The Complete Blood Sugar Levels Chart by Age (and What It Means)
Understanding blood sugar levels is crucial for maintaining good health at any age. Whether you're monitoring for diabetes, pre-diabetes, or simply curious about your body's glucose regulation, knowing the ideal ranges and what deviations mean is essential. This article provides a comprehensive blood sugar levels chart by age, explaining the significance of each range and offering insights into managing your glucose effectively.
Why Monitor Blood Sugar Levels?
Blood sugar, or glucose, is the main sugar found in your blood and comes from the food you eat. It's your body's primary source of energy. Monitoring blood sugar levels helps:
- Detect and manage diabetes.
- Identify pre-diabetes and take steps to prevent the onset of diabetes.
- Ensure that prescribed medications are effective.
- Understand how diet and exercise affect glucose levels.
- Optimize overall health and well-being.
Regular monitoring, especially for those at risk or diagnosed with diabetes, empowers you to make informed decisions about your lifestyle and treatment plans.
Understanding Blood Sugar Measurements
Blood sugar levels are typically measured in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). The measurements are taken at different times to provide a complete picture:
- Fasting Blood Sugar (FBS): Measured after at least eight hours of fasting (no food or drink except water).
- Postprandial Blood Sugar (PPBS): Measured two hours after starting a meal.
- HbA1c (Glycated Hemoglobin): Measures your average blood sugar levels over the past two to three months. This doesn’t require fasting.
- Random Blood Sugar (RBS): Measured at any time, regardless of when you last ate.
Blood Sugar Levels Chart by Age
This chart provides general guidelines for blood sugar levels. Individual targets may vary based on specific health conditions, medication, and lifestyle factors. Always consult your healthcare provider for personalized advice.
| Age Group | Fasting Blood Sugar (mg/dL) | 2-Hour Postprandial Blood Sugar (mg/dL) | HbA1c (%) |
|---|---|---|---|
| Children (Under 6 years) | 80-200 | Up to 200 | 6.0-8.5 |
| Children (6-12 years) | 70-150 | Up to 180 | 6.0-8.0 |
| Teenagers (13-19 years) | 70-150 | Up to 140 | 6.0-7.5 |
| Adults (20+ years) - Non-Diabetic | 70-99 | Less than 140 | Less than 5.7% |
| Adults (20+ years) - Diabetic | 80-130 | Less than 180 | Less than 7.0% (target may vary) |
| Elderly (65+ years) | 80-180 | Up to 180 | Less than 7.5% (target may vary) |
Note: This table provides general guidelines and should not be used for self-diagnosis or treatment. Individual targets may vary.
Blood Sugar Levels and Their Meanings
Normal Blood Sugar Levels
- Fasting Blood Sugar: For most adults without diabetes, a normal fasting blood sugar is between 70-99 mg/dL.
- Postprandial Blood Sugar: A normal 2-hour postprandial blood sugar is less than 140 mg/dL.
- HbA1c: A normal HbA1c level is less than 5.7%.
High Blood Sugar Levels (Hyperglycemia)
High blood sugar levels occur when the body doesn't have enough insulin or can't effectively use the insulin it has. Common causes include diabetes, overeating, inactivity, stress, and certain medications.
- Fasting Blood Sugar: 100-125 mg/dL indicates pre-diabetes, while 126 mg/dL or higher on two separate tests indicates diabetes.
- Postprandial Blood Sugar: 140-199 mg/dL indicates pre-diabetes, while 200 mg/dL or higher indicates diabetes.
- HbA1c: 5.7-6.4% indicates pre-diabetes, while 6.5% or higher indicates diabetes.
Symptoms of hyperglycemia can include:
- Frequent urination
- Increased thirst
- Blurred vision
- Fatigue
- Headaches
Untreated hyperglycemia can lead to serious complications such as diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar state (HHS).
Low Blood Sugar Levels (Hypoglycemia)
Low blood sugar levels, or hypoglycemia, occur when glucose levels fall below 70 mg/dL. This can be caused by excessive insulin, skipped meals, intense exercise, alcohol consumption, and certain medical conditions.
Symptoms of hypoglycemia can include:
- Shakiness
- Sweating
- Anxiety
- Dizziness
- Confusion
- Rapid heartbeat
Severe hypoglycemia can lead to seizures, loss of consciousness, and even death if not treated promptly.
Factors Influencing Blood Sugar Levels
Several factors can influence your blood sugar levels, including:

- Diet: The type and amount of carbohydrates you consume directly impact glucose levels.
- Exercise: Physical activity helps lower blood sugar by increasing insulin sensitivity.
- Stress: Stress hormones can increase blood sugar levels.
- Medications: Certain medications, such as corticosteroids, can raise blood sugar levels.
- Illness: Illness and infection can affect glucose control.
- Hormonal Changes: Hormonal fluctuations during menstruation or pregnancy can impact blood sugar levels.
- Age: As you age, your body's ability to regulate blood sugar may decline.
How to Maintain Healthy Blood Sugar Levels
Maintaining healthy blood sugar levels involves a combination of lifestyle modifications and, in some cases, medication.
- Balanced Diet: Focus on a diet rich in whole grains, lean proteins, fruits, and vegetables. Limit processed foods, sugary drinks, and excessive carbohydrate intake.
- Regular Exercise: Aim for at least 150 minutes of moderate-intensity aerobic exercise per week, along with strength training exercises.
- Weight Management: Maintaining a healthy weight can improve insulin sensitivity and help regulate blood sugar levels.
- Stress Management: Practice relaxation techniques such as yoga, meditation, or deep breathing exercises to manage stress levels.
- Medication: If prescribed medication for diabetes, take it as directed by your healthcare provider.
- Regular Monitoring: Monitor your blood sugar levels regularly and keep a record of your readings.
- Adequate Sleep: Aim for 7-8 hours of quality sleep each night.
Special Considerations for Different Age Groups
While the blood sugar levels chart provides general guidelines, here are specific considerations for different age groups:
Children and Teenagers
Managing blood sugar levels in children and teenagers can be particularly challenging due to growth spurts, hormonal changes, and varying activity levels. Parents should work closely with healthcare providers to develop a personalized diabetes management plan that includes diet, exercise, and insulin therapy if necessary. Focus should be on healthy eating habits early in life.
Pregnant Women
Gestational diabetes, which develops during pregnancy, can increase the risk of complications for both the mother and the baby. Pregnant women are typically screened for gestational diabetes between 24 and 28 weeks of gestation. Maintaining optimal blood sugar levels during pregnancy is crucial for a healthy pregnancy and delivery.
Elderly Adults

Older adults may have a higher risk of hypoglycemia due to impaired kidney function, cognitive decline, and multiple medications. Individualized treatment plans are important, balancing tight blood sugar control with minimizing the risk of hypoglycemia.
When to See a Doctor
Consult your healthcare provider if you experience any of the following:
- Frequent episodes of hyperglycemia or hypoglycemia.
- Symptoms of diabetes, such as increased thirst, frequent urination, or unexplained weight loss.
- Difficulty managing your blood sugar levels despite following a prescribed treatment plan.
- Concerns about your blood sugar levels or diabetes management.
Conclusion
Understanding and monitoring your blood sugar levels is a key component of overall health and well-being. The blood sugar levels chart by age provides a helpful guide for determining what's normal, but it's crucial to consult with your healthcare provider for personalized advice and management. By adopting healthy lifestyle habits and following a tailored treatment plan, you can effectively manage your glucose levels and reduce your risk of diabetes-related complications. Remember, regular monitoring and proactive management are essential for maintaining healthy blood sugar throughout your life.
