| Adults (20+ years) - With Diabetes | 80-130 | 80-130 | Less than 180 | Below 7.0% (as advised by doctor) |
| Elderly (65+ years) - Without Diabetes | 80-110 | 80-110 | Up to 160 | Below 6.5% |
| Elderly (65+ years) - With Diabetes | 90-150 | 90-150 | Less than 200 | Below 8.0% (as advised by doctor) |
Key Considerations for Different Age Groups
- Children: Maintaining stable blood sugar in children is particularly important for their growth and development. Fluctuations can affect energy levels and behavior. Parents should work closely with pediatricians and endocrinologists.
- Teens: Hormonal changes during adolescence can impact blood sugar control. Education on healthy eating habits and the importance of physical activity is essential.
- Adults: Adults should monitor their blood glucose levels regularly, especially if they have risk factors for diabetes such as obesity, family history, or sedentary lifestyle.
- Elderly: Older adults may have different blood sugar targets. A1c goals are often more lenient in the elderly to prevent hypoglycemia (low blood sugar), which can be dangerous.
Factors Influencing Blood Sugar Levels
Several factors can affect your blood sugar, including:
- Diet: Carbohydrates, especially refined sugars and processed foods, can cause rapid spikes in blood sugar.
- Physical Activity: Exercise helps lower blood sugar by increasing insulin sensitivity and utilizing glucose for energy.
- Stress: Stress hormones can raise blood sugar levels.
- Medications: Certain medications, such as steroids and some antidepressants, can affect glucose levels.
- Illness: Infections and other illnesses can cause blood sugar levels to fluctuate.
- Hydration: Dehydration can affect blood sugar concentration.

- Manage Stress: Practice stress-reducing techniques such as meditation, yoga, or deep breathing exercises.
- Medication Adherence: If you have diabetes, take your medications as prescribed by your doctor.
Symptoms of High and Low Blood Sugar
Recognizing the symptoms of both high and low blood sugar is essential for timely management:
Hyperglycemia (High Blood Sugar):
- Increased thirst
- Frequent urination
- Blurred vision
- Fatigue
- Slow-healing sores
Hypoglycemia (Low Blood Sugar):
- Shakiness
- Sweating
- Dizziness
- Confusion
- Hunger
- Irritability
If you experience any of these symptoms, check your blood sugar immediately and take appropriate action, such as eating a quick-acting carbohydrate for low blood sugar or contacting your healthcare provider for high blood sugar.
When to Seek Medical Advice
It’s crucial to consult a healthcare provider if:
- You experience frequent episodes of high or low blood sugar.
- You have symptoms of diabetes.
- You are at risk for diabetes and want to get tested.
- You need help managing your blood sugar levels.
Advanced Blood Sugar Monitoring: CGM (Continuous Glucose Monitoring)
Continuous Glucose Monitoring (CGM) systems have revolutionized diabetes management. These devices track blood sugar levels in real-time, providing valuable data to help you make informed decisions about your diet, exercise, and medication. CGMs can alert you to highs and lows, helping to prevent dangerous fluctuations.
