Are Your Blood Sugar Levels Normal? The Ultimate Chart by Age
Understanding your blood sugar levels is crucial for maintaining overall health and preventing serious conditions like diabetes. Fluctuations in blood glucose levels can indicate potential problems, and knowing what's considered normal for your age group is the first step in taking proactive care of your well-being. This article provides a comprehensive guide to normal blood sugar ranges by age, as well as factors that can influence these levels and what steps to take if your results fall outside the optimal range.
Why is Monitoring Blood Sugar Important?
Blood sugar, or blood glucose, is the primary source of energy for your body. It comes from the food you eat, and your pancreas produces insulin to help your body use glucose for energy or store it for later use. When this process isn't working correctly—either because the pancreas doesn't produce enough insulin or because the body can't use insulin effectively—blood sugar levels can become too high (hyperglycemia) or too low (hypoglycemia).

Monitoring your blood sugar helps:
- Detect prediabetes and diabetes early.
- Manage existing diabetes effectively.
- Identify the impact of diet, exercise, and medications on blood sugar levels.
- Prevent long-term complications associated with uncontrolled blood sugar, such as heart disease, kidney disease, nerve damage, and vision problems.
Blood Sugar Levels Chart by Age
The following chart provides a general guideline for normal blood sugar levels at different times of the day for people without diabetes, categorized by age group. Note that these ranges can vary slightly depending on the source and individual circumstances. Always consult with your healthcare provider for personalized recommendations.
| Age Group | Fasting Blood Sugar (mg/dL) | 2 Hours After Eating (mg/dL) | A1C |
|---|---|---|---|
| Children (Under 6) | 80-180 | Up to 200 | 5.5% - 8.0% |
| Children (6-12) | 80-120 | Up to 140 | Less than 7.5% |
| Teens (13-19) | 70-150 | Up to 140 | Less than 7.5% |
| Adults (20+) Without Diabetes | 70-99 | Less than 140 | Less than 5.7% |
| Adults (20+) With Diabetes | 80-130 | Less than 180 | Less than 7.0% (as recommended by your doctor) |
| Seniors (65+) Without Diabetes | 80-100 | Less than 140 | Less than 5.7% |
| Seniors (65+) With Diabetes | 90-150 | Less than 180 | Less than 7.5% (as recommended by your doctor) |
- Fasting Blood Sugar: Measured after at least eight hours of fasting (not eating or drinking anything besides water).
- 2 Hours After Eating: Measured two hours after the start of a meal.
- A1C: The A1C test measures your average blood sugar level over the past 2-3 months. It is a percentage; higher percentages indicate higher average blood sugar levels.
Understanding the Numbers
- Normal: Indicates healthy blood sugar control.
- Prediabetes: Fasting blood sugar between 100-125 mg/dL or an A1C between 5.7-6.4% suggests prediabetes.
- Diabetes: Fasting blood sugar of 126 mg/dL or higher, or an A1C of 6.5% or higher on two separate tests indicates diabetes. Post-meal levels consistently over 200mg/dL can also be indicative.
Factors That Affect Blood Sugar Levels
Many factors can influence your blood sugar levels, including:
- Diet: Carbohydrates have the most significant impact on blood sugar. The type and amount of carbohydrates you consume play a crucial role. High-fiber foods tend to have a more gradual effect.
- Physical Activity: Exercise helps lower blood sugar as your body uses glucose for energy. Regular physical activity also improves insulin sensitivity.
- Stress: Stress hormones can raise blood sugar levels. Managing stress through relaxation techniques, mindfulness, or therapy can help maintain stable blood glucose.
- Illness: When you're sick, your body may release hormones to fight the illness, which can increase blood sugar.
- Medications: Certain medications, such as steroids, diuretics, and some antidepressants, can affect blood sugar levels.
- Age: As you age, your body may become less efficient at regulating blood sugar. This can lead to increased risk of insulin resistance and type 2 diabetes.
- Genetics: Family history of diabetes significantly increases your risk.
Symptoms of High and Low Blood Sugar
Recognizing the symptoms of both high and low blood sugar is crucial for prompt management.
Symptoms of High Blood Sugar (Hyperglycemia):

- Blurred vision
If you experience any of these symptoms, check your blood sugar if possible. If you have diabetes, follow your healthcare provider’s recommendations for managing high or low blood sugar. If you don't have diabetes but frequently experience these symptoms, consult a doctor for evaluation.
How to Maintain Healthy Blood Sugar Levels
Here are some practical strategies to help maintain healthy blood sugar levels:

- Spread carbohydrate intake evenly throughout the day.
- Engage in Regular Physical Activity:
- Aim for at least 150 minutes of moderate-intensity exercise per week.
- Incorporate both aerobic exercises (like walking, swimming, or cycling) and strength training.
- Monitor your blood sugar before, during, and after exercise to understand how it affects your levels.
- Manage Stress:
- Practice relaxation techniques such as deep breathing, meditation, or yoga.
- Get adequate sleep.
- Engage in hobbies and activities you enjoy.

When to See a Doctor
It's essential to see a doctor if:
- You consistently have blood sugar levels outside the normal range.
- You experience frequent symptoms of hyperglycemia or hypoglycemia.
- You have risk factors for diabetes, such as family history, obesity, or sedentary lifestyle.
- You are pregnant or planning to become pregnant and have concerns about blood sugar control.
- You have been diagnosed with prediabetes and want to take steps to prevent progression to type 2 diabetes.
