The Complete Blood Sugar Levels Chart by Age: What's Normal?
Related reading: A Guide To Normal Blood Sugar Levels By Age
Understanding your blood sugar levels is crucial for maintaining overall health and preventing diabetes. This article provides a comprehensive blood sugar levels chart broken down by age, explaining what’s considered normal, what’s not, and what you can do to maintain healthy levels. We'll explore everything from fasting blood sugar to postprandial (after-meal) glucose readings.
Why Monitor Blood Sugar Levels?

Monitoring your blood sugar, also known as glucose, is important for several reasons:
- Diabetes Prevention: Identifying prediabetes or early signs of diabetes allows for lifestyle changes to prevent or delay the onset of the disease.
- Diabetes Management: For those already diagnosed with diabetes (Type 1, Type 2, or Gestational), regular monitoring helps manage the condition, preventing complications.
- General Health Awareness: Even if you don't have diabetes, understanding your blood sugar levels can provide valuable insights into your metabolic health. Consistent high blood sugar can indicate insulin resistance and other underlying issues.
Key Blood Sugar Level Terms Explained
Before diving into the charts, let's define some key terms:
- Fasting Blood Sugar (FBS): Measured after at least 8 hours of fasting (usually overnight). This test gives a baseline reading of your glucose levels.
- Postprandial Blood Sugar (PPBS): Measured 1-2 hours after eating a meal. This test assesses how your body processes glucose after food intake.
- HbA1c (Glycated Hemoglobin): This test measures your average blood sugar levels over the past 2-3 months. It's a broader indicator of blood sugar control.
- Random Blood Sugar (RBS): Measured at any time of day, regardless of when you last ate. This test is often used to diagnose diabetes if symptoms are present.
Blood Sugar Levels Chart by Age Group
The following charts provide general guidelines for normal blood sugar ranges for different age groups. It's crucial to remember that individual targets may vary based on health conditions and treatment plans. Always consult with a healthcare professional for personalized advice.
Children and Adolescents (0-18 Years)
For children without diabetes:
Blood Sugar Test | Normal Range (mg/dL) |
---|---|
Fasting Blood Sugar (FBS) | 70-100 |
Postprandial Blood Sugar (PPBS) (1-2 hours after eating) | Less than 140 |
For children with diabetes, target ranges are often different and determined by their doctor. However, a general guideline for children and adolescents with type 1 diabetes:
Blood Sugar Test | Target Range (mg/dL) |
---|---|
Fasting Blood Sugar (FBS) | 70-150 |
Before Meals | 70-130 |
Postprandial Blood Sugar (PPBS) (1-2 hours after eating) | Less than 180 |
Adults (18-79 Years)
For adults without diabetes:

Blood Sugar Test | Normal Range (mg/dL) |
---|---|
Fasting Blood Sugar (FBS) | 70-99 |
Postprandial Blood Sugar (PPBS) (1-2 hours after eating) | Less than 140 |
HbA1c | Less than 5.7% |
For adults with diabetes, target ranges are individualized:
Blood Sugar Test | Target Range (mg/dL) |
---|---|
Fasting Blood Sugar (FBS) | 80-130 (Individualized) |
Postprandial Blood Sugar (PPBS) (1-2 hours after eating) | Less than 180 (Individualized) |
HbA1c | Less than 7.0% (Individualized) |
Seniors (80+ Years)
For seniors without diabetes: The target is the same as adults without diabetes. The goals for individuals with diabetes may need to be less strict due to concerns for severe hypoglycemia.
Blood Sugar Test | Target Range (mg/dL) - *General Guideline* |
---|---|
Fasting Blood Sugar (FBS) | 80-150 (Individualized; less strict target sometimes appropriate) |
Before Meals | 80-130 |
Postprandial Blood Sugar (PPBS) (1-2 hours after eating) | Less than 200 (Individualized; Less strict targets) |
HbA1c | Less than 8.0% (Individualized) |
Note: These are just general guidelines. Individualized blood sugar targets should be determined by a healthcare provider. For older adults, targets are often less strict, as frequent or severe hypoglycemia (low blood sugar) can be particularly dangerous.
Understanding Your Blood Sugar Readings
- Normal: Indicates healthy glucose metabolism.
- Prediabetes: Higher-than-normal blood sugar levels that aren’t yet high enough to be diagnosed as diabetes. This is a crucial time for lifestyle intervention.
- Diabetes: Significantly elevated blood sugar levels that require medical management.
Diagnostic Criteria for Diabetes
Test | Diabetes Diagnosis |
---|---|
Fasting Blood Sugar (FBS) | 126 mg/dL or higher on two separate tests |
HbA1c | 6.5% or higher |
Random Blood Sugar (RBS) | 200 mg/dL or higher, *with* symptoms of hyperglycemia |
Oral Glucose Tolerance Test (OGTT) | 200 mg/dL or higher after two hours |
Factors That Can Affect Blood Sugar Levels
Several factors can influence your blood sugar levels, including:

- Diet: The type and amount of carbohydrates you consume directly impact blood sugar.
- Physical Activity: Exercise helps lower blood sugar levels by increasing insulin sensitivity.
- Stress: Stress hormones can increase blood sugar.
- Illness: Infections and illnesses can temporarily raise blood sugar.
- Medications: Some medications, like steroids, can affect glucose levels.
- Age: As we age our insulin function may decline
How to Maintain Healthy Blood Sugar Levels
Whether you have diabetes, prediabetes, or are simply looking to improve your overall health, these tips can help:
- Eat a Balanced Diet: Focus on whole grains, lean proteins, fruits, and vegetables. Limit processed foods, sugary drinks, and excessive 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 prediabetes, regular monitoring is crucial.
- Manage Stress: Practice relaxation techniques like yoga, meditation, or deep breathing.
- Stay Hydrated: Drink plenty of water throughout the day.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep each night.
- Work with a Healthcare Professional: Discuss your blood sugar levels with your doctor and develop a personalized management plan.
When to Seek Medical Attention
Contact your doctor if you experience any of the following:
- Consistently high blood sugar levels
- Frequent episodes of hypoglycemia (low blood sugar)
- Symptoms of diabetes, such as increased thirst, frequent urination, unexplained weight loss, and blurred vision
- Signs of diabetic complications, such as nerve damage (neuropathy) or kidney problems (nephropathy).
Conclusion
Understanding the blood sugar levels chart by age is a vital step in proactive healthcare. By monitoring your blood sugar, adopting healthy lifestyle habits, and working closely with your healthcare provider, you can effectively manage your glucose levels and reduce your risk of developing diabetes and its complications.
