The Ultimate Blood Sugar Levels Chart by Age (and What It Means)
Maintaining healthy blood sugar levels is crucial for overall well-being. Whether you're managing diabetes, are pre-diabetic, or simply aiming for a healthier lifestyle, understanding what constitutes normal blood glucose levels at different ages is key. This comprehensive guide provides the ultimate blood sugar chart by age, explains what these numbers mean, and offers insights into maintaining optimal health.
Why Blood Sugar Levels Matter
Blood sugar, or glucose, is your body's primary source of energy. It comes from the food you eat. Insulin, a hormone produced by the pancreas, helps glucose from food get into your cells to be used for energy.
When you have diabetes or pre-diabetes, your body either doesn't make enough insulin or can't effectively use the insulin it does make. This leads to elevated blood sugar levels, which over time, can cause serious health problems, including:
- Heart disease
- Kidney disease
- Nerve damage (neuropathy)
- Vision loss
Therefore, regularly monitoring and managing your blood sugar is vital.

Understanding Blood Sugar Readings: A Quick Overview
Before diving into the blood sugar chart by age, it's important to understand the different types of blood sugar readings:
- Fasting Blood Sugar (FBS): Measured after an overnight fast (at least 8 hours). This gives a baseline glucose level.
- Postprandial Blood Sugar (PPBS): Measured 1-2 hours after a meal. This indicates how your body processes glucose after eating.
- A1C (Glycated Hemoglobin): Provides an average of your blood sugar control over the past 2-3 months. It's not a daily measurement but gives a long-term perspective.
- Random Blood Sugar: Measured at any time of the day, regardless of when you last ate.
The Ultimate Blood Sugar Levels Chart by Age
The following chart outlines the general target blood sugar levels for different age groups. Keep in mind these are general guidelines and individual targets may vary based on specific health conditions or advice from your healthcare provider. Always consult your doctor for personalized guidance.
Age Group | Fasting Blood Sugar (mg/dL) | Postprandial Blood Sugar (1-2 hours after eating) (mg/dL) | A1C (%) |
---|---|---|---|
Children (6-12 years) – Non-Diabetic | 70-130 | Up to 140 | Less than 5.7% |
Teenagers (13-19 years) – Non-Diabetic | 70-130 | Up to 140 | Less than 5.7% |
Adults (20+ years) – Non-Diabetic | 70-99 | Up to 140 | Less than 5.7% |
Adults (20+ years) - Diabetic | 80-130 | Less than 180 | Less than 7.0% (as per ADA guidelines, individualized goals may differ) |
Seniors (65+ years) – Generally | 80-180 (depends on health status and medications) | Up to 180 (depends on health status and medications) | Less than 7.5% (individualized goals may differ) |
Note: mg/dL = milligrams per deciliter

Important Considerations:
- Individuals with diabetes will likely have different target ranges set by their healthcare provider. The American Diabetes Association (ADA) guidelines are commonly used, but personal goals may be more stringent or more relaxed based on various health factors.
- For seniors, target ranges may be less strict to avoid hypoglycemia (low blood sugar), especially if they have other health conditions.
- Children with diabetes will have individual target ranges set by their pediatrician or endocrinologist.
Understanding Blood Sugar Levels: What the Numbers Mean
Here’s a breakdown of what different blood sugar ranges indicate:
- Normal: Generally, a fasting blood sugar level between 70-99 mg/dL is considered normal. A PPBS below 140 mg/dL is also considered healthy.
- Prediabetes: A fasting blood sugar between 100-125 mg/dL indicates prediabetes. This means you are at a higher risk of developing type 2 diabetes. Lifestyle changes can often reverse prediabetes.
- Diabetes: A fasting blood sugar of 126 mg/dL or higher on two separate tests, or an A1C of 6.5% or higher, indicates diabetes.
How to Maintain Healthy Blood Sugar Levels
Maintaining stable blood sugar levels is essential for overall health and preventing diabetes-related complications. Here are some key strategies:
-
Balanced Diet:
- Focus on whole, unprocessed foods.
- Choose complex carbohydrates over simple sugars (e.g., whole grains, vegetables, and fruits over white bread, sugary drinks, and processed snacks).
- Include lean protein sources (e.g., chicken, fish, beans).
- Eat healthy fats (e.g., avocados, nuts, olive oil).
- Control portion sizes to manage carbohydrate intake.
-
Regular Exercise:
- Engage in at least 150 minutes of moderate-intensity aerobic exercise per week.
- Include strength training exercises at least twice a week.
- Physical activity helps improve insulin sensitivity and lowers blood sugar.
-
Weight Management:
- Maintaining a healthy weight can improve insulin sensitivity and blood sugar control.
- Even losing a small amount of weight (5-10% of your body weight) can have significant benefits.
-
Regular Blood Sugar Monitoring:

- If you have diabetes, regularly monitor your blood sugar levels as recommended by your healthcare provider.
- This helps you understand how food, exercise, and medication affect your blood sugar.
-
Medication Management:
- If you have diabetes, take your medications as prescribed by your doctor.
- Do not adjust your medication dosage without consulting your healthcare provider.
-
Stress Management:
- Stress can affect blood sugar levels.
- Practice relaxation techniques such as meditation, yoga, or deep breathing exercises.
-
Adequate Sleep:
- Aim for 7-9 hours of quality sleep per night.
- Lack of sleep can affect insulin sensitivity and blood sugar control.
Factors That Can Affect Blood Sugar Levels
Several factors can influence your blood sugar levels, including:
- Food choices: High-carbohydrate and sugary foods can cause a rapid increase in blood sugar.
- Physical activity: Exercise lowers blood sugar, while inactivity can increase it.
- Stress: Stress hormones can raise blood sugar.
- Illness: Infections and illnesses can affect blood sugar.
- Medications: Certain medications, such as steroids, can increase blood sugar.
- Dehydration: Dehydration can concentrate blood sugar, leading to higher readings.
- Menstrual cycle: Hormonal changes during menstruation can affect blood sugar in women.
When to See a Doctor
It’s crucial to consult a doctor if:
- You experience frequent symptoms of high blood sugar (e.g., increased thirst, frequent urination, blurred vision, fatigue).
- You have a family history of diabetes.
- You are overweight or obese.
- You have prediabetes.
- You have risk factors for type 2 diabetes (e.g., high blood pressure, high cholesterol).
- You are pregnant or planning to become pregnant.
Your healthcare provider can perform blood sugar tests, assess your risk factors, and recommend appropriate treatment or management strategies.
