The Ultimate Blood Sugar Levels Chart by Age: Your Complete Guide
Maintaining healthy blood sugar levels is crucial for overall well-being, and understanding what's considered "normal" varies with age. This comprehensive guide provides a detailed blood sugar levels chart, specifically broken down by age group, along with essential information on what affects these levels and how to manage them effectively. Whether you're concerned about diabetes, prediabetes, or simply want to optimize your health, this article has you covered.
Why Blood Sugar Levels Matter
Blood sugar, or glucose, is the main sugar found in your blood, and it comes from the food you eat. Your body uses glucose for energy. The pancreas produces a hormone called insulin, which helps glucose get from your blood into your cells. When blood sugar levels are consistently too high (hyperglycemia) or too low (hypoglycemia), it can lead to serious health problems.
- Hyperglycemia (High Blood Sugar): Over time, high blood sugar can damage your heart, blood vessels, kidneys, and nerves.
- Hypoglycemia (Low Blood Sugar): Low blood sugar can cause dizziness, confusion, and even loss of consciousness.
Understanding and managing your blood sugar levels is therefore essential for preventing these complications.
Blood Sugar Levels Chart by Age Group
It's important to note that these numbers are general guidelines and individual targets may vary depending on health conditions and recommendations from a healthcare provider.
| Age Group | Fasting Blood Sugar (mg/dL) | 2 Hours After Eating (mg/dL) | A1C (%) |
|---|---|---|---|
| Children (Under 6) | 80-180 | Up to 200 | N/A (not primary measure) |
| Children (6-12) | 80-120 | Up to 140 | Less than 7.5% (typical goal for those with diabetes) |
| Teenagers (13-19) | 70-150 | Up to 140 | Less than 7.5% (typical goal for those with diabetes) |
| Adults (20-59) Without Diabetes | 70-99 | Less than 140 | Less than 5.7% |
| Adults (20-59) With Diabetes | 80-130 | Less than 180 | Less than 7% (often, but varies by individual) |
| Seniors (60+) Without Diabetes | 70-100 | Less than 140 | Less than 6.5% |
| Seniors (60+) With Diabetes | 80-150 | Less than 180 | Less than 8% (can be higher, depending on overall health) |
Important Definitions:
- Fasting Blood Sugar: Blood sugar level measured after at least eight hours of fasting (no food or drinks other than water).
- 2 Hours After Eating: Blood sugar level measured two hours after the start of a meal.
- A1C: A blood test that reflects average blood sugar levels over the past 2-3 months. It's a key measure for diabetes management.

Factors Affecting Blood Sugar Levels
Numerous factors can influence your blood sugar levels, including:
- Diet: The type and amount of carbohydrates you consume have the most direct impact. High-sugar and processed foods cause rapid spikes.
- Physical Activity: Exercise helps lower blood sugar by increasing insulin sensitivity and burning glucose for energy.
- Stress: Stress hormones can raise blood sugar levels.
- Medications: Certain medications, such as steroids and some diuretics, can affect blood sugar.
- Illness: Infections can cause blood sugar to fluctuate.
- Sleep: Poor sleep quality can affect insulin sensitivity and increase blood sugar.
- Age: As we age, our bodies may become less efficient at regulating blood sugar.
- Dehydration: Can lead to concentrated blood sugar levels.
How to Monitor Your Blood Sugar
Regular blood sugar monitoring is crucial, especially for individuals with diabetes or prediabetes. Here are the common methods:
- Blood Glucose Meter: This involves pricking your finger with a lancet and using a meter to measure the blood sugar level.
- Continuous Glucose Monitor (CGM): A CGM is a device that continuously tracks glucose levels through a small sensor inserted under the skin. This provides a dynamic view of blood sugar trends.
- A1C Test: As mentioned, this test provides an average blood sugar level over the past 2-3 months and is typically performed in a doctor's office.

Effective management of blood sugar levels involves lifestyle modifications and, in some cases, medication.
- Dietary Changes:
- Choose complex carbohydrates over simple sugars (e.g., whole grains, vegetables, fruits).
- Limit processed foods, sugary drinks, and sweets.
- Eat regular, balanced meals and snacks.
- Focus on fiber-rich foods to slow down glucose absorption.
- Regular Exercise: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Weight Management: Maintaining a healthy weight can improve insulin sensitivity.
- Stress Management: Practice relaxation techniques such as yoga, meditation, or deep breathing.
- Medication: If lifestyle changes are not enough, your doctor may prescribe medications, such as insulin or oral hypoglycemic agents.
- Adequate Sleep: Aim for 7-9 hours of quality sleep each night.
- Stay Hydrated: Drink plenty of water throughout the day.
When to Seek Medical Attention
It's crucial to seek medical attention if you experience any of the following:
- Frequent high or low blood sugar levels.
- Symptoms of hyperglycemia or hypoglycemia (excessive thirst, frequent urination, blurred vision, fatigue, dizziness, confusion, seizures).
- Unexplained weight loss.
- Persistent infections.
- Any concerns about your blood sugar levels or overall health.

Prediabetes is a condition where blood sugar levels are higher than normal but not high enough to be diagnosed as diabetes. Many people with prediabetes develop type 2 diabetes within a few years if they don't make lifestyle changes. Prediabetes is often diagnosed based on these criteria:
- Fasting Blood Sugar: 100-125 mg/dL
- A1C: 5.7-6.4%
Early intervention through diet, exercise, and weight loss can help prevent or delay the onset of type 2 diabetes.
Conclusion
Understanding your blood sugar levels and how they fluctuate throughout life is a critical step towards maintaining optimal health. Use this blood sugar levels chart as a reference, but remember to consult with your healthcare provider for personalized guidance. By making informed choices about your diet, exercise, and lifestyle, you can effectively manage your blood sugar and reduce your risk of developing diabetes and other related complications.
