The Ultimate Blood Sugar Levels Chart by Age (For Non-Diabetics & Diabetics)
Understanding blood sugar levels is critical for maintaining good health, especially for those with diabetes. But what are considered normal or healthy ranges? What about the differences in blood sugar by age? This comprehensive guide provides the ultimate blood sugar levels chart by age, covering both non-diabetics and diabetics to help you better manage your health.
Why is Monitoring Blood Sugar Important?
Maintaining healthy blood sugar levels is essential for overall well-being. Chronically high blood sugar, known as hyperglycemia, can lead to serious health complications, including:
- Heart disease
- Kidney disease
- Nerve damage (neuropathy)
- Eye damage (retinopathy)
Conversely, low blood sugar (hypoglycemia) can also be dangerous, causing symptoms like dizziness, confusion, and even seizures. Regular blood sugar monitoring helps individuals take proactive steps to maintain their health and prevent these complications. For individuals with diabetes, consistent monitoring is vital for managing their condition effectively.
Understanding Key Blood Sugar Metrics
Before diving into the charts, it's helpful to understand the different blood sugar measurements you'll encounter:
- Fasting Blood Sugar (FBS): This is the blood sugar level measured after an overnight fast (usually at least 8 hours).
- Postprandial Blood Sugar (PPBS): This is the blood sugar level measured 1-2 hours after eating a meal.
- HbA1c (Glycated Hemoglobin): This test provides an average of your blood sugar levels over the past 2-3 months. It's a critical metric for assessing long-term blood sugar control.
- Random Blood Sugar (RBS): This is blood sugar level measured at any time of the day, regardless of when you last ate. It’s often used to diagnose diabetes when symptoms are present.
Blood Sugar Levels Chart for Non-Diabetics (by Age)
Generally, non-diabetic blood sugar levels remain within a relatively tight range. However, slight variations can occur based on age. Below is a general guideline. Remember, it's essential to consult with a healthcare professional for personalized advice.

| Age Group | Fasting Blood Sugar (mg/dL) | 2-Hour Postprandial (mg/dL) | HbA1c (%) |
|---|---|---|---|
| Children & Adolescents | 70-100 | Less than 140 | Less than 5.7 |
| Adults (Under 60) | 70-100 | Less than 140 | Less than 5.7 |
| Older Adults (60+) | 80-110 | Less than 160 | Less than 6.5 (often targeted higher) |
Important Considerations for Non-Diabetics: These are general guidelines. Age-related changes in metabolism and activity levels might slightly affect these ranges. Always consult a healthcare provider for personalized advice and blood sugar monitoring recommendations.
Blood Sugar Levels Chart for Diabetics (by Age)
For individuals with diabetes (Type 1, Type 2, or gestational), target blood sugar ranges may differ from those of non-diabetics. The American Diabetes Association (ADA) and other organizations provide general guidelines, but individual targets should be determined in consultation with a doctor.

| Age Group | Fasting Blood Sugar (mg/dL) | 2-Hour Postprandial (mg/dL) | HbA1c (%) |
|---|---|---|---|
| Children (Type 1 Diabetes) | 70-150 | Less than 180 | Less than 7.5 (or individualized) |
| Adults (Type 1 & Type 2 Diabetes) | 80-130 | Less than 180 | Less than 7.0 (or individualized) |
| Older Adults (Type 2 Diabetes) | 90-150 (flexible based on health) | Less than 200 (flexible based on health) | Less than 8.0 (or individualized, may be higher) |
| Gestational Diabetes | Less than 95 | Less than 120 | N/A (targets based on daily glucose readings) |

Key Notes for Diabetics:
- Individualized Targets: Blood sugar targets can vary based on several factors, including age, overall health, diabetes type, and risk of hypoglycemia. Always work closely with your healthcare team to establish personalized goals.
- Continuous Glucose Monitoring (CGM): CGM devices provide real-time blood sugar readings, empowering individuals with diabetes to make proactive adjustments to their diet, activity, and medication. This is particularly useful for managing postprandial spikes.
- Hypoglycemia Awareness: Be aware of the signs of low blood sugar (shakiness, sweating, confusion). Carry a source of fast-acting carbohydrates (glucose tablets, juice) at all times.
Factors That Affect Blood Sugar Levels
Many factors can influence your blood sugar levels, including:
- Diet: The type and amount of carbohydrates you consume have a direct impact. Focus on complex carbohydrates, fiber-rich foods, and portion control.
- Physical Activity: Exercise helps lower blood sugar by increasing insulin sensitivity. Aim for at least 150 minutes of moderate-intensity exercise per week.
- Stress: Stress hormones can raise blood sugar levels. Practice stress-reducing techniques such as meditation or yoga.
- Medications: Certain medications, including steroids and some antidepressants, can affect blood sugar.
- Illness: When you're sick, your body releases hormones to fight the infection, which can increase blood sugar levels.
- Dehydration: Dehydration can concentrate blood sugar, leading to higher readings.
- Menstrual Cycle: Hormonal fluctuations during the menstrual cycle can impact blood sugar levels in women.
Practical Tips for Maintaining Healthy Blood Sugar Levels
Regardless of whether you are diabetic or not, here are some practical tips for maintaining healthy blood sugar levels:
- Eat a balanced diet: Focus on whole, unprocessed foods, including fruits, vegetables, lean proteins, and complex carbohydrates.
- Stay hydrated: Drink plenty of water throughout the day.
- 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, check your blood sugar levels regularly as directed by your doctor.
- Manage stress: Practice stress-reducing techniques such as meditation, yoga, or spending time in nature.
- Get enough sleep: Aim for 7-8 hours of quality sleep each night.
- Limit alcohol consumption: Alcohol can affect blood sugar levels, especially if you have diabetes.
- Quit smoking: Smoking can increase insulin resistance and raise your risk of diabetes complications.
When to See a Doctor
It's important to see a doctor if you experience any of the following:
- Frequent urination
- Excessive thirst
- Unexplained weight loss
- Blurred vision
- Slow-healing sores
- Frequent infections
- Numbness or tingling in your hands or feet
These symptoms may indicate that you have diabetes or prediabetes. Early diagnosis and treatment can help prevent serious health complications. If you're already diagnosed with diabetes, consult your doctor regularly to manage your condition effectively and adjust your treatment plan as needed. Pay particular attention to the HbA1c test to monitor long-term blood sugar control.
The Importance of Regular Check-ups and Professional Advice
This blood sugar levels chart provides a general overview, but remember that individual needs can vary. Regular check-ups with your healthcare provider are crucial for monitoring your blood sugar and overall health. A healthcare professional can provide personalized recommendations based on your individual circumstances and medical history. Don't rely solely on online information; use it as a supplement to professional medical advice. Understanding your blood sugar is a key step in taking control of your health and well-being.
