Normal Blood Sugar Levels Chart by Age: What's Healthy for You?
Understanding your blood sugar levels is a key component of maintaining overall health and preventing or managing conditions like diabetes. But what's considered normal, and how does it vary by age? This comprehensive guide breaks down normal blood sugar levels for different age groups, explains why these levels matter, and provides actionable advice for maintaining healthy glucose levels.
Why Blood Sugar Levels Matter
Blood sugar, or glucose, is your body's primary source of energy. It comes from the food you eat. Insulin, a hormone produced by the pancreas, helps glucose enter your cells to be used for energy. When you have diabetes, either your body doesn't make enough insulin or can't effectively use the insulin it produces. This can lead to dangerously high or low blood sugar levels, which can have serious health consequences.
- Hyperglycemia (High Blood Sugar): Over time, high blood sugar can damage blood vessels, nerves, and organs, increasing the risk of heart disease, kidney disease, vision problems, and nerve damage (neuropathy).
- Hypoglycemia (Low Blood Sugar): Low blood sugar can cause symptoms like shakiness, sweating, confusion, and even loss of consciousness.
Regularly monitoring your blood glucose levels can help you and your doctor identify potential issues early on and take steps to manage your health effectively.
Normal Blood Sugar Levels Chart by Age
It's important to note that blood sugar levels are typically measured in milligrams per deciliter (mg/dL). These ranges can vary slightly depending on the source and individual health conditions. It's always best to consult with your doctor for personalized advice.
Here’s a general overview:
For Non-Diabetic Individuals
| Age Group | Fasting Blood Sugar (mg/dL) | 2 Hours After Eating (mg/dL) |
|---|---|---|
| Children (Under 6) | 80-180 | Up to 180 |
| Children (6-12) | 70-150 | Up to 140 |
| Teens (13-19) | 70-150 | Up to 140 |
| Adults (20+) | 70-99 | Up to 140 |
| Elderly (65+) | 80-110 | Up to 160 |
For Individuals with Diabetes
Target blood sugar levels for people with diabetes may differ from those without the condition. It's vital to collaborate with your healthcare provider to establish a personalized target range that aligns with your unique medical history and treatment strategy.
| Age Group | Fasting Blood Sugar (mg/dL) | 2 Hours After Eating (mg/dL) |
|---|---|---|
| Children (Under 6) | 80-200 | Up to 200 |
| Children (6-12) | 70-180 | Up to 180 |
| Teens (13-19) | 70-150 | Up to 180 |
| Adults (20+) | 80-130 | Less than 180 |
| Elderly (65+) | 90-150 | Less than 200 |

Note: These ranges are general guidelines. Individual targets may vary.
Understanding the Measurements
- Fasting Blood Sugar: This is measured after at least eight hours of fasting (no food or drink). It's often tested in the morning before breakfast.
- 2 Hours After Eating: This is measured two hours after the start of a meal. It indicates how well your body is processing glucose from the food you've eaten.
Factors That Affect Blood Sugar Levels
Many factors can influence your blood sugar levels. These include:
- Diet: Consuming high-carbohydrate or sugary foods can cause a rapid spike in blood sugar.
- Physical Activity: Exercise can help lower blood sugar by increasing insulin sensitivity and allowing your muscles to use glucose for energy.
- Stress: Stress hormones can increase blood sugar levels.
- Medications: Certain medications, like corticosteroids, can raise blood sugar.
- Illness: Infections or illnesses can affect blood sugar control.
- Sleep: Poor sleep can negatively impact blood sugar regulation.
- Age: As we age, insulin resistance tends to increase, affecting blood sugar.
- Dehydration: Dehydration can affect blood sugar levels, causing them to appear higher.
- Menstrual cycles: Hormonal fluctuations in women can affect blood sugar.
How to Maintain Healthy Blood Sugar Levels
Maintaining healthy blood sugar levels involves adopting lifestyle habits that support stable glucose levels. Here are some key strategies:

- Eat a Balanced Diet:
- Focus on whole, unprocessed foods like fruits, vegetables, lean proteins, and whole grains.
- Limit sugary drinks, processed snacks, and refined carbohydrates.
- Control your carbohydrate intake and pair carbs with protein and healthy fats to slow down glucose absorption.
- Engage in Regular Physical Activity:
- Aim for at least 150 minutes of moderate-intensity exercise per week.
- Include a mix of aerobic exercise (like walking, running, or swimming) and strength training.
- Monitor Your Blood Sugar:
- If you have diabetes, regularly monitor your blood sugar levels as recommended by your doctor.
- Keep a log of your readings to track patterns and trends.
- Manage Stress:
- Practice relaxation techniques like deep breathing, meditation, or yoga.
- Get enough sleep.
- Engage in hobbies and activities that you enjoy.
- Stay Hydrated:
- Drink plenty of water throughout the day.
- Aim for at least 8 glasses of water per day, unless otherwise instructed by a healthcare professional.
- Maintain a Healthy Weight:
- If you're overweight or obese, losing even a small amount of weight can improve insulin sensitivity and blood sugar control.
- Get Regular Check-Ups:
- See your doctor regularly for check-ups and blood sugar screenings, especially if you have risk factors for diabetes.
- Understand the Glycemic Index:
- Familiarize yourself with the glycemic index (GI) and glycemic load (GL) of different foods.
- Choose foods with a low GI and GL to help maintain more stable blood sugar levels.
- Consume Fiber-Rich Foods:
- Include plenty of fiber-rich foods in your diet, such as fruits, vegetables, whole grains, and legumes.
- Fiber can help slow down the absorption of glucose and improve blood sugar control.
When to See a Doctor
It's essential to consult a doctor if you experience:

- Frequent symptoms of high or low blood sugar, such as increased thirst, frequent urination, unexplained weight loss, blurred vision, fatigue, or slow-healing sores.
- If you have a family history of diabetes and are concerned about your risk.
- If you're experiencing unusual or persistent changes in your blood sugar levels.
A doctor can perform a thorough evaluation, including blood sugar tests, and provide personalized recommendations for managing your health.
Blood Sugar Testing Methods
There are several methods for monitoring blood sugar levels:
- Fasting Plasma Glucose (FPG) Test: Measures blood sugar after an overnight fast.
- Oral Glucose Tolerance Test (OGTT): Measures blood sugar after fasting and then two hours after drinking a sugary drink. It is often used to diagnose gestational diabetes.
- A1C Test: Measures your average blood sugar level over the past 2-3 months.
- Self-Monitoring of Blood Glucose (SMBG): Using a blood glucose meter to check your blood sugar at home.
- Continuous Glucose Monitoring (CGM): Wearing a device that continuously monitors your blood sugar throughout the day and night.
Conclusion
Understanding normal blood sugar levels by age is essential for maintaining good health and preventing or managing diabetes. While these charts provide general guidelines, it's crucial to remember that individual needs can vary. By adopting healthy lifestyle habits, regularly monitoring your blood sugar, and consulting with your healthcare provider, you can effectively manage your blood sugar levels and support your overall well-being. This knowledge will help you make informed decisions about your diet and lifestyle to support healthy blood sugar.
