What Are Normal Blood Sugar Levels? The Definitive Chart for All Ages
Understanding normal blood sugar levels is crucial for maintaining good health, regardless of your age. Whether you’re concerned about diabetes, prediabetes, or simply want to optimize your well-being, this definitive chart will guide you. This article provides a comprehensive overview of what constitutes normal blood sugar at different times of the day and for various age groups. We’ll delve into the factors that influence these levels and when you should seek medical advice.
Why Monitoring Blood Sugar Levels Matters
Maintaining stable blood sugar levels is essential for several reasons:
- Energy Production: Glucose is the body’s primary source of energy. Consistent levels ensure a steady energy supply to your cells.
- Organ Function: Proper glucose regulation is vital for the optimal function of your brain, heart, and kidneys.
- Diabetes Prevention: Regularly monitoring your blood sugar can help detect prediabetes or diabetes early, allowing for timely intervention.
- Weight Management: Fluctuations in blood sugar can impact hunger and cravings, affecting your ability to maintain a healthy weight.

Before diving into the specifics, it's important to understand the common units used to measure blood sugar:
- mg/dL (milligrams per deciliter): This is the standard unit in the United States.
- mmol/L (millimoles per liter): This unit is used in most other countries.
You can convert between these units using the following formula:
- mg/dL = mmol/L x 18
- mmol/L = mg/dL / 18
Normal Blood Sugar Levels Chart for Adults (Non-Diabetic)
This chart provides general guidelines for adults without diabetes. Keep in mind that individual results may vary, and it's best to consult with a healthcare provider for personalized advice.
| Time | Normal Blood Sugar Level (mg/dL) | Normal Blood Sugar Level (mmol/L) |
|---|---|---|
| Fasting (Before Breakfast) | 70-99 | 3.9-5.5 |
| 2 Hours After Eating | Less than 140 | Less than 7.8 |
Normal Blood Sugar Levels for Children
Children's blood sugar levels are generally similar to those of adults, but slight variations may occur due to growth spurts and activity levels. Always consult a pediatrician for age-specific recommendations.
| Time | Normal Blood Sugar Level (mg/dL) | Normal Blood Sugar Level (mmol/L) |
|---|---|---|
| Fasting (Before Breakfast) | 70-100 | 3.9-5.5 |
| 2 Hours After Eating | Less than 140 | Less than 7.8 |
Normal Blood Sugar Levels for People with Diabetes
For individuals diagnosed with diabetes, blood sugar targets are different and require careful management to prevent complications. These targets are usually set by a healthcare professional.

- Stay Hydrated: Drink plenty of water throughout the day.
When to See a Doctor
It's important to consult a healthcare provider if you experience any of the following:
- Consistently high or low blood sugar readings.
- Symptoms of hyperglycemia (high blood sugar) such as increased thirst, frequent urination, and blurred vision.
- Symptoms of hypoglycemia (low blood sugar) such as shakiness, sweating, and confusion.
- Unexplained weight loss or gain.
- Family history of diabetes.
Blood Sugar Levels and Prediabetes
Prediabetes is a condition where blood sugar levels are higher than normal but not high enough to be diagnosed as diabetes. The following values indicate prediabetes:
- Fasting blood sugar: 100-125 mg/dL (5.6-6.9 mmol/L)
- 2-hour post-meal blood sugar: 140-199 mg/dL (7.8-11.0 mmol/L)
Early detection and lifestyle changes can often prevent prediabetes from progressing to type 2 diabetes.
Monitoring Blood Sugar During Pregnancy (Gestational Diabetes)
During pregnancy, it's essential to monitor blood sugar levels carefully due to the risk of gestational diabetes. Target ranges are usually stricter to protect both the mother and the baby. Your doctor will provide specific guidelines. Generally, the targets are:
- Fasting: 95 mg/dL or less
- 1 hour after a meal: 140 mg/dL or less
- 2 hours after a meal: 120 mg/dL or less
The Role of A1C Testing
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, especially for people with diabetes.
- Normal: Less than 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
