Normal Blood Sugar Levels by Age: A Complete Chart
Understanding normal blood sugar levels is crucial for maintaining overall health and preventing serious conditions like diabetes. This article provides a comprehensive guide to normal blood sugar ranges by age, factors affecting these levels, and what to do if your blood sugar readings fall outside the healthy range. Let's dive in!
What are Blood Sugar Levels and Why Do They Matter?
Blood sugar, also known as glucose, is the main source of energy for your body. It comes from the food you eat. Your body regulates blood sugar levels through insulin, a hormone produced by the pancreas. When your blood sugar levels are consistently too high (hyperglycemia) or too low (hypoglycemia), it can lead to serious health problems.
Maintaining healthy blood sugar levels is essential for:
- Energy levels: Stable blood sugar provides consistent energy throughout the day.
- Organ function: High or low blood sugar can damage vital organs.
- Preventing diabetes: Managing blood sugar reduces the risk of developing type 2 diabetes.
Normal Blood Sugar Levels Chart by Age
Keep in mind that these are general guidelines. Individual targets might vary based on personal health conditions and your doctor’s recommendations. These values typically are measured in milligrams per deciliter (mg/dL).
| Age Group | Fasting Blood Sugar (mg/dL) | 2 Hours After Eating (mg/dL) | A1C (%) |
|---|---|---|---|
| Newborns (0-2 years) | 60-100 | Up to 140 | N/A (Not typically measured) |
| Children (2-12 years) | 70-130 | Up to 140 | Less than 7.5% |
| Teens (13-19 years) | 70-130 | Up to 140 | Less than 7.5% |
| Adults (20+ years) without Diabetes | 70-99 | Up to 140 | Less than 5.7% |
| Adults (20+ years) with Diabetes | 80-130 | Less than 180 | Less than 7.0% |
| Older Adults (65+ years) | 80-140 | Up to 180 | Less than 7.5% to 8.5% (Target can be individualized) |
Note: These ranges can vary slightly based on different sources. Always consult your healthcare provider for personalized advice.
Key Blood Sugar Measurement Metrics Explained
- Fasting Blood Sugar: Measured after an overnight fast (at least 8 hours). It indicates how well the body manages blood sugar without recent food intake.
- 2 Hours After Eating (Postprandial): Reflects how well your body processes sugar from a meal. This measurement is taken approximately 2 hours after the start of a meal.
- A1C: Provides an average of your blood sugar control over the past 2-3 months. It's a crucial metric for managing long-term blood sugar levels. Also known as HbA1c or Glycated Hemoglobin.
Factors Affecting Blood Sugar Levels
Many factors can influence your blood sugar levels. Understanding these can help you manage them effectively:
- Diet: Consuming foods high in carbohydrates and sugar can significantly raise blood sugar.
- Physical Activity: Exercise helps lower blood sugar by increasing insulin sensitivity.
- Stress: Stress hormones can increase blood sugar levels.
- Illness: Infections and illnesses can also lead to elevated blood sugar.
- Medications: Certain medications, like steroids, can affect blood sugar levels.
- Age: Blood sugar levels tend to rise with age due to decreased insulin sensitivity and pancreatic function.
- Dehydration: Dehydration can concentrate blood sugar, leading to higher readings.

Hyperglycemia (High Blood Sugar) Symptoms:
- Frequent urination
- Increased thirst
- Blurred vision
- Fatigue
- Slow-healing sores
- Headaches
Hypoglycemia (Low Blood Sugar) Symptoms:
- Shakiness
- Sweating
- Dizziness
- Confusion
- Hunger
- Irritability
- Rapid heartbeat
If you experience any of these symptoms, check your blood sugar immediately and take appropriate action based on your healthcare provider's recommendations. For instance, if you have high blood sugar, try drinking water and going for a short walk. If you have low blood sugar, consuming a fast-acting carbohydrate like juice or glucose tablets can help.
How to Monitor Blood Sugar Levels
Regular blood sugar monitoring is essential, especially for individuals with diabetes. Here are common methods:
- Blood Glucose Meter: This device measures blood sugar levels using a small blood sample obtained from a finger prick.
- Continuous Glucose Monitor (CGM): A CGM is a device that continuously tracks blood sugar levels throughout the day and night. It involves inserting a small sensor under the skin.
- A1C Test: A blood test performed in a lab or clinic to measure average blood sugar levels over the past 2-3 months.
Discuss with your doctor which monitoring method is best suited for your needs. The frequency of monitoring will depend on your health status, treatment plan, and other factors.

Tips for Maintaining Healthy Blood Sugar Levels
Maintaining healthy blood sugar levels involves a combination of lifestyle modifications and medical management:
- Balanced Diet: Focus on whole grains, lean proteins, healthy fats, and plenty of fruits and vegetables. Limit sugary drinks, processed foods, and refined carbohydrates.
- Regular Exercise: Aim for at least 30 minutes of moderate-intensity exercise most days of the week. Exercise helps improve insulin sensitivity and lower blood sugar.
- Weight Management: Maintaining a healthy weight can improve insulin sensitivity and blood sugar control.
- Stress Management: Practice relaxation techniques like yoga, meditation, or deep breathing exercises to reduce stress levels.
- Adequate Sleep: Aim for 7-8 hours of quality sleep each night. Lack of sleep can affect insulin sensitivity and blood sugar levels.
- Stay Hydrated: Drink plenty of water throughout the day to help regulate blood sugar.
- Medication Adherence: If you have diabetes, take your medications as prescribed by your doctor.
- Regular Monitoring: Monitor your blood sugar levels regularly and keep track of your readings.
- Consult Your Doctor: Work closely with your healthcare provider to develop a personalized diabetes management plan.
When to See a Doctor
It's essential to consult a doctor if:
- You consistently experience high or low blood sugar levels outside the target range.
- You have symptoms of diabetes, such as increased thirst, frequent urination, or unexplained weight loss.
- You have a family history of diabetes.
- You are pregnant or planning to become pregnant.
- You have other medical conditions that may affect your blood sugar levels.
- You're experiencing complications related to diabetes, such as nerve damage, kidney disease, or eye problems.
A healthcare professional can help diagnose any underlying issues and provide appropriate treatment and management strategies.
Conclusion
Understanding and managing normal blood sugar levels is essential for overall health and well-being. By following a healthy lifestyle, monitoring your blood sugar regularly, and working closely with your healthcare provider, you can effectively manage your blood sugar levels and prevent complications. Remember that individual targets may vary, so it's always best to seek personalized advice from a healthcare professional.
