Blood Sugar Levels Chart by Age: Your Guide to Normal Ranges
Understanding your blood sugar levels is crucial for maintaining good health, regardless of your age. But what's considered "normal" can vary across different age groups. This comprehensive guide will walk you through blood sugar level charts by age, explaining what the numbers mean and how to keep your levels in check. Let's dive in!
Why Blood Sugar Levels Matter
Blood sugar, or glucose, is the primary source of energy for your body's cells. Insulin, a hormone produced by the pancreas, helps glucose from the food you eat enter your cells to be used for energy. When your blood sugar levels are consistently too high (hyperglycemia) or too low (hypoglycemia), it can lead to serious health problems, including diabetes, heart disease, and kidney damage. Regular monitoring and understanding what’s normal for your age can help you take proactive steps toward a healthier life.
Understanding the Different Types of Blood Sugar Tests
Before we delve into the age-specific ranges, it's important to understand the different types of blood sugar tests:
- Fasting Blood Sugar (FBS) Test: This test measures your blood sugar levels after an overnight fast (typically 8 hours).
- Postprandial Blood Sugar (PPBS) Test: This test measures your blood sugar levels two hours after you start eating a meal.
- Random Blood Sugar (RBS) Test: This test measures your blood sugar levels at any time of day, without regard to meals.
- A1C Test: This test measures your average blood sugar levels over the past 2-3 months. It doesn’t require fasting.
Each test provides a different snapshot of your blood sugar control, and your doctor will likely use a combination of these to get a comprehensive view.

While individual needs can vary, these charts provide general guidelines for normal blood sugar levels by age group for non-diabetics. Remember, these are just general guidelines and consultation with a healthcare professional is recommended for personalized assessment.
Children (Under 18)
| Test | Normal Range |
|---|---|
| Fasting Blood Sugar | 70-150 mg/dL |
| Postprandial Blood Sugar (2 hours after eating) | Less than 180 mg/dL |
| A1C | Less than 7.5% (individual target may vary depending on the child and the healthcare team) |
Important Considerations for Children: Blood sugar management in children can be particularly challenging due to growth spurts, varying activity levels, and dietary habits. Close monitoring and communication with a pediatrician or endocrinologist are essential. Furthermore, A1C targets can be individualized to prevent episodes of hypoglycemia and to minimize burden of care.
Adults (18-59)
| Test | Normal Range |
|---|---|
| Fasting Blood Sugar | 70-99 mg/dL |
| Postprandial Blood Sugar (2 hours after eating) | Less than 140 mg/dL |
| A1C | Less than 5.7% |
Important Considerations for Adults: Maintaining healthy blood sugar levels in adulthood involves lifestyle choices like diet and exercise. Regular physical activity and a balanced diet rich in fruits, vegetables, and whole grains are crucial for preventing insulin resistance and type 2 diabetes.
Seniors (60+)
| Test | Normal Range |
|---|---|
| Fasting Blood Sugar | 70-100 mg/dL |
| Postprandial Blood Sugar (2 hours after eating) | Less than 160 mg/dL |
| A1C | Less than 7.0% (individual target may vary depending on other health conditions) |
Important Considerations for Seniors: As you age, your body's ability to regulate blood sugar may decline. Furthermore, certain medical conditions and medications can affect your levels. Monitoring blood sugar and having more liberal targets may be recommended if someone is frail or has frequent episodes of hypoglycemia. More flexible A1C targets can be helpful in minimizing the risk of falls that can occur with hypoglycemia.

What To Do If Your Blood Sugar Levels Are High
If your blood sugar levels consistently fall outside of the normal ranges, it's essential to consult with a healthcare professional. They can help you determine the underlying cause and develop a personalized treatment plan. Here are some general recommendations:
- Dietary Changes: Focus on a diet low in processed foods, sugary drinks, and refined carbohydrates. Emphasize whole grains, lean proteins, and plenty of fruits and vegetables.
- Regular Exercise: Aim for at least 150 minutes of moderate-intensity exercise per week. Even short walks can make a significant difference.
- Medication: If lifestyle changes aren't enough, your doctor may prescribe medications to help lower your blood sugar levels. Common medications include metformin, sulfonylureas, and insulin.
- Regular Monitoring: Regularly check your blood sugar levels as directed by your healthcare provider. Keep a record of your readings and share them with your doctor.
What To Do If Your Blood Sugar Levels Are Low
Hypoglycemia, or low blood sugar, can be dangerous if left untreated. Here’s what to do if you suspect your blood sugar is low:
- Check Your Blood Sugar: If possible, use a blood glucose meter to confirm that your blood sugar is indeed low.
- Eat or Drink Something Sweet: If your blood sugar is below 70 mg/dL, consume 15-20 grams of fast-acting carbohydrates, such as glucose tablets, fruit juice, or regular (non-diet) soda.
- Wait 15 Minutes: Recheck your blood sugar after 15 minutes. If it's still low, repeat the process.
- Follow Up with a Meal: Once your blood sugar is back to normal, eat a meal or snack to prevent it from dropping again.
Important: If you experience frequent episodes of hypoglycemia, talk to your doctor to identify the underlying cause and adjust your treatment plan.
