Blood Sugar Levels Chart by Age: What Is a Normal Range for You?
Maintaining healthy blood sugar levels is crucial for overall well-being, and these levels can vary depending on your age, health conditions, and lifestyle. Understanding the normal ranges is the first step in preventing or managing diabetes and other related health issues. This article provides a comprehensive blood sugar levels chart by age, helping you understand what’s considered normal and what might indicate a problem.
Why Monitoring Blood Sugar Is Important
Blood sugar, or glucose, is the main sugar found in your blood and comes from the food you eat. Your body uses glucose for energy. Having consistently high or low blood sugar levels can lead to several health complications, including:
- Diabetes: Type 1, Type 2, and gestational diabetes.
- Heart disease: High blood sugar can damage blood vessels and increase the risk of cardiovascular problems.
- Kidney disease: Prolonged high blood sugar can harm the kidneys.
- Nerve damage (neuropathy): High blood sugar can affect nerve function, leading to pain, numbness, or tingling, especially in the hands and feet.
- Vision problems: Including blurred vision and an increased risk of cataracts and glaucoma.
Regular monitoring, especially for those at risk or diagnosed with diabetes, can help manage these risks and maintain a healthier life. This is where understanding a reliable blood sugar levels chart by age is vital.

Understanding Blood Sugar Measurements
Before diving into the chart, it’s essential to understand the common measurements used for blood sugar levels:
- mg/dL (milligrams per deciliter): This is the standard unit in the United States.
- mmol/L (millimoles per liter): This unit is used in many other countries.
The measurements are typically taken at different times:
- Fasting Blood Sugar (FBS): Measured after at least 8 hours of fasting (no food or drink).
- Postprandial Blood Sugar (PPBS): Measured 1-2 hours after a meal.
- HbA1c (Glycated Hemoglobin): This test provides an average of your blood sugar levels over the past 2-3 months. It does not require fasting.
- Random Blood Sugar (RBS): Measured at any time, regardless of when you last ate.
Blood Sugar Levels Chart by Age
Here's a general guideline for normal blood sugar levels by age. Note that these values are general and may vary slightly based on individual circumstances, lab standards, and specific medical advice. Always consult your healthcare provider for personalized recommendations.
| Age Group | Fasting Blood Sugar (mg/dL) | Postprandial Blood Sugar (mg/dL) (1-2 hours after eating) | HbA1c (%) |
|---|---|---|---|
| Children (Under 6 years old) | 80-180 mg/dL | Up to 180 mg/dL | 6.0-8.5% |
| Children (6-12 years old) | 80-120 mg/dL | Up to 140 mg/dL | Under 7.5% |
| Teenagers (13-19 years old) | 70-150 mg/dL | Up to 140 mg/dL | Under 7.0% |
| Adults (20+ years old) (Non-Diabetic) | 70-99 mg/dL | Up to 140 mg/dL | Under 5.7% |
| Adults (20+ years old) (Diabetic) | 80-130 mg/dL | Less than 180 mg/dL | Under 7.0% (As advised by doctor) |
| Older Adults (65+ years old) | 80-180 mg/dL | Up to 180 mg/dL | Under 7.5% (As advised by doctor) |
Specific Considerations by Age Group:
- Children (Under 6): Young children's blood sugar levels can fluctuate more than adults. Maintaining levels can be a challenge due to erratic eating habits and activity levels.
- Children and Teenagers (6-19): Growth spurts and hormonal changes can impact blood sugar. Consistent monitoring and communication with healthcare providers are vital, especially for those with type 1 diabetes.
- Adults (20+): For non-diabetic adults, maintaining blood sugar levels through a healthy diet and regular exercise is key. Diabetic adults should follow their healthcare provider’s recommendations for medication and lifestyle adjustments. Regular monitoring and adherence to a prescribed plan are crucial.
- Older Adults (65+): Older adults may have varying targets based on overall health and other medical conditions. Individualized goals are important to avoid hypoglycemia (low blood sugar), which can be particularly dangerous in this age group. This blood sugar levels chart by age can assist in ensuring they stay in the optimal range.
What to Do if Your Blood Sugar Is High
If your blood sugar levels are consistently high, it's essential to take action. Here are some steps you can take:
- Consult a Healthcare Provider: The first step is to seek professional medical advice. A doctor can diagnose any underlying conditions and recommend the appropriate treatment plan.
- Adjust Your Diet: Reduce your intake of sugary foods, refined carbohydrates, and unhealthy fats. Focus on a diet rich in fruits, vegetables, whole grains, and lean proteins.
- Increase Physical Activity: Regular exercise helps lower blood sugar levels and improves insulin sensitivity. Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Stay Hydrated: Drink plenty of water to help your kidneys flush out excess sugar.
- Monitor Blood Sugar Regularly: If you are already managing diabetes, closely monitor your blood sugar levels and adjust your medication as needed under the guidance of your doctor.
- Manage Stress: High stress levels can affect blood sugar. Practice stress-reducing activities like meditation, yoga, or spending time in nature.
What to Do if Your Blood Sugar Is Low
Low blood sugar, or hypoglycemia, can also be dangerous, especially for people with diabetes. Symptoms of low blood sugar can include shakiness, sweating, confusion, dizziness, and even loss of consciousness. If you experience these symptoms:
- Follow the 15-15 Rule: Eat or drink 15 grams of fast-acting carbohydrates, such as glucose tablets, fruit juice, or regular (non-diet) soda.
- Wait 15 Minutes: Check your blood sugar again after 15 minutes.
- Repeat if Necessary: If your blood sugar is still low, repeat the 15-15 rule.
- Eat a Meal or Snack: Once your blood sugar is back to normal, eat a meal or snack to prevent it from dropping again.
- Consult Your Doctor: If you experience frequent episodes of low blood sugar, consult your doctor to adjust your medication or treatment plan.

Preventative measures can go a long way in keeping your blood sugar levels within a healthy range. Here are some key strategies:
- Balanced Diet: Eat a well-balanced diet rich in fiber, lean protein, and healthy fats. Limit processed foods, sugary drinks, and excessive amounts of carbohydrates.
- Regular Exercise: Aim for at least 150 minutes of moderate-intensity exercise per week. Include both aerobic activities (like walking, running, or swimming) and strength training.
- Weight Management: Maintaining a healthy weight can improve insulin sensitivity and help regulate blood sugar levels.
- Adequate Sleep: Aim for 7-9 hours of quality sleep per night. Poor sleep can affect hormone levels that regulate blood sugar.
- Stress Management: Use relaxation techniques like meditation, deep breathing, or yoga to manage stress.
- Regular Monitoring: If you are at risk for diabetes or have been diagnosed with the condition, monitor your blood sugar levels regularly as directed by your healthcare provider.
The Role of Diet and Exercise
Diet and exercise are cornerstone components of managing and maintaining healthy blood sugar levels. What you eat directly impacts your glucose levels, and physical activity helps your body use insulin more effectively.
Diet:
- Focus on Fiber: High-fiber foods like whole grains, fruits, and vegetables slow the absorption of sugar, preventing spikes in blood sugar.
- Limit Sugary Drinks and Processed Foods: These can cause rapid increases in blood sugar levels.
- Choose Lean Proteins: Protein helps stabilize blood sugar and keeps you feeling full.
- Healthy Fats: Include sources like avocados, nuts, and olive oil, which support overall health.
Exercise:
- Improves Insulin Sensitivity: Making your cells more receptive to insulin, which helps lower blood sugar.
- Helps Manage Weight: Reducing your risk of insulin resistance.
- Increases Energy Levels: Promoting overall well-being and making it easier to stay active.
Conclusion
Understanding the blood sugar levels chart by age is an essential tool for managing and preventing diabetes and other health complications. By maintaining a healthy lifestyle, including a balanced diet, regular exercise, and regular monitoring, you can take proactive steps to keep your blood sugar levels within a normal range. Always consult your healthcare provider for personalized advice and guidance based on your individual needs and health status.
