The Ultimate Blood Sugar Levels Chart by Age (And What It Means)
Understanding your blood sugar levels is crucial for maintaining overall health, especially as you age. Maintaining healthy blood sugar is essential for preventing a range of health issues, from fatigue and excessive thirst to more serious conditions like diabetes and heart disease. This comprehensive guide provides an ultimate blood sugar levels chart by age, explains what these numbers mean, and offers practical advice for keeping your blood sugar in a healthy range.
Why Monitor Blood Sugar Levels?
Regular monitoring of your blood sugar levels offers several key benefits:
- Early Detection of Diabetes: Identifying prediabetes or type 2 diabetes in its early stages allows for proactive lifestyle changes or medical interventions.
- Management of Existing Diabetes: For those already diagnosed with diabetes, monitoring helps to track the effectiveness of treatment plans and make necessary adjustments.
- Prevention of Complications: Keeping blood sugar within the target range minimizes the risk of long-term complications such as nerve damage, kidney disease, and vision problems.
- Improved Energy Levels: Stable blood sugar avoids energy crashes and fatigue associated with high or low readings.
- Better Overall Health: Maintaining healthy blood sugar contributes to improved cardiovascular health and cognitive function.

Before diving into the blood sugar levels chart by age, it’s important to understand the different types of readings:
- Fasting Blood Sugar (FBS): Measured after an overnight fast (at least 8 hours of no food or drink, except water). It provides a baseline reading of your blood sugar.
- Postprandial Blood Sugar (PPBS): Measured 1-2 hours after eating a meal. It indicates how your body processes carbohydrates.
- Random Blood Sugar (RBS): Measured at any time of day, regardless of when you last ate. This is usually used for initial screening or when symptoms are present.
- A1C Test (Glycated Hemoglobin): Measures your average blood sugar level over the past 2-3 months. It provides a broader view of blood sugar control.

The following table summarizes target blood sugar levels by age group. These ranges are general guidelines and might need adjustment based on individual health conditions and doctor's recommendations. Consult with your healthcare provider for personalized advice.
| Age Group | Fasting Blood Sugar (mg/dL) | 2-Hour Postprandial Blood Sugar (mg/dL) | A1C (%) |
|---|---|---|---|
| Children (Under 6) | 80-180 | Up to 200 | 7.5-8.5% |
| Children (6-12) | 80-120 | Up to 140 | Less than 8% |
| Teenagers (13-19) | 70-150 | Up to 140 | Less than 7.5% |
| Adults (20-59) - Non-Diabetic | 70-99 | Less than 140 | Less than 5.7% |
| Adults (20-59) - Diabetic | 80-130 | Less than 180 | Less than 7% |
| Older Adults (60+) - Non-Diabetic | 80-110 | Less than 160 | Less than 6.5% |
| Older Adults (60+) - Diabetic | 80-150 | Less than 200 | Less than 8% (May be higher based on individual health needs) |
Important Considerations:
- The provided ranges are general guidelines. Individual targets can vary depending on factors like overall health, other medical conditions, and medication.
- Pregnant women have different target ranges for blood sugar. Always follow the advice of your healthcare provider.
- Older adults may have different targets, focusing on avoiding severe hypoglycemia (low blood sugar) rather than strictly adhering to tight control.
Understanding the Readings: What Do They Mean?
- Normal: Indicates healthy blood sugar metabolism.
- Prediabetes: Blood sugar levels are higher than normal but not high enough to be diagnosed as diabetes. This stage often presents an opportunity to prevent the progression to type 2 diabetes through lifestyle changes.
- Diabetes: Blood sugar levels are consistently high, indicating a problem with insulin production or action. Requires medical management.
- Hypoglycemia (Low Blood Sugar): Blood sugar levels are too low, often below 70 mg/dL. This can cause symptoms like shakiness, sweating, confusion, and, in severe cases, loss of consciousness.
Symptoms of High and Low Blood Sugar
Knowing the symptoms of high and low blood sugar can help you take timely action:
Hyperglycemia (High Blood Sugar):
- Increased thirst
- Frequent urination
- Blurred vision
- Fatigue
- Headaches
Hypoglycemia (Low Blood Sugar):
- Shakiness
- Sweating
- Anxiety
- Dizziness
- Confusion
- Hunger
- Irritability
- Rapid heartbeat
- Seizures (in severe cases)
How to Maintain Healthy Blood Sugar Levels
Adopting healthy habits is the cornerstone of maintaining stable blood sugar. Here are some key strategies:
- Balanced Diet:
- Focus on whole, unprocessed foods like fruits, vegetables, whole grains, and lean proteins.
- Limit sugary drinks, processed snacks, and foods high in refined carbohydrates.
- Choose complex carbohydrates over simple carbohydrates to help slow the rate that blood sugar rises after eating.
- Regular Exercise:
- Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Exercise helps your body use insulin more effectively and lowers blood sugar levels.
- Weight Management:
- Maintaining a healthy weight or losing excess weight can significantly improve blood sugar control.
- Stress Management:
- Chronic stress can increase blood sugar levels. Practice relaxation techniques like meditation, yoga, or deep breathing.
- Adequate Sleep:
- Lack of sleep can disrupt hormone levels and affect blood sugar regulation. Aim for 7-8 hours of quality sleep each night.
- Regular Monitoring:
- If you have diabetes or are at risk, monitor your blood sugar regularly as advised by your doctor. This helps you understand how different foods, activities, and medications affect your levels.
- Medication Adherence:
- If you have diabetes, take your medications as prescribed by your doctor. Do not adjust the dosage without consulting your healthcare provider.
