Blood Sugar Levels Chart by Age: What Are Normal Readings for You?
Understanding your blood sugar levels is crucial for maintaining good health, regardless of age. Monitoring these levels can help prevent or manage diabetes and other related conditions. This article provides a comprehensive overview of normal blood sugar ranges by age, factors that influence these levels, and practical steps you can take to maintain healthy blood sugar.
Why Monitor Blood Sugar Levels?
Blood sugar levels, or blood glucose levels, indicate the amount of glucose present in your blood. Glucose is your body's primary source of energy, and maintaining stable levels is vital for proper organ function. Regularly monitoring blood glucose can:

- Detect early signs of diabetes or prediabetes.
- Help manage existing diabetes.
- Evaluate the effectiveness of diabetes treatment plans.
- Identify potential risks like hyperglycemia (high blood sugar) or hypoglycemia (low blood sugar).
Normal Blood Sugar Levels Chart by Age
While general guidelines exist, normal blood sugar ranges can vary slightly depending on age and individual health conditions. Here's a detailed look at what's generally considered normal:

| Age Group | Fasting Blood Sugar (mg/dL) | 2 Hours After Eating (mg/dL) | A1C (%) |
|---|---|---|---|
| Children (6-12 years) | 80-120 | Less than 140 | Less than 7.5% (Target varies; consult doctor) |
| Teenagers (13-19 years) | 70-130 | Less than 140 | Less than 7.5% (Target varies; consult doctor) |
| Adults (20-59 years) | 70-99 | Less than 140 | Less than 5.7% (Non-diabetic) |
| Seniors (60+ years) | 80-150 (Target may be higher, consult doctor) | Less than 180 (Target may be higher, consult doctor) | Less than 7.0% (Target varies; consult doctor) |
| Diabetic Adults | 80-130 (Target set by doctor) | Less than 180 (Target set by doctor) | Less than 7.0% (Target set by doctor) |
Note: These values are general guidelines. Consult your doctor for personalized targets, especially if you have diabetes or other health conditions. "mg/dL" stands for milligrams per deciliter, a common unit of measurement for blood sugar.
Understanding the Readings:
- Fasting Blood Sugar: Measured after at least eight hours of fasting (no food or drink other than water).
- 2 Hours After Eating: Measured two hours after the start of a meal. This reading indicates how well your body processes glucose from food.
- A1C: Also known as glycated hemoglobin, A1C provides an average of your blood sugar levels over the past 2-3 months. It's expressed as a percentage.
Factors Affecting Blood Sugar Levels
Several factors can influence your blood sugar, causing it to fluctuate throughout the day. These include:
- Diet: Consuming carbohydrates, especially refined sugars and processed foods, can cause a rapid increase in blood glucose.
- Physical Activity: Exercise helps lower blood sugar by increasing insulin sensitivity and helping your muscles use glucose for energy.
- Stress: Stress hormones like cortisol can raise blood glucose levels.
- Medications: Certain medications, such as steroids and diuretics, can affect blood sugar.
- Illness: Infections and illnesses can impact blood sugar levels.
- Sleep: Insufficient or poor-quality sleep can disrupt hormone levels and affect glucose metabolism.
- Age: As we age, insulin sensitivity can decrease, potentially leading to higher blood sugar.
- Hydration: Dehydration can concentrate blood sugar, leading to higher readings.

How to Maintain Healthy Blood Sugar Levels
Adopting healthy lifestyle habits can help keep your blood sugar levels within the normal range.
- Eat a Balanced Diet: Focus on whole, unprocessed foods, including fruits, vegetables, lean proteins, and whole grains. Limit sugary drinks, processed snacks, and refined carbohydrates. Practice portion control to prevent overeating.
- Exercise Regularly: Aim for at least 30 minutes of moderate-intensity exercise most days of the week. This could include brisk walking, cycling, swimming, or dancing. Resistance training can also improve insulin sensitivity.
- Stay Hydrated: Drink plenty of water throughout the day. Dehydration can affect blood sugar levels.
- Manage Stress: Practice relaxation techniques such as meditation, yoga, or deep breathing exercises to reduce stress.
- Get Enough Sleep: Aim for 7-9 hours of quality sleep each night.
- Monitor Blood Sugar Regularly: If you have diabetes or are at risk, monitor your blood sugar as directed by your doctor. Keep a record of your readings and share them with your healthcare provider.
- Follow Your Doctor's Recommendations: If you have diabetes, work closely with your doctor to develop a personalized treatment plan. This may include medication, insulin therapy, and lifestyle modifications.
When to See a Doctor
Consult your doctor if you experience any of the following:
- Consistently high or low blood sugar readings.
- Symptoms of hyperglycemia or hypoglycemia.
- Sudden or unexplained changes in your blood sugar levels.
- Difficulty managing your diabetes.
- If you have concerns about your blood sugar based on your age and health status.
The Importance of Regular Check-ups
Regular check-ups with your doctor are vital for monitoring your overall health, including blood sugar levels. Your doctor can perform routine blood sugar tests, assess your risk for diabetes, and provide personalized advice on how to maintain healthy blood glucose levels.
Conclusion
Understanding your blood sugar levels by age is crucial for maintaining overall health and preventing or managing diabetes. By following the guidelines provided in this article, adopting healthy lifestyle habits, and working closely with your doctor, you can effectively manage your blood sugar and reduce your risk of developing complications. Remember that personalized targets may vary, so always consult your healthcare provider for guidance tailored to your specific needs.
