The Ultimate Blood Sugar Levels Chart (By Age, Fasting, and After Eating)
Understanding blood sugar levels is crucial for maintaining optimal health and preventing complications associated with diabetes. Whether you're monitoring your own glucose or caring for someone who is, knowing the target ranges for different situations – by age, fasting state, and after eating – is essential. This guide provides a comprehensive blood sugar levels chart and essential information for managing your health.
Why is Monitoring Blood Sugar Important?
Monitoring blood sugar levels helps in several ways:
- Early Detection: Identifying prediabetes and diabetes early allows for timely intervention.
- Effective Management: Individuals with diabetes can adjust medication, diet, and exercise based on their glucose readings.
- Preventing Complications: Maintaining stable blood sugar reduces the risk of long-term health problems, such as nerve damage, kidney disease, and heart disease.
- Improved Well-being: Fluctuations in blood sugar can affect energy levels, mood, and overall quality of life.
Understanding Blood Sugar Measurements
Blood sugar levels are typically measured in:
- mg/dL (milligrams per deciliter): The standard unit used in the United States.
- mmol/L (millimoles per liter): The unit used in many countries outside the U.S.
You can easily convert between the two using online converters. Knowing both measurements is helpful when encountering medical information from different sources.

Blood Sugar Levels Chart: By Age
Here's a detailed breakdown of target blood sugar levels for different age groups, which can slightly vary based on individual factors and medical advice. It's crucial to consult with a healthcare provider for personalized recommendations.
| Age Group | Fasting Blood Sugar (mg/dL) | 2 Hours After Eating (mg/dL) | A1C Target (%) |
|---|---|---|---|
| Children (Under 6) | 80-200 mg/dL | Up to 200 mg/dL | 7.5-8.5% |
| Children (6-12) | 80-180 mg/dL | Up to 180 mg/dL | 7.0-8.0% |
| Teenagers (13-19) | 70-150 mg/dL | Up to 140 mg/dL | 6.5-7.5% |
| Adults (Non-Diabetic) | 70-99 mg/dL | Less than 140 mg/dL | Less than 5.7% |
| Adults (Diabetic) | 80-130 mg/dL | Less than 180 mg/dL | Less than 7.0% (Adjusted per doctor's advice) |
| Older Adults (65+) | 80-150 mg/dL | Less than 180 mg/dL | 7.0-8.5% (Individualized based on health) |
Note: These are general guidelines and individual targets may vary. Always consult with a healthcare professional for personalized advice.
Fasting Blood Sugar Levels
Fasting blood sugar is measured after at least eight hours of not eating. This test is often used to screen for prediabetes and diabetes.
- Normal: Less than 100 mg/dL
- Prediabetes: 100-125 mg/dL
- Diabetes: 126 mg/dL or higher (on two separate tests)
If your fasting blood sugar falls into the prediabetes range, lifestyle changes like diet and exercise can often help prevent the development of type 2 diabetes.
Blood Sugar Levels After Eating (Postprandial)
Postprandial blood sugar is measured 1-2 hours after eating. This measurement helps assess how well your body processes glucose from food.

- Normal (1 Hour): Less than 180 mg/dL
- Normal (2 Hours): Less than 140 mg/dL
For people with diabetes, the target after-meal blood sugar is usually set by their healthcare provider and is often less than 180 mg/dL.
A1C: Long-Term Blood Sugar Control
The A1C test provides an average of your blood sugar levels over the past 2-3 months. It's a useful tool for monitoring long-term blood sugar control.
- Normal: Less than 5.7%
- Prediabetes: 5.7-6.4%
- Diabetes: 6.5% or higher
People with diabetes typically aim for an A1C of less than 7%, but the target may vary based on individual factors.
Factors Affecting Blood Sugar Levels
Several factors can influence blood sugar levels, including:

- Diet: The types and amounts of carbohydrates you consume directly affect blood sugar.
- Physical Activity: Exercise helps lower blood sugar by increasing insulin sensitivity and using glucose for energy.
- Medications: Insulin and other diabetes medications help regulate blood sugar.
- Stress: Stress hormones can raise blood sugar levels.
- Illness: Being sick can cause fluctuations in blood sugar.
- Hydration: Dehydration can impact blood sugar concentrations.
Tips for Maintaining Healthy Blood Sugar Levels
- Eat a Balanced Diet: Focus on whole grains, lean proteins, healthy fats, and plenty of fruits and vegetables. Limit sugary drinks and processed foods.
- Exercise Regularly: Aim for at least 150 minutes of moderate-intensity exercise per week.
- Monitor Blood Sugar Regularly: Check your blood sugar as directed by your healthcare provider.

- Get Enough Sleep: Aim for 7-8 hours of quality sleep each night.
- Follow Your Healthcare Provider’s Recommendations: Work with your doctor to develop a personalized diabetes management plan.
When to Seek Medical Attention
Seek medical attention if you experience any of the following:
- Hyperglycemia (High Blood Sugar): Consistently high blood sugar levels, especially if accompanied by symptoms like increased thirst, frequent urination, and blurred vision.
- Hypoglycemia (Low Blood Sugar): Blood sugar levels below 70 mg/dL, particularly if you experience symptoms like shakiness, sweating, confusion, and dizziness.
- Symptoms of Diabetic Ketoacidosis (DKA): Nausea, vomiting, abdominal pain, fruity-smelling breath, and rapid breathing.
- Unexplained Fluctuations: Frequent and significant swings in your blood sugar levels that are difficult to manage.
