Are Your Blood Sugar Levels Normal? A Guide to mg/dL and mmol/L
Understanding your blood sugar levels is crucial for maintaining optimal health and preventing complications associated with diabetes. This guide breaks down what normal blood sugar levels should be, how they are measured in both mg/dL and mmol/L, and what to do if your levels are outside the normal range.
Why Blood Sugar Levels Matter
Blood sugar, also known as glucose, is the primary source of energy for your body's cells. It comes from the food you eat. Insulin, a hormone produced by the pancreas, helps glucose from food get into your cells to be used for energy. When you have diabetes, your body either doesn't make enough insulin or can't effectively use the insulin it does produce. This leads to high blood sugar levels, which, over time, can lead to serious health problems, including heart disease, kidney disease, nerve damage, and vision loss. Monitoring and managing your blood sugar is therefore vital.
Understanding the Units: mg/dL vs. mmol/L
Blood sugar levels are typically measured using two different units:
- mg/dL (milligrams per deciliter): This is the standard unit used in the United States and some other countries.
- mmol/L (millimoles per liter): This unit is commonly used in Canada, Europe, and many other parts of the world.
Understanding how to interpret these units is essential for understanding your test results. Use an online converter for accurate calculations.
Normal Blood Sugar Levels: Target Ranges
Normal blood sugar levels can vary depending on the time of day and when you last ate. The following table provides general guidelines for people without diabetes.
| Measurement | Normal Range (mg/dL) | Normal Range (mmol/L) |
|---|---|---|
| Fasting Blood Sugar (After at least 8 hours of fasting) | Less than 100 mg/dL | Less than 5.6 mmol/L |
| 2 Hours After Eating (Postprandial) | Less than 140 mg/dL | Less than 7.8 mmol/L |
Note: These are general guidelines. Your doctor may recommend different target ranges based on your individual health needs.
Blood Sugar Levels and Diabetes
For individuals with diabetes, target blood sugar ranges are typically different to effectively manage their condition. These targets are aimed at preventing both hyperglycemia (high blood sugar) and hypoglycemia (low blood sugar).
Target Blood Sugar Levels for People with Diabetes
| Measurement | Target Range (mg/dL) | Target Range (mmol/L) |
|---|---|---|
| Fasting Blood Sugar (Before meals) | 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 |
Again, it's vital to work with your healthcare provider to establish personalized blood sugar targets.

What If Your Blood Sugar Levels Are Not Normal?
If your blood sugar levels are consistently outside the normal range, it's important to consult your doctor. Here are possible scenarios and actions to take:
- High Blood Sugar (Hyperglycemia): If your blood sugar is consistently high, it could indicate that your diabetes management plan needs adjustment. Symptoms may include increased thirst, frequent urination, blurred vision, and fatigue. You will want to seek medical advice if your readings are frequently above target or you experience severe symptoms. Long-term, uncontrolled blood sugar levels can lead to serious health problems.
- Low Blood Sugar (Hypoglycemia): If your blood sugar drops too low, it can cause symptoms such as shakiness, sweating, confusion, and dizziness. If you experience these symptoms, immediately consume a fast-acting carbohydrate source (e.g., glucose tablets, juice, regular soda) and then follow up with a more substantial snack. Work with your healthcare provider to understand why your blood sugar is dropping and adjust your treatment plan accordingly.
Monitoring Your Blood Sugar
Regular blood sugar monitoring is crucial for managing diabetes and maintaining optimal health. There are several ways to monitor your blood sugar:
- Home Blood Glucose Meter (Glucometer): This is the most common method, involving pricking your finger to obtain a small blood sample. These are available at most pharmacies.
- Continuous Glucose Monitoring (CGM): A CGM device continuously tracks your blood sugar levels throughout the day and night via a small sensor inserted under your skin. This offers a more comprehensive view of your glucose trends. CGMs are also available through a prescription from your doctor.
- A1C Test: This blood test provides an average of your blood sugar levels over the past 2-3 months. It is typically performed in a doctor's office. The A1C test is used to monitor the effectiveness of your diabetes treatment plan.

- Eat a Balanced Diet: Focus on consuming a variety of fruits, vegetables, whole grains, and lean proteins. Limit your intake of processed foods, sugary drinks, and saturated and trans fats.
- Engage in Regular Physical Activity: Aim for at least 30 minutes of moderate-intensity exercise most days of the week. Physical activity helps improve insulin sensitivity and lower blood sugar levels.
- Manage Stress: Stress can affect blood sugar levels. Find healthy ways to manage stress, such as yoga, meditation, or spending time in nature.
- Stay Hydrated: Drink plenty of water throughout the day to help your kidneys flush out excess glucose.
- Get Enough Sleep: Poor sleep can disrupt hormones that regulate blood sugar levels. Aim for 7-8 hours of quality sleep per night.
Conclusion
Understanding and monitoring your blood sugar levels is vital for maintaining overall health and preventing complications, especially if you have diabetes. By knowing the normal ranges in both mg/dL and mmol/L, taking proactive steps to manage your lifestyle, and consulting with your healthcare provider, you can effectively manage your blood sugar and live a healthier life. Regular check-ups and adherence to your healthcare provider's recommendations are essential.
