What Are Normal Blood Sugar Levels? The Ultimate Chart for All Ages
Understanding normal blood sugar levels is crucial for maintaining overall health and preventing or managing conditions like diabetes. Blood sugar, or glucose, provides energy for our cells, and keeping it within a healthy range is essential for optimal bodily function. This article will provide an in-depth look at blood sugar levels, what they mean, and how they vary across different age groups.
Why Monitor Blood Sugar Levels?
Monitoring your blood sugar levels helps in:
- Early detection of diabetes or prediabetes.
- Effective management of existing diabetes.
- Identifying the impact of diet and exercise on glucose levels.
- Preventing long-term complications associated with high or low blood sugar.
Understanding the Measurements
Before diving into the charts, it's important to understand the units of measurement used for blood sugar:
- mg/dL: Milligrams per deciliter. This is the standard measurement in the United States.
- mmol/L: Millimoles per liter. This is the standard measurement used in many other countries.
You'll find both units in the charts below for easy reference.

The following chart outlines the generally accepted normal blood sugar levels for adults without diabetes:
| Test | Normal Range (mg/dL) | Normal Range (mmol/L) |
|---|---|---|
| Fasting Blood Sugar (After 8 hours of fasting) | 70-99 mg/dL | 3.9-5.5 mmol/L |
| 2 Hours After Eating (Postprandial) | Less than 140 mg/dL | Less than 7.8 mmol/L |
| HbA1c (Average blood sugar over 2-3 months) | Less than 5.7% | N/A |
Blood Sugar Levels Chart for Adults with Diabetes
For individuals with diabetes, maintaining healthy blood sugar levels is crucial to avoid complications. These levels are often different from those without diabetes:
| Test | Target Range (mg/dL) | Target Range (mmol/L) |
|---|---|---|
| Fasting Blood Sugar (Before a meal) | 80-130 mg/dL | 4.4-7.2 mmol/L |
| 2 Hours After Eating (Postprandial) | Less than 180 mg/dL | Less than 10.0 mmol/L |
| HbA1c (Average blood sugar over 2-3 months) | Less than 7.0% (varies based on individual factors) | N/A |
Note: Target blood sugar levels may vary based on individual health conditions and treatment plans. Always consult your healthcare provider for personalized guidance.
Blood Sugar Levels in Children
Normal blood sugar levels in children can differ slightly from adults. Here’s a general guideline:
| Time | Target Range (mg/dL) for Children with Diabetes |
|---|---|
| Before Meals | 90-130 mg/dL |
| Bedtime | 90-150 mg/dL |
Important Note: This table is intended for children with diabetes. Healthy children without diabetes will typically have blood sugar levels similar to the adult non-diabetic range. Always consult a pediatrician for personalized advice on managing your child’s blood sugar.

Factors Influencing Blood Sugar Levels
Several factors can influence blood sugar levels, including:
- Diet: Carbohydrate intake has the most significant impact on blood sugar.
- Physical Activity: Exercise can lower blood sugar levels.
- Stress: Stress hormones can increase blood sugar.
- Medications: Certain medications can affect blood sugar levels.
- Illness: Infections and illnesses can raise blood sugar.
- Sleep: Insufficient sleep can impact insulin sensitivity.
What to Do If Your Blood Sugar Is High
If your blood sugar levels are consistently high, you should:
- Consult Your Doctor: Get a thorough medical evaluation.
- Adjust Your Diet: Reduce carbohydrate intake, especially sugary drinks and processed foods.
- Increase Physical Activity: Regular exercise helps lower blood sugar.
- Monitor Regularly: Track your blood sugar levels to identify patterns.
- Medication: If prescribed by your doctor, take your medications as directed.
What to Do If Your Blood Sugar Is Low (Hypoglycemia)
Low blood sugar, or hypoglycemia, can be dangerous. Symptoms include shakiness, sweating, dizziness, and confusion. If you experience hypoglycemia:
- Consume Fast-Acting Carbohydrates: Have 15-20 grams of fast-acting carbs, such as juice, glucose tablets, or hard candy.
- Recheck After 15 Minutes: Recheck your blood sugar after 15 minutes.
- Repeat if Necessary: If your blood sugar is still low, repeat the process.
- Seek Medical Help: If symptoms persist or worsen, seek immediate medical attention.
Preventing Blood Sugar Imbalances
Here are some tips for preventing blood sugar imbalances:
- Eat a Balanced Diet: Focus on whole, unprocessed foods.
- Exercise Regularly: Aim for at least 150 minutes of moderate-intensity exercise per week.
- Manage Stress: Practice stress-reduction techniques like yoga or meditation.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep per night.
- Regular Monitoring: Check your blood sugar regularly, especially if you have diabetes or are at risk.
The Role of HbA1c
The HbA1c test measures your average blood sugar levels over the past 2-3 months. It provides a more comprehensive picture than a single blood sugar reading. Aiming for a target HbA1c level can significantly reduce the risk of diabetes complications. A normal HbA1c is below 5.7%, while an HbA1c of 6.5% or higher indicates diabetes.
Conclusion
Understanding and maintaining normal blood sugar levels is vital for overall health. By regularly monitoring your blood sugar, adopting a healthy lifestyle, and consulting with healthcare professionals, you can effectively manage your glucose levels and reduce your risk of diabetes and its associated complications. Use this ultimate chart as a starting point, but always rely on personalized medical advice for the best results. Remember, proactive management of blood sugar can lead to a healthier and happier life.
