What Are Normal Blood Sugar Levels by Age? (Complete Chart)
Understanding normal blood sugar levels is crucial for maintaining good health at any age. Fluctuations can indicate underlying health issues, like diabetes, that require proper management. This article breaks down the healthy ranges for blood sugar by age, providing a comprehensive overview and actionable insights for everyone, from children to seniors.
Why Blood Sugar Levels Matter
Blood sugar, also known as glucose, is the main source of energy for our bodies. It comes from the food we eat and is transported to cells via the bloodstream. Insulin, a hormone produced by the pancreas, helps glucose enter cells to be used for energy. When blood sugar levels are consistently too high (hyperglycemia) or too low (hypoglycemia), it can lead to serious health problems.
- Hyperglycemia (High Blood Sugar): Can damage blood vessels, nerves, and organs over time, leading to complications like heart disease, kidney disease, nerve damage (neuropathy), and vision problems (retinopathy).
- Hypoglycemia (Low Blood Sugar): Can cause shakiness, dizziness, confusion, and, in severe cases, loss of consciousness.
Therefore, knowing what constitutes a healthy range is essential for preventative care and early detection of potential issues.
Understanding Blood Sugar Readings: A Quick Guide
Before diving into the chart, let's define the key terms you'll encounter when checking your blood sugar:
- Fasting Blood Sugar: Measured after at least eight hours of not eating. This is commonly tested in the morning before breakfast.
- Postprandial Blood Sugar: Measured 1-2 hours after eating a meal. This reading reflects how your body processes glucose from food.
- A1C (Glycated Hemoglobin): Provides an average of your blood sugar levels over the past 2-3 months. It doesn't require fasting.
Normal Blood Sugar Levels by Age: A Comprehensive Chart
This chart provides general guidelines. Individual needs may vary. Always consult with a healthcare professional for personalized advice.
| Age Group | Fasting Blood Sugar (mg/dL) | Postprandial Blood Sugar (1-2 hours after eating) (mg/dL) | A1C (%) |
|---|---|---|---|
| Children (Under 6 years old) | 80-180 mg/dL | Up to 200 mg/dL | Less than 7.5% (Individual target determined by doctor) |
| Children (6-12 years old) | 80-120 mg/dL | Up to 140 mg/dL | Less than 7.5% (Individual target determined by doctor) |
| Teenagers (13-19 years old) | 70-150 mg/dL | Up to 140 mg/dL | Less than 7.5% (Individual target determined by doctor) |
| Adults (20-59 years old) | 70-99 mg/dL | Less than 140 mg/dL | Less than 5.7% |
| Seniors (60+ years old) | 80-150 mg/dL (Target ranges may be higher based on overall health) | Less than 180 mg/dL (Target ranges may be higher based on overall health) | Less than 7.0% (Individual target determined by doctor; could be higher based on health conditions) |
| People with Diabetes | 80-130 mg/dL (As recommended by your healthcare provider) | Less than 180 mg/dL (As recommended by your healthcare provider) | Less than 7.0% (As recommended by your healthcare provider; individual targets may vary) |

Factors Affecting Blood Sugar Levels
Many factors can influence blood sugar levels, including:

- Diet: High-carbohydrate and sugary foods can cause rapid spikes in blood sugar.
- Physical Activity: Exercise can help lower blood sugar by increasing insulin sensitivity and glucose uptake by muscles.
- Stress: Stress hormones can raise blood sugar levels.
- Medications: Certain medications, such as steroids, can affect blood sugar.
- Illness: Infections and other illnesses can temporarily increase blood sugar levels.
- Dehydration: Being dehydrated can affect blood sugar concentration.
Monitoring Your Blood Sugar: Methods and Tools
There are several ways to monitor your blood sugar:
- Blood Glucose Meter: Requires a small blood sample (usually from a fingertip) to measure blood sugar levels.
- Continuous Glucose Monitor (CGM): A small sensor inserted under the skin that continuously tracks blood sugar levels.
- A1C Test: Performed in a doctor's office or lab to provide an average blood sugar level over the past 2-3 months.
Regular monitoring allows individuals, especially those with diabetes, to make informed decisions about diet, exercise, and medication to maintain healthy blood sugar levels.
What to Do If Your Blood Sugar Is Too High or Too Low
It's crucial to know how to respond if your blood sugar falls outside the normal range.
For High Blood Sugar (Hyperglycemia):
- Drink Plenty of Water: Helps flush out excess glucose.
- Exercise (if safe): Physical activity can help lower blood sugar. However, avoid exercising if you have ketones in your urine, as this can be dangerous.
- Adjust Medication (if prescribed): Consult your doctor about adjusting your medication dosage.
- Check Your Diet: Evaluate what you’ve eaten recently and avoid foods that cause rapid blood sugar spikes.
For Low Blood Sugar (Hypoglycemia):
- Follow the 15-15 Rule: Consume 15 grams of fast-acting carbohydrates (e.g., glucose tablets, juice, regular soda) and check your blood sugar after 15 minutes. Repeat if your blood sugar is still too low.
- Have a Meal or Snack: Once your blood sugar is back within a normal range, eat a balanced meal or snack to prevent it from dropping again.
- Carry a Hypoglycemia Rescue Kit: Especially important for those prone to frequent low blood sugar episodes.

Preventing Blood Sugar Imbalances: Lifestyle Tips
Adopting a healthy lifestyle can significantly impact your ability to maintain stable blood sugar levels:
- Eat a Balanced Diet: Focus on whole, unprocessed foods, including plenty of fruits, vegetables, lean protein, and whole grains.
- Engage in Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity exercise per week.
- Maintain a Healthy Weight: Obesity is a major risk factor for insulin resistance and type 2 diabetes.
- Manage Stress: Practice stress-reducing techniques, such as yoga, meditation, or deep breathing exercises.
- Get Enough Sleep: Poor sleep can negatively impact blood sugar control. Aim for 7-8 hours of quality sleep per night.
- Stay Hydrated: Drink plenty of water throughout the day.
- Limit Alcohol Consumption: Alcohol can affect blood sugar levels, especially when consumed on an empty stomach.
The Importance of Regular Check-Ups
Regular check-ups with your healthcare provider are crucial for monitoring your overall health, including blood sugar levels. Screening for diabetes is recommended for individuals with risk factors, such as family history, obesity, or a sedentary lifestyle. Even if you don't have risk factors, routine blood sugar checks are generally recommended as part of preventive care.

Conclusion
Maintaining healthy blood sugar levels is essential for overall well-being at every stage of life. Understanding the normal ranges by age, being aware of the factors that can affect blood sugar, and adopting a healthy lifestyle can help prevent imbalances and reduce the risk of developing diabetes and other related complications. This comprehensive chart serves as a useful guide, but always consult with your healthcare provider for personalized advice and management strategies. By taking proactive steps, you can effectively manage your blood sugar and improve your long-term health outcomes.
