The Ultimate Blood Sugar Levels Chart (By Age, Fasting, and After Meals)
Understanding blood sugar levels is critical for maintaining overall health, especially for individuals with diabetes or those at risk. This article provides a comprehensive blood sugar levels chart, broken down by age group, fasting state, and post-meal measurements, offering a clear guide to what's considered normal and when you might need to seek medical advice.
Why Monitor Blood Sugar Levels?
Monitoring your blood sugar levels helps you understand how your body responds to food, exercise, and medication. Regular monitoring can help you and your healthcare provider identify potential problems early and make informed decisions about your treatment plan. Keeping your blood sugar within a healthy range can help prevent or delay long-term health problems associated with diabetes, such as heart disease, kidney disease, and vision loss.
Blood Sugar Levels Chart: General Guidelines
It's important to note that these are general guidelines and individual targets may vary based on factors such as age, overall health, and the specific type of diabetes you have. Always consult with your healthcare provider to determine the best target range for you.
| Category | Target Range (mg/dL) | Target Range (mmol/L) |
|---|---|---|
| Fasting Blood Sugar (Before Breakfast) | 70-100 mg/dL (Non-Diabetic) / 80-130 mg/dL (Diabetic) | 3.9-5.6 mmol/L (Non-Diabetic) / 4.4-7.2 mmol/L (Diabetic) |
| 2 Hours After Meal (Postprandial) | < 140 mg/dL (Non-Diabetic) / < 180 mg/dL (Diabetic) | < 7.8 mmol/L (Non-Diabetic) / < 10.0 mmol/L (Diabetic) |
| HbA1c (Average over 2-3 months) | < 5.7% (Non-Diabetic) / < 7.0% (Diabetic) | N/A |
Blood Sugar Levels By Age
Blood sugar levels can vary slightly across different age groups. It’s crucial to understand these variations to ensure accurate monitoring and management.
Blood Sugar Levels in Children
Managing blood sugar levels in children can be challenging. Targets often need to be individualized, and consistency in meal timings and insulin dosages is key. Regular communication with a pediatric endocrinologist is crucial.
| Category | Target Range (mg/dL) | Notes |
|---|---|---|
| Fasting (Before Meal) | 80-180 mg/dL (Age 0-5) / 80-150 mg/dL (Age 6-12) / 70-130 mg/dL (Age 13-19) | Ranges are wider to reduce the risk of hypoglycemia. |
| Bedtime | 100-180 mg/dL (All Ages) | Ensuring stable levels overnight. |
Blood Sugar Levels in Adults
Adult blood sugar levels are usually targeted more strictly than in children, aiming for optimal control and minimizing long-term complications. Lifestyle modifications play a significant role in managing adult blood sugar.
| Category | Target Range (mg/dL) | Notes |
|---|---|---|
| Fasting (Before Meal) | 70-130 mg/dL | As per general guidelines, individual needs will vary |
| 2 Hours After Meal | < 180 mg/dL | Key time to monitor postprandial glucose response |
Blood Sugar Levels in Seniors

For older adults, especially those with multiple health conditions, the blood sugar targets may be less strict. Preventing severe hypoglycemia is often the primary goal, so slightly higher blood sugars may be acceptable.
| Category | Target Range (mg/dL) | Notes |
|---|---|---|
| Fasting (Before Meal) | 80-150 mg/dL | Individualized to avoid hypoglycemic episodes |
| 2 Hours After Meal | < 200 mg/dL | Focus is on overall well-being and QOL |
Fasting Blood Sugar Levels
Fasting blood sugar is measured after not eating or drinking anything (except water) for at least eight hours. This measurement provides a baseline understanding of your glucose control and can help diagnose diabetes or prediabetes.
| Fasting Blood Sugar (mg/dL) | Interpretation |
|---|---|
| Less than 100 mg/dL | Normal |
| 100-125 mg/dL | Prediabetes |
| 126 mg/dL or higher | Diabetes (confirmed with a second test on a different day) |
Blood Sugar Levels After Meals (Postprandial)

Postprandial blood sugar levels reflect how your body processes glucose after eating. These measurements are usually taken 1-2 hours after starting a meal. Monitoring these levels can help assess the effectiveness of your diet and medications.

| Postprandial Blood Sugar (2 hours after meal) (mg/dL) | Interpretation |
|---|---|
| Less than 140 mg/dL | Normal |
| 140-199 mg/dL | Prediabetes (Impaired Glucose Tolerance) |
| 200 mg/dL or higher | Diabetes |
Factors Affecting Blood Sugar Levels
Many factors can affect your blood sugar levels, including:
- Diet: The type and amount of carbohydrates you eat significantly impacts blood sugar.
- Physical Activity: Exercise helps lower blood sugar levels by increasing insulin sensitivity and burning glucose for energy.
- Medications: Insulin and other diabetes medications directly influence blood sugar. Certain other medications, such as steroids, can raise blood sugar.
- Stress: Stress hormones can increase blood sugar levels.
- Illness: Illness can lead to unpredictable changes in blood sugar levels.
- Sleep: Poor sleep can affect hormone levels and insulin sensitivity, leading to higher blood sugar.
- Hydration: Dehydration can increase blood sugar concentrations.
How to Manage Your Blood Sugar Levels
Managing your blood sugar levels effectively involves a combination of lifestyle modifications and, in some cases, medication.
- Healthy Diet: Focus on a balanced diet rich in whole grains, lean proteins, and plenty of fruits and vegetables. Limit processed foods, sugary drinks, and refined carbohydrates.
- Regular Exercise: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Medication Adherence: If you take medication for diabetes, take it exactly as prescribed by your doctor.
- Regular Monitoring: Check your blood sugar levels regularly and keep a log to track your progress and identify patterns.
- Stress Management: Practice relaxation techniques such as meditation, yoga, or deep breathing exercises to manage stress.
- Stay Hydrated: Drink plenty of water throughout the day.
- Work with a Healthcare Professional: Regular check-ups and guidance from doctors and dietitians are vital.
When to See a Doctor
Consult your doctor if:
- Your blood sugar levels are consistently outside of your target range.
- You experience frequent episodes of hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar).
- You have symptoms of diabetes, such as increased thirst, frequent urination, unexplained weight loss, or blurred vision.
- You are pregnant or planning to become pregnant and have diabetes.
- You have any concerns about managing your blood sugar.
