What is a Normal Blood Sugar Level? The Ultimate Chart by Age
Understanding normal blood sugar levels is crucial for maintaining good health and preventing serious complications like diabetes. This guide provides a comprehensive overview of healthy blood sugar ranges for different age groups, explaining what factors influence these levels and offering insights into when to seek medical advice.
Why Blood Sugar Levels Matter
Blood sugar, or glucose, is the primary source of energy for the body. Insulin, a hormone produced by the pancreas, helps transport glucose from the bloodstream into cells for energy. When blood sugar levels are consistently too high (hyperglycemia) or too low (hypoglycemia), it can lead to various health problems. Monitoring blood sugar helps you understand how your body is processing glucose.
What Factors Influence Blood Sugar Levels?
Several factors can affect your blood sugar levels, including:

- Diet: Consuming sugary foods and refined carbohydrates can cause a rapid spike in blood sugar.
- Physical Activity: Exercise helps lower blood sugar as muscles use glucose for energy.
- Stress: Stress hormones can raise blood sugar levels.
- Medications: Certain medications, such as steroids, can increase blood sugar.
- Underlying Medical Conditions: Conditions like diabetes, pancreatitis, and hormonal imbalances can affect blood sugar regulation.
- Age: Normal blood sugar varies with age.
- Time of Day: Blood sugar level typically varies depending on the meal times and whether you are fasting or not.
The Ultimate Blood Sugar Chart by Age
Here’s a detailed breakdown of normal blood sugar levels for different age groups. Remember that these are general guidelines, and individual targets may vary based on specific health conditions and physician recommendations.
| Age Group | Fasting Blood Sugar (mg/dL) | 2 Hours After Meal (mg/dL) | A1C (%) |
|---|---|---|---|
| Children (Under 6 years) | 80-180 | Up to 200 | N/A (Specific targets set by doctor) |
| Children (6-12 years) | 80-120 | Up to 140 | N/A (Specific targets set by doctor) |
| Teenagers (13-19 years) | 70-110 | Up to 140 | N/A (Specific targets set by doctor) |
| Adults (20-59 years) | 70-100 | Up to 140 | Below 5.7% |
| Seniors (60+ years) | 80-110 | Up to 160 | Below 7.0% (Can vary; consult with doctor) |
Note: These values are general guidelines. Individuals with diabetes will have different target ranges set by their healthcare provider. Always consult with a doctor to determine the appropriate blood sugar level goals for your specific health situation. The A1C test measures average blood sugar levels over the past 2-3 months.
Understanding the Blood Sugar Ranges
- Fasting Blood Sugar: This is the blood sugar level after not eating or drinking anything (except water) for at least eight hours. It’s often measured in the morning before breakfast.
- 2 Hours After Meal: This measurement is taken two hours after the start of a meal and provides insights into how your body processes glucose after eating.
- A1C (Glycated Hemoglobin): The A1C test provides an average of your blood sugar control over the past 2-3 months. It reflects the percentage of your red blood cells that have glucose attached to them. Higher A1C levels indicate poorer blood sugar control.
What is Considered High Blood Sugar (Hyperglycemia)?
High blood sugar, or hyperglycemia, occurs when your blood sugar level is above the normal range. Consistently high blood sugar levels can lead to long-term health complications, including:
- Heart disease
- Kidney damage
- Nerve damage (neuropathy)
- Eye damage (retinopathy)
Symptoms of high blood sugar may include:
- Increased thirst
- Frequent urination
- Blurred vision
- Fatigue
- Slow-healing sores
If you frequently experience these symptoms or if your blood sugar levels consistently exceed the recommended ranges, consult with your healthcare provider.
What is Considered Low Blood Sugar (Hypoglycemia)?
Low blood sugar, or hypoglycemia, occurs when your blood sugar level falls below the normal range (typically below 70 mg/dL). Hypoglycemia can be dangerous and requires prompt treatment.
Symptoms of low blood sugar may include:
- Shakiness
- Sweating
- Dizziness
- Confusion
- Irritability
- Rapid heartbeat
If you experience symptoms of low blood sugar, eat or drink something sugary (such as glucose tablets, juice, or hard candy) immediately. If left untreated, severe hypoglycemia can lead to seizures, loss of consciousness, and even death.

How to Maintain Healthy Blood Sugar Levels
Maintaining healthy blood sugar levels involves a combination of lifestyle modifications and medical management. Here are some strategies:
- Follow a Balanced Diet: Focus on whole, unprocessed foods, including fruits, vegetables, lean proteins, and whole grains. Limit sugary drinks, refined carbohydrates, and saturated fats.
- Engage in Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity exercise per week. Exercise helps improve insulin sensitivity and lower blood sugar.
- Monitor Your Blood Sugar Regularly: If you have diabetes or are at risk for developing it, monitoring your blood sugar levels is crucial. Use a blood sugar meter as directed by your healthcare provider.
- Manage Stress: Practice relaxation techniques, such as meditation, yoga, or deep breathing exercises, to help manage stress levels.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep per night. Poor sleep can affect blood sugar control.
- Stay Hydrated: Drink plenty of water throughout the day. Dehydration can affect blood sugar levels.
- Consult with Your Healthcare Provider: Work closely with your doctor or a registered dietitian to develop a personalized plan for managing your blood sugar.
