Blood Sugar Levels Chart by Age: What’s Considered Normal?
Understanding blood sugar levels is crucial for maintaining overall health and well-being, especially as we age. Knowing what's considered normal for your age group can help you identify potential issues early and take proactive steps to manage your health. This article will provide a detailed blood sugar levels chart by age, explain the different types of tests used to measure blood sugar, and offer actionable advice on how to maintain healthy levels.
Why Monitoring Blood Sugar is Important

Blood sugar, also known as glucose, is the primary source of energy for the body. It comes from the food we eat. The hormone insulin, produced by the pancreas, helps glucose from food get into cells to be used for energy. When your body doesn't make enough insulin or doesn't use insulin well, glucose stays in the blood, leading to high blood sugar levels. Consistently high blood sugar levels can lead to serious health problems, including:
- Type 2 Diabetes
- Heart Disease
- Kidney Disease
- Nerve Damage (Neuropathy)
- Eye Damage (Retinopathy)
Conversely, low blood sugar (hypoglycemia) can also be dangerous, causing symptoms like dizziness, confusion, and even loss of consciousness. Therefore, regularly monitoring blood sugar levels and maintaining them within a healthy range is essential.
Blood Sugar Levels Chart by Age
These charts offer general guidelines, and individual targets may vary. Consult with your healthcare provider for personalized recommendations.
For Individuals Without Diabetes
| Age Group | Fasting Blood Sugar (mg/dL) | 2-Hour Postprandial (After Eating) (mg/dL) | HbA1c (%) |
|---|---|---|---|
| Children (Under 6) | 80-200 | Less than 180 | N/A |
| Children (6-12) | 70-150 | Less than 140 | N/A |
| Teenagers (13-19) | 70-130 | Less than 140 | Less than 5.7% |
| Adults (20+) | 70-99 | Less than 140 | Less than 5.7% |
| Elderly (65+) | 80-100 | Less than 140 | Less than 7.0% |
For Individuals With Diabetes
| Age Group | Fasting Blood Sugar (mg/dL) | 2-Hour Postprandial (After Eating) (mg/dL) | HbA1c (%) |
|---|---|---|---|
| Children (Under 6) | 80-200 | Less than 180 | N/A |
| Children (6-12) | 90-180 | Less than 180 | N/A |
| Teenagers (13-19) | 70-150 | Less than 180 | Less than 7.5% |
| Adults (20+) | 80-130 | Less than 180 | Less than 7.0% |
| Elderly (65+) | 80-150 | Less than 180 | Less than 8.0% |
- mg/dL: Milligrams per deciliter, the standard unit for measuring blood sugar levels.
- Fasting Blood Sugar: Blood sugar level measured after at least eight hours of fasting (no food or drink).
- 2-Hour Postprandial: Blood sugar level measured two hours after the start of a meal.
- HbA1c: Glycated hemoglobin, which reflects average blood sugar levels over the past 2-3 months.
Understanding the Different Blood Sugar Tests
Several types of tests are used to measure blood sugar. Each provides different insights into your glucose control.
-
Fasting Plasma Glucose (FPG) Test:
- Measured after an overnight fast.
- A result of 126 mg/dL or higher indicates diabetes.
- Between 100 and 125 mg/dL indicates prediabetes.
-
Oral Glucose Tolerance Test (OGTT):
- Involves fasting for at least eight hours, then drinking a sugary liquid.
- Blood sugar levels are measured periodically for two hours.
- A 2-hour reading of 200 mg/dL or higher indicates diabetes.
- Between 140 and 199 mg/dL indicates prediabetes.
-
Random Plasma Glucose Test:
- Measured at any time, regardless of when you last ate.
- A result of 200 mg/dL or higher, along with symptoms of diabetes (frequent urination, excessive thirst, unexplained weight loss), indicates diabetes.
-
A1c Test:
- Doesn't require fasting.
- Indicates your average blood sugar levels over the past 2-3 months.
- A result of 6.5% or higher indicates diabetes.
- Between 5.7% and 6.4% indicates prediabetes.
-
Self-Monitoring of Blood Glucose (SMBG):
- Using a glucose meter at home to check your blood sugar levels throughout the day.
- Helps manage diabetes by providing immediate feedback on how food, exercise, and medication affect your blood sugar.

Many factors can influence your blood sugar levels, including:
- Diet: High-carbohydrate and sugary foods can cause a rapid spike in blood sugar.
- Physical Activity: Exercise can lower blood sugar levels as your body uses glucose for energy.
- Stress: Stress hormones can raise blood sugar levels.
- Illness: Infections and other illnesses can also increase blood sugar levels.
- Medications: Some medications, such as corticosteroids and certain diuretics, can affect blood sugar.
- Hydration: Dehydration can concentrate glucose in the blood, leading to higher readings.
How to Maintain Healthy Blood Sugar Levels
Maintaining healthy blood sugar levels is achievable through lifestyle modifications and, in some cases, medication. Here are some practical steps you can take:
-
Eat a Balanced Diet:
- Focus on whole grains, lean proteins, healthy fats, and plenty of fruits and vegetables.
- Limit processed foods, sugary drinks, and refined carbohydrates.
- Pay attention to portion sizes.
-
Engage in Regular Physical Activity:
- Aim for at least 150 minutes of moderate-intensity aerobic exercise per week.
- Include strength training exercises at least twice a week.
- Consult your doctor before starting a new exercise program.
-
Manage Stress:
- Practice relaxation techniques such as deep breathing, meditation, or yoga.
- Get enough sleep.
- Engage in hobbies and activities you enjoy.
-
Stay Hydrated:
- Drink plenty of water throughout the day to help regulate blood sugar.
-
Monitor Your Blood Sugar Regularly:
- If you have diabetes, follow your doctor's recommendations for blood sugar testing.
- Keep a record of your readings to identify patterns and adjust your management plan as needed.

Conclusion
Understanding and monitoring your blood sugar levels is a vital part of maintaining your health. By knowing the normal ranges for your age group and taking proactive steps to manage your blood sugar through diet, exercise, stress management, and regular monitoring, you can significantly reduce your risk of developing diabetes and its associated complications. Remember to consult with your healthcare provider for personalized advice and guidance on managing your blood sugar.
