Blood Sugar Levels Chart by Age: What Are Normal Ranges for You?
Understanding your blood sugar levels is crucial for maintaining good health, regardless of your age. Blood sugar, or glucose, is the main sugar found in your blood and comes from the food you eat. It's your body's primary source of energy. Maintaining healthy blood sugar levels is essential for preventing various health complications, including diabetes. But what are considered normal ranges, and how do they vary by age? Let's dive in.
Why Blood Sugar Levels Matter
Maintaining balanced blood sugar levels helps your body function optimally. When your blood sugar levels are too high (hyperglycemia) or too low (hypoglycemia), it can lead to a range of symptoms and health problems.
- Hyperglycemia: High blood sugar levels can cause increased thirst, frequent urination, blurred vision, and fatigue. Over time, chronic hyperglycemia can damage your nerves, blood vessels, and organs, leading to complications like heart disease, kidney disease, and nerve damage (neuropathy).
- Hypoglycemia: Low blood sugar levels can cause shakiness, sweating, confusion, dizziness, and even loss of consciousness. Hypoglycemia can be particularly dangerous for individuals with diabetes who are taking insulin or other medications that lower blood sugar.
Regular monitoring of your blood sugar levels can help you identify potential issues early and take steps to manage them effectively.
Normal Blood Sugar Ranges by Age
While individual needs may vary, the following ranges are generally considered normal for different age groups. These values are often based on guidelines from organizations like the American Diabetes Association (ADA).
Children (Under 18)
For children without diabetes, the following ranges are typical:
- Fasting Blood Sugar: 70-100 mg/dL
- Before Meals: 70-130 mg/dL
- 1-2 Hours After Meals: Less than 140 mg/dL
Keep in mind that children with diabetes may have slightly different target ranges as determined by their healthcare provider. Consistent monitoring is key to effective diabetes management.
Adults (18-59)
For non-pregnant adults without diabetes, the generally accepted normal blood sugar ranges are:
- Fasting Blood Sugar: 70-99 mg/dL
- Before Meals: 70-130 mg/dL
- 1-2 Hours After Meals: Less than 140 mg/dL
These ranges may be slightly different for individuals managing diabetes. It is important to collaborate with your doctor to establish personalized targets.
Seniors (60+)

As we age, the body's ability to regulate blood sugar can change. Older adults may also have other health conditions or be taking medications that affect blood sugar levels.
- Fasting Blood Sugar: 80-120 mg/dL
- Before Meals: 80-140 mg/dL
- 1-2 Hours After Meals: Less than 160 mg/dL
The slightly higher ranges are often deemed acceptable to minimize the risk of hypoglycemia, which can be particularly dangerous for older adults. Individual target ranges should still be determined by a healthcare professional.

Here's a summarized view of the normal blood sugar ranges across different age groups.
| Age Group | Fasting Blood Sugar (mg/dL) | Before Meals (mg/dL) | 1-2 Hours After Meals (mg/dL) |
|---|---|---|---|
| Children (Under 18) | 70-100 | 70-130 | Less than 140 |
| Adults (18-59) | 70-99 | 70-130 | Less than 140 |
| Seniors (60+) | 80-120 | 80-140 | Less than 160 |
Important Note: These are general guidelines and individual needs may vary. Consult with your healthcare provider to determine your ideal blood sugar ranges.
Factors Affecting Blood Sugar Levels
Several factors can influence your blood sugar levels, including:
- Diet: The type and amount of carbohydrates you consume have a significant impact. High-sugar and processed foods can cause rapid spikes in blood sugar.
- Physical Activity: Exercise helps lower blood sugar by increasing insulin sensitivity and helping your muscles use glucose for energy.
- Medications: Certain medications, such as steroids and some antidepressants, can affect blood sugar levels.
- Stress: Stress hormones can raise blood sugar levels.
- Illness: When you're sick, your body may produce more glucose, leading to higher blood sugar levels.
- Dehydration: Dehydration can concentrate glucose in your blood, leading to higher readings.
Understanding these factors can help you better manage your blood sugar levels through lifestyle adjustments and medical interventions, if needed.
How to Monitor Your Blood Sugar Levels
Regular blood sugar monitoring is vital, especially for individuals with diabetes or those at risk of developing the condition. Here are common methods for monitoring:

- Blood Glucose Meter: A blood glucose meter requires a small blood sample, usually obtained by pricking your finger. The meter provides a reading of your blood sugar level at that moment.
- Continuous Glucose Monitor (CGM): A CGM is a device that continuously tracks your blood sugar levels throughout the day and night. It uses a small sensor inserted under your skin to measure glucose levels in interstitial fluid.
- A1C Test: The A1C test measures your average blood sugar level over the past 2-3 months. It provides a broader picture of your blood sugar control.
Your healthcare provider can help you determine the most appropriate monitoring method and frequency based on your individual needs.
Lifestyle Changes for Better Blood Sugar Control
Adopting a healthy lifestyle can significantly improve blood sugar control and reduce the risk of diabetes.
- Eat a Balanced Diet: Focus on whole foods, including fruits, vegetables, whole grains, and lean protein. Limit sugary drinks, processed foods, and excessive amounts of carbohydrates.
- Engage in Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity exercise per week.
- Maintain a Healthy Weight: Losing even a small amount of weight can improve insulin sensitivity and lower blood sugar levels.
- Manage Stress: Practice relaxation techniques like yoga, meditation, or deep breathing exercises to reduce stress levels.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep per night.
These lifestyle changes can help you maintain healthy blood sugar levels and reduce your risk of diabetes and related complications.

When to See a Doctor
It's important to consult with a healthcare professional if you experience any of the following:
- Frequent Hyperglycemia or Hypoglycemia: Consistent high or low blood sugar levels warrant medical attention.
- Symptoms of Diabetes: Increased thirst, frequent urination, unexplained weight loss, and blurred vision can be signs of diabetes.
- Family History of Diabetes: If you have a family history of diabetes, you may be at increased risk and should discuss screening with your doctor.
- Difficulty Managing Blood Sugar: If you are having trouble controlling your blood sugar levels despite lifestyle changes and/or medication, seek medical advice.
Early detection and management of blood sugar imbalances are crucial for preventing long-term health complications. Regularly checking your blood sugar, and understanding the normal ranges by age, are crucial steps toward managing your health. Always consult your doctor for personalized advice.
