- Detect diabetes and prediabetes early.
- Manage existing diabetes effectively.
- Understand how food, exercise, and medications affect blood glucose levels.
- Reduce the risk of long-term complications associated with high or low blood sugar.
Knowing what's normal for your age group is a critical first step in proactive health management. So, let's dive into the specific blood sugar ranges.
Understanding the Different Types of Blood Sugar Tests
Before we jump into the charts, it’s essential to understand the common types of blood sugar tests:
- Fasting Blood Sugar (FBS): Measured after at least eight hours of fasting (no food or drink, except water). This is often the first test used to screen for diabetes.
- Postprandial Blood Sugar (PPBS): Measured two hours after starting a meal. It reflects how well your body processes glucose after eating.
- HbA1c Test (Glycated Hemoglobin): Provides an average of your blood sugar levels over the past 2-3 months. It's a key indicator for long-term diabetes management.
- Random Blood Sugar: Measured at any time of day, regardless of when you last ate. This test is often used when diagnosing diabetes in individuals with severe symptoms.
Now that we know the tests, let’s get to the heart of the article - the blood sugar levels chart by age.
Blood Sugar Levels Chart by Age
This section breaks down the ideal blood sugar levels for different age groups, including children, adults, and seniors. Remember, these ranges are general guidelines, and your healthcare provider may recommend slightly different targets based on your individual health profile.
Children (Under 18)
| Test | Normal Range | Target for Children with Diabetes |
|---|---|---|
| Fasting Blood Sugar | 70-100 mg/dL | 70-130 mg/dL |
| Before Meals | 70-100 mg/dL | 70-130 mg/dL |
| 1-2 hours After Meals | Less than 140 mg/dL | Less than 180 mg/dL |
| HbA1c | Less than 5.7% | Less than 7.5% (may vary based on age and individual needs) |
Important Considerations for Children: Maintaining stable blood sugar levels in children is essential for their growth and development. Fluctuations can be particularly harmful, requiring careful management.
Adults (18-59)
| Test | Normal Range | Target for Adults with Diabetes |
|---|---|---|
| Fasting Blood Sugar | 70-99 mg/dL | 80-130 mg/dL |
| Postprandial (2 hours after eating) | Less than 140 mg/dL | Less than 180 mg/dL |
| HbA1c | Less than 5.7% | Less than 7% |
Adults and Prediabetes: If your fasting blood sugar consistently falls between 100-125 mg/dL, you may have prediabetes. Early intervention is crucial to prevent the progression to type 2 diabetes. Lifestyle changes such as diet and exercise can have a significant impact.

Seniors (60+)
| Test | Normal Range | Target for Seniors with Diabetes |
|---|---|---|
| Fasting Blood Sugar | 70-100 mg/dL | 80-130 mg/dL (may be higher based on overall health) |
| Postprandial (2 hours after eating) | Less than 140 mg/dL | Less than 180 mg/dL (may be more lenient based on overall health) |
| HbA1c | Less than 5.7% | Less than 7.5% (individualized target is key) |
Important Note for Seniors: As we age, the target ranges for blood sugar levels may be less strict, particularly if there are other health concerns. The focus is often on avoiding severe hypoglycemia (low blood sugar). A personalized approach in consultation with a healthcare provider is crucial.
What to Do If Your Blood Sugar Levels Are High or Low
Understanding what to do when your blood sugar levels are outside the normal range is vital. Here's a breakdown of potential actions:
High Blood Sugar (Hyperglycemia)
- Check Again: Confirm the reading with a second test.
- Stay Hydrated: Drink plenty of water to help flush out excess sugar.
- Exercise: If appropriate and safe, light exercise can help lower blood sugar. (Consult your doctor first, especially if you have ketones present).
- Medication: If you have diabetes, take your prescribed medication as directed.
- Contact Your Doctor: If blood sugar levels remain high or you experience symptoms like excessive thirst, frequent urination, blurred vision, or fatigue, seek medical attention.
Low Blood Sugar (Hypoglycemia)
- Follow the 15-15 Rule: Eat 15 grams of fast-acting carbohydrates (e.g., glucose tablets, juice, hard candy) and check your blood sugar after 15 minutes. Repeat if still low.
- Have a Meal or Snack: Once your blood sugar is back in the normal range, eat a balanced meal or snack to prevent it from dropping again.
- Carry a Medical ID: Wear a medical ID bracelet or necklace to alert others in case of emergency.
- Inform Family and Friends: Teach loved ones how to recognize and treat hypoglycemia.
Tips for Maintaining Healthy Blood Sugar Levels
Whether you have diabetes or simply want to optimize your health, these strategies can help:
- Eat a Balanced Diet: Focus on whole, unprocessed foods, including plenty of fruits, vegetables, lean protein, and whole grains.
- Control Portion Sizes: Be mindful of how much you're eating at each meal.
- Exercise Regularly: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Monitor Your Blood Sugar: If you have diabetes, check your blood sugar regularly as directed by your doctor. Even without diabetes, occasional checks can provide valuable insights.
- Manage Stress: High stress levels can impact blood sugar. Practice relaxation techniques like meditation or yoga.
- Get Enough Sleep: Lack of sleep can affect insulin sensitivity. Aim for 7-9 hours of quality sleep per night.
- Limit Alcohol: Alcohol can lower blood sugar, especially when consumed on an empty stomach. If you drink, do so in moderation and with food.
- Stay Hydrated: Dehydration can affect blood sugar concentration.
