Your Guide to Normal Blood Sugar Levels: A Simple Chart for Adults
Understanding normal blood sugar levels is crucial for maintaining overall health, especially for adults. Whether you're monitoring for potential diabetes, managing an existing condition, or simply curious, this guide provides a comprehensive overview, including a simple chart for easy reference. We'll explore what normal blood sugar ranges are, what factors can affect them, and when to seek medical advice.
What are Blood Sugar Levels?
Blood sugar, also known as blood glucose, refers to the concentration of glucose in your blood. Glucose is a primary source of energy for your body, and it comes from the food you eat. Insulin, a hormone produced by the pancreas, helps glucose move from your bloodstream into your cells, where it can be used for energy or stored for later use.

Normal blood sugar levels fluctuate throughout the day, depending on factors like when you last ate, what you ate, and your activity level. Consistently high or low blood sugar levels can be indicative of underlying health issues, most notably diabetes. Understanding The Link Between Insulin And Blood Sugar Management
Why is Monitoring Blood Sugar Important?
Monitoring your blood sugar levels is vital for several reasons:
- Early Detection of Diabetes: Regular monitoring can help identify prediabetes or diabetes in its early stages, allowing for timely intervention.
- Effective Diabetes Management: For individuals with diabetes, consistent monitoring is essential for managing the condition effectively and preventing complications.
- Lifestyle Adjustments: Tracking blood sugar levels can help you understand how different foods, activities, and stress levels affect your body, enabling you to make informed lifestyle choices.
- Preventing Complications: Maintaining healthy blood sugar levels can reduce the risk of serious complications associated with diabetes, such as heart disease, nerve damage, and kidney disease.
Normal Blood Sugar Levels Chart for Adults
The following chart outlines the generally accepted normal blood sugar ranges for adults without diabetes, measured in milligrams per deciliter (mg/dL). These values may vary slightly depending on the lab and your healthcare provider's recommendations. Always consult with a healthcare professional for personalized advice.
| Time of Day | Normal Blood Sugar Range (mg/dL) |
|---|---|
| Fasting (after at least 8 hours of not eating) | 70-99 mg/dL |
| 2 Hours After Eating | Less than 140 mg/dL |
Important Considerations:
- Fasting Blood Sugar: This is the blood sugar level measured after at least eight hours of fasting. It's a common test for detecting diabetes and prediabetes.
- Postprandial Blood Sugar: This refers to the blood sugar level measured two hours after eating a meal. It helps assess how your body responds to food.
Blood Sugar Levels for People with Diabetes
For individuals diagnosed with diabetes, the target blood sugar levels are typically different. The American Diabetes Association (ADA) provides the following guidelines:
| Time of Day | Target Blood Sugar Range (mg/dL) for Diabetics |
|---|---|
| Fasting (before a meal) | 80-130 mg/dL |
| 2 Hours After Eating | Less than 180 mg/dL |
It's important to note that these are general guidelines, and your healthcare provider may recommend different targets based on your individual health status and diabetes management plan.
Factors That Can Affect Blood Sugar Levels
Several factors can influence your blood sugar levels, including:
- Food: The type and amount of carbohydrates you consume significantly impact blood sugar levels. High-carb foods tend to raise blood sugar more rapidly.
- Physical Activity: Exercise can lower blood sugar as your muscles use glucose for energy.
- Medications: Certain medications, such as steroids and diuretics, can affect blood sugar levels.
- Stress: Stress hormones can raise blood sugar levels.
- Illness: Infections and illnesses can also lead to elevated blood sugar levels.
- Dehydration: Being dehydrated can concentrate glucose in your blood, leading to higher readings.
- Sleep: Poor sleep can affect insulin sensitivity and raise blood sugar levels.
- Menstrual Cycle: Hormonal changes during the menstrual cycle can influence blood sugar levels in women.
Symptoms of High and Low Blood Sugar
Recognizing the symptoms of high (hyperglycemia) and low (hypoglycemia) blood sugar is crucial for taking prompt action.
Symptoms of Hyperglycemia:
- Increased thirst
- Frequent urination
- Blurred vision
- Fatigue
- Headaches
Symptoms of Hypoglycemia:
- Shakiness
- Sweating
- Dizziness
- Confusion
- Hunger
- Irritability
- Rapid heartbeat
If you experience any of these symptoms, it's important to check your blood sugar levels and take appropriate steps to bring them back into the normal range. Consult with your healthcare provider for guidance on managing hyperglycemia and hypoglycemia.

- Engage in Regular Physical Activity: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Maintain a Healthy Weight: Losing even a small amount of weight can improve insulin sensitivity and lower blood sugar levels.
- Manage Stress: Practice stress-reduction techniques like yoga, meditation, or deep breathing exercises.
