What Is a Normal Blood Sugar Level? The Ultimate Chart for All Ages
Understanding your blood sugar levels is crucial for maintaining overall health and preventing diabetes-related complications. Blood sugar, or glucose, is your body’s primary source of energy, derived from the food you eat. Maintaining a healthy blood sugar range ensures your body functions optimally. This article offers a comprehensive guide to normal blood sugar levels, covering different age groups, conditions (like pregnancy), and testing times, empowering you to take control of your health.
Why Monitoring Blood Sugar Levels Is Important
Monitoring your blood glucose is especially important for individuals with diabetes or those at risk of developing the condition. Regular monitoring helps:
- Manage Diabetes: Effectively track and adjust medication, diet, and exercise.
- Prevent Complications: Avoid hyperglycemia (high blood sugar) and hypoglycemia (low blood sugar), which can lead to serious health issues.
- Promote Healthy Lifestyle: Encourage better dietary habits and regular physical activity.
- Early Detection: Identify prediabetes or diabetes at an early stage, enabling timely intervention.

Normal Blood Sugar Levels Chart by Age Group
Normal blood sugar levels can vary based on age. Here's a detailed breakdown:
For Adults Without Diabetes
This chart provides a general guideline for adults without diabetes.
| Time of Day | Normal Range (mg/dL) | | --------------------- | ---------------------- | | Fasting | 70-99 | | 2 Hours After Eating | Less than 140 |
Note: These values can slightly vary based on individual factors and lab standards. Consult your healthcare provider for personalized guidance.
For Children Without Diabetes
Maintaining appropriate blood sugar levels is also important for children.
| Time of Day | Normal Range (mg/dL) | | --------------------- | ---------------------- | | Fasting | 70-100 | | 2 Hours After Eating | Less than 140 |
Note: Children's blood sugar levels can be influenced by growth spurts, physical activity, and diet. Regular check-ups are essential.
Blood Sugar Levels for People With Diabetes
Managing blood sugar is more complex for those with diabetes, requiring closer monitoring and adjustments.
| Time of Day | Target Range (mg/dL) | | --------------------- | ---------------------- | | Fasting | 80-130 | | 2 Hours After Eating | Less than 180 | | HbA1c | Less than 7% |
These targets may vary depending on individual health conditions and your doctor's recommendations.
Blood Sugar Levels During Pregnancy (Gestational Diabetes)

Pregnancy can affect blood sugar levels, leading to gestational diabetes in some women. This condition requires careful management to protect the health of both mother and baby.
| Time of Day | Target Range (mg/dL) | | --------------------- | ---------------------- | | Fasting | Less than 95 | | 1 Hour After Eating | Less than 140 | | 2 Hours After Eating | Less than 120 |
These targets are stricter to minimize risks associated with gestational diabetes.
Understanding the HbA1c Test
The HbA1c test provides a picture of your average blood sugar control over the past 2-3 months. It is a crucial tool for managing diabetes.
| HbA1c Level | Interpretation | | ----------- | ----------------------------------------------------------------------------------- | | Below 5.7% | Normal | | 5.7% - 6.4% | Prediabetes: Increased risk of developing diabetes | | 6.5% or Higher | Diabetes: Requires management through lifestyle changes, medication, or both |
What Causes High Blood Sugar (Hyperglycemia)?
Hyperglycemia can occur due to various factors:
- Diet: Consuming excessive amounts of carbohydrates.
- Inactivity: Lack of physical exercise.
- Illness: Infections or other illnesses can raise blood sugar.
- Medications: Certain medications, such as steroids, can affect blood sugar levels.
- Stress: High stress levels can increase blood sugar.
- Insufficient Insulin: Inadequate insulin production or resistance.
What Causes Low Blood Sugar (Hypoglycemia)?
Hypoglycemia can be triggered by:
- Skipping Meals: Going too long without eating.
- Excessive Insulin: Taking too much insulin or diabetes medication.
- Intense Exercise: Prolonged physical activity without adequate carbohydrate intake.
- Alcohol Consumption: Especially on an empty stomach.
- Certain Medical Conditions: Kidney or liver disorders.
