Your Blood Sugar Levels Chart by Age: What Is a Normal Range for You?
Maintaining healthy blood sugar levels is crucial for overall well-being, regardless of your age. Understanding what constitutes a normal range at different stages of life can help you proactively manage your health and potentially prevent or mitigate the effects of diabetes. This article provides a comprehensive overview of blood sugar levels by age, offering valuable insights into what to expect and when to seek medical advice.
Why Monitor Blood Sugar Levels?
Before diving into the specifics of blood sugar level charts, it's essential to understand why monitoring is so important. Blood glucose, or blood sugar, is the main sugar found in your blood and comes from the food you eat. Your body uses glucose for energy. Consistently high blood sugar levels can lead to:
- Type 2 Diabetes: A chronic condition that affects how your body metabolizes sugar.
- Heart Disease: High blood sugar can damage blood vessels and increase the risk of cardiovascular problems.
- Nerve Damage (Neuropathy): High glucose levels can injure the nerves throughout your body.
- Kidney Damage (Nephropathy): Damage to the filtering system of your kidneys.
- Eye Damage (Retinopathy): Damage to the blood vessels in the retina of the eye, potentially leading to blindness.
Conversely, low blood sugar (hypoglycemia) can cause symptoms such as shakiness, dizziness, confusion, and, in severe cases, loss of consciousness. Regular monitoring allows you to identify and address potential problems early.
Blood Sugar Levels Chart by Age: General Guidelines
While individual circumstances can influence healthy ranges, here are some general guidelines for normal blood sugar levels by age:
| Age Group | Fasting Blood Sugar (mg/dL) | 2 Hours After Eating (mg/dL) | A1C (%) |
|---|---|---|---|
| Children (Under 6) | 80-200 | Up to 200 | N/A (Ranges can be broader) |
| Children (6-12) | 80-180 | Up to 180 | N/A (Ranges can be broader) |
| Teenagers (13-19) | 70-150 | Up to 140 | N/A (Ranges can be broader) |
| Adults (20+) Non-Diabetic | 70-99 | Less than 140 | Less than 5.7% |
| Adults (20+) Diabetic | 80-130 | Less than 180 | Less than 7.0% (as recommended by doctor) |
| Seniors (65+) Non-Diabetic | 80-100 | Less than 140 | Less than 5.7% |
| Seniors (65+) Diabetic | 90-150 | Less than 180 | Less than 7.5% (as recommended by doctor) |
Note: mg/dL refers to milligrams per deciliter, a common unit of measurement for blood sugar levels. A1C represents your average blood sugar level over the past 2-3 months. The provided values are general guidelines and target ranges may differ per individual, consult with a medical professional.
Blood Sugar Levels in Children and Teenagers
Managing blood sugar in children requires special attention. Target ranges for children under 19 are generally broader than adults because their bodies are still developing, and it can be more difficult to control their diet and activity levels consistently. Factors to consider:

- Type 1 Diabetes: Children are more likely to develop type 1 diabetes, an autoimmune condition where the body doesn't produce insulin. This requires careful monitoring and insulin management.
- Growth Spurts: Fluctuations in hormones during puberty can affect blood sugar levels.
- Activity Levels: Children are often more active than adults, which can lower blood sugar.
- Meal Consistency: Maintaining regular meal times is vital for preventing drastic swings.
Parents of children with diabetes should work closely with a pediatrician or endocrinologist to establish individualized blood sugar targets.
Blood Sugar Levels in Adults
For non-diabetic adults, a normal fasting blood sugar is typically between 70 and 99 mg/dL. Two hours after eating, blood sugar should be less than 140 mg/dL.
For adults with diabetes, the target ranges may be different and tailored to their specific needs. Generally, the target fasting blood sugar is often between 80 and 130 mg/dL, and the blood sugar level two hours after eating should be less than 180 mg/dL.
The A1C test provides an average of blood sugar control over the past 2-3 months. For non-diabetic adults, an A1C of less than 5.7% is considered normal. For individuals with diabetes, the goal is usually an A1C of less than 7.0%, but this can vary depending on the individual and their doctor's recommendations.
Blood Sugar Levels in Seniors (65+)
As we age, our bodies become more sensitive to changes in blood sugar. Several factors can contribute to fluctuations in blood sugar levels in seniors:
- Medications: Many seniors take multiple medications, which can interact and affect blood sugar.
- Reduced Kidney Function: Age-related decline in kidney function can impact how the body processes glucose.
- Dietary Changes: Changes in appetite or eating habits can lead to imbalances.
- Reduced Activity: Lower levels of physical activity can contribute to insulin resistance.
The targets for seniors might be adjusted depending on overall health status and other co-existing medical conditions. More flexible targets may be appropriate to avoid dangerous hypoglycemia.
Factors Influencing Blood Sugar Levels
Several factors, besides age, can affect blood sugar levels:

- Diet: The type and amount of carbohydrates you consume have the most direct impact.
- Physical Activity: Exercise helps lower blood sugar by allowing your body to use glucose more effectively.
- Stress: Stress hormones can raise blood sugar levels.
- Illness: Your body releases hormones to fight illness, which can also elevate blood sugar.
- Medications: Certain medications, such as steroids, can increase blood sugar.
- Dehydration: Can lead to higher blood sugar concentration
How to Maintain Healthy Blood Sugar Levels
Maintaining healthy blood sugar levels requires a proactive approach. Here are some key strategies:
- Eat a Balanced Diet: Focus on whole grains, fruits, vegetables, and lean protein. Limit processed foods, sugary drinks, and refined carbohydrates.
- 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 or are at risk, check your blood sugar regularly as directed by your doctor.
- Stay Hydrated: Drink plenty of water throughout the day.
- Manage Stress: Practice relaxation techniques, such as yoga or meditation.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep each night.
When to Seek Medical Advice
It's important to consult with a healthcare professional if you experience any of the following:
- Consistently High Blood Sugar Levels: If your blood sugar readings are frequently above the target range.
- Frequent Low Blood Sugar Levels: If you experience repeated episodes of hypoglycemia.
- Symptoms of Diabetes: Increased thirst, frequent urination, unexplained weight loss, fatigue, blurred vision.
- Family History of Diabetes: If you have a family history of diabetes, you may be at higher risk.
