The Definitive Blood Sugar Levels Chart by Age: What's Healthy for You?
Understanding blood sugar levels is essential for maintaining good health, regardless of age. These levels provide insights into how well your body is processing glucose, a primary source of energy. Maintaining optimal blood sugar can help prevent a range of health issues, including diabetes. In this comprehensive guide, we’ll break down healthy blood sugar ranges by age, discuss the factors that affect these levels, and offer practical tips to help you stay within a healthy range.
Why Blood Sugar Levels Matter
Blood glucose, often referred to as blood sugar, is the concentration of glucose present in the blood. This glucose comes from the food we eat and is our body's main source of energy. The hormone insulin, produced by the pancreas, helps glucose move from the bloodstream into cells where it can be used for energy.
When blood sugar levels are consistently too high (hyperglycemia) or too low (hypoglycemia), it can lead to various health problems. Hyperglycemia over time can result in damage to organs, nerves, and blood vessels, leading to complications like heart disease, kidney disease, and vision problems. Hypoglycemia, while often acute, can cause dizziness, confusion, and even loss of consciousness.
Regularly monitoring blood sugar helps you understand how diet, exercise, and other factors affect your glucose levels. This information is crucial for managing diabetes or prediabetes effectively and maintaining overall health.
Understanding Blood Sugar Readings
Before diving into age-specific ranges, it’s important to understand the different types of blood sugar tests and their measurements. Blood sugar levels are typically measured in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). The main types of tests include:

- Fasting Blood Sugar (FBS): Measured after an overnight fast (usually 8 hours).
- Postprandial Blood Sugar (PPBS): Measured 1-2 hours after eating a meal.
- Random Blood Sugar (RBS): Measured at any time of the day, regardless of when you last ate.
- A1C Test: Measures average blood sugar levels over the past 2-3 months.
Blood Sugar Levels Chart by Age: Healthy Ranges
It's essential to understand that these are general guidelines and individual circumstances may vary. Consulting with a healthcare professional is crucial for personalized advice.
Age Group | Fasting Blood Sugar (mg/dL) | Postprandial Blood Sugar (1-2 hours after eating) (mg/dL) | A1C (%) |
---|---|---|---|
Children (6-12 years) | 80-120 | Up to 140 | Less than 7.5 |
Teenagers (13-19 years) | 70-150 | Up to 140 | Less than 7.5 |
Adults (20-59 years) (Non-Diabetic) | 70-100 | Less than 140 | Less than 5.7 |
Adults (60+ years) (Non-Diabetic) | 80-110 | Less than 140 | Less than 7.0 |
Adults (with Diabetes) | 80-130 | Less than 180 | Less than 7.0 (as advised by doctor) |
Blood Sugar Levels in Children (6-12 Years) and Teenagers (13-19 Years)
Maintaining stable blood sugar is particularly important during childhood and adolescence due to growth and development. In children, the target ranges are typically:
- Fasting Blood Sugar: 80-120 mg/dL
- Postprandial Blood Sugar: Up to 140 mg/dL
- A1C: Less than 7.5% (Target may vary depending on individual health conditions).
For teenagers, similar guidelines apply, but lifestyle factors can significantly impact blood sugar levels. Puberty, stress, dietary choices, and physical activity all play a role. Monitoring becomes crucial during these formative years.
Blood Sugar Levels in Adults (20-59 Years)
For adults, maintaining healthy blood sugar is crucial for preventing long-term health complications. Here are the general ranges for non-diabetic adults:
- Fasting Blood Sugar: 70-100 mg/dL
- Postprandial Blood Sugar: Less than 140 mg/dL
- A1C: Less than 5.7%
If an individual is diagnosed with diabetes, the target ranges may be different and will be determined by their healthcare provider. Generally, the targets for diabetics are:
- Fasting Blood Sugar: 80-130 mg/dL
- Postprandial Blood Sugar: Less than 180 mg/dL
- A1C: Less than 7.0% (as advised by doctor)

As we age, the body’s ability to regulate blood sugar may change due to factors like decreased physical activity, changes in diet, and the presence of other medical conditions. The target ranges for older adults without diabetes are generally:
- Fasting Blood Sugar: 80-110 mg/dL
- Postprandial Blood Sugar: Less than 140 mg/dL
- A1C: Less than 7.0% (For healthy older adults)
However, for older adults with diabetes, the target ranges might be more lenient, depending on their overall health and life expectancy. The goal is to balance good control with avoiding hypoglycemia. A healthcare provider can offer tailored advice.
Factors Affecting Blood Sugar Levels
Several factors can influence blood sugar levels:
- Diet: Consuming high amounts of sugary foods and refined carbohydrates can cause spikes in blood glucose.
- Physical Activity: Exercise helps improve insulin sensitivity and can lower blood sugar levels.
- Stress: Stress hormones can increase blood sugar levels.
- Medications: Certain medications can impact blood sugar. Corticosteroids, for example, can raise blood glucose.
- Illness: During an illness, the body may release stress hormones that raise blood sugar levels.
- Hormonal Changes: Fluctuations in hormones, particularly in women (menstruation, pregnancy, menopause), can impact blood sugar.
- Age: As mentioned earlier, blood sugar regulation can change as we age.
How to Maintain Healthy Blood Sugar Levels
Maintaining stable blood sugar levels requires a combination of lifestyle adjustments and careful monitoring:
-
Balanced Diet:
- Focus on a diet rich in fiber, whole grains, lean proteins, and healthy fats.
- Limit intake of processed foods, sugary drinks, and excessive carbohydrates.
- Eat regular meals and snacks to avoid drastic fluctuations in blood sugar.
-
Regular Exercise:
- Engage in at least 150 minutes of moderate-intensity aerobic exercise per week.
- Incorporate strength training exercises to improve insulin sensitivity.
- Consult a healthcare professional before starting a new exercise regimen.
-
Stress Management:
- Practice stress-reducing techniques such as yoga, meditation, or deep breathing exercises.
- Ensure adequate sleep to support hormonal balance and blood sugar regulation.
