Are Your Blood Sugar Levels Normal? Understanding mg/dL and mmol/L
Understanding your blood sugar levels is crucial for maintaining good health, especially if you're at risk for or have been diagnosed with diabetes. This article provides a comprehensive overview of what normal blood sugar levels are, how they are measured in both mg/dL and mmol/L, and what actions you should take if your levels fall outside the normal range. Let's dive in!
What is Blood Sugar and Why is it Important?
Blood sugar, also known as glucose, is the main type of sugar found in your blood. It comes from the food you eat and is your body's primary source of energy. Your pancreas produces insulin, a hormone that helps glucose from food get into your cells to be used for energy. When you have diabetes, either your body doesn’t make enough insulin or can’t effectively use the insulin it produces, leading to high blood sugar levels.
Maintaining normal blood sugar levels is essential because chronic hyperglycemia (high blood sugar) can lead to serious health complications, including:
- Heart disease
- Kidney disease
- Nerve damage (neuropathy)
- Eye damage (retinopathy)
Understanding the Units: mg/dL vs. mmol/L
Blood sugar levels are typically measured using two different units: milligrams per deciliter (mg/dL) and millimoles per liter (mmol/L). Both units are commonly used, but the preferred unit can vary by region and laboratory. It’s important to know how to interpret blood sugar readings in both units.
-
mg/dL (Milligrams per deciliter): This unit measures the weight of glucose (in milligrams) in a specific volume of blood (deciliter). It is predominantly used in the United States.

-
mmol/L (Millimoles per liter): This unit measures the concentration of glucose (in millimoles) in a specific volume of blood (liter). It is more commonly used in many other parts of the world, including Canada and Europe.
Normal Blood Sugar Levels: A Comprehensive Guide
What constitutes a normal blood sugar level depends on several factors, including when the measurement is taken (fasting, before meals, after meals), your age, and whether you have diabetes. Here's a detailed breakdown:

Fasting Blood Sugar (FBS)
Fasting blood sugar is measured after an overnight fast (at least 8 hours).
| Category | mg/dL | mmol/L | Interpretation |
|---|---|---|---|
| Normal | Less than 100 mg/dL | Less than 5.6 mmol/L | Healthy **blood sugar** level. |
| Prediabetes | 100 to 125 mg/dL | 5.6 to 6.9 mmol/L | Increased risk of developing diabetes. |
| Diabetes | 126 mg/dL or higher | 7.0 mmol/L or higher | Indicates diabetes; further testing needed. |
Blood Sugar Before Meals (For People with Diabetes)
| Category | mg/dL | mmol/L | Goal |
|---|---|---|---|
| Target Range | 80-130 mg/dL | 4.4-7.2 mmol/L | Optimal **blood sugar** control before eating. |
Blood Sugar 1-2 Hours After Meals (For People with Diabetes)
| Category | mg/dL | mmol/L | Goal |
|---|---|---|---|
| Target Range | Less than 180 mg/dL | Less than 10.0 mmol/L | Helps prevent post-meal spikes. |
Blood Sugar Levels for Pregnant Women with Gestational Diabetes
Gestational diabetes requires tighter control of blood sugar to ensure the health of both the mother and the baby.
| Category | mg/dL | mmol/L | Goal |
|---|---|---|---|
| Fasting | Less than 95 mg/dL | Less than 5.3 mmol/L | Keeps baseline **blood sugar** optimal. |
| 1 Hour After Meals | Less than 140 mg/dL | Less than 7.8 mmol/L | Minimizes spikes after eating. |
| 2 Hours After Meals | Less than 120 mg/dL | Less than 6.7 mmol/L | Further control of post-meal **blood sugar**. |
HbA1c: Average Blood Sugar Over Time
The HbA1c test measures your average blood sugar level over the past 2-3 months. It's a valuable tool for managing diabetes and assessing the effectiveness of treatment.
| Category | HbA1c | Interpretation |
|---|---|---|
| Normal | Less than 5.7% | Healthy average **blood sugar**. |
| Prediabetes | 5.7% to 6.4% | Increased risk of developing diabetes. |
| Diabetes | 6.5% or higher | Indicates diabetes; needs management. |
What To Do If Your Blood Sugar Levels Are Abnormal
If your blood sugar levels consistently fall outside the normal range, it’s important to consult with your healthcare provider. Here are general steps you might consider:
- Consult a Doctor: This is the most important step. They can provide personalized recommendations based on your health history.
- Lifestyle Changes: Diet and exercise play a crucial role. A balanced diet low in processed sugars and regular physical activity can help regulate blood sugar.
- Medication: Your doctor might prescribe medication to help control blood sugar levels, especially if you have diabetes.
- Regular Monitoring: Regularly check your blood sugar levels as directed by your healthcare provider. Keep a log of your readings to identify patterns and potential triggers.
- Dietary Changes: Reduce intake of sugary drinks, processed foods, and refined carbohydrates. Increase fiber intake through fruits, vegetables, and whole grains.
Tips for Maintaining Healthy Blood Sugar Levels
Here are some additional tips to help you maintain healthy blood sugar levels:
- Eat a Balanced Diet: Focus on whole, unprocessed foods, including plenty of fruits, vegetables, lean protein, and whole grains.
- Exercise Regularly: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Stay Hydrated: Drink plenty of water throughout the day.
- Manage Stress: High stress levels can affect blood sugar. Practice relaxation techniques like meditation or yoga.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep each night.
- Limit Alcohol Intake: Alcohol can affect blood sugar levels, especially if you have diabetes. Consume alcohol in moderation and always with food.
Converting Between mg/dL and mmol/L
To convert blood sugar levels from mg/dL to mmol/L, you can use the following formula:

- mmol/L = mg/dL ÷ 18
To convert from mmol/L to mg/dL:
- mg/dL = mmol/L × 18
For example:
- If your blood sugar level is 126 mg/dL, then in mmol/L it would be 126 ÷ 18 = 7.0 mmol/L.
- If your blood sugar level is 5.0 mmol/L, then in mg/dL it would be 5.0 x 18 = 90 mg/dL.
Conclusion
Understanding your blood sugar levels and what they mean in both mg/dL and mmol/L is essential for proactive health management. Regular monitoring, a healthy lifestyle, and consistent communication with your healthcare provider can help you keep your blood sugar within a healthy range, reducing your risk of diabetes-related complications. If you have concerns about your blood sugar, don't hesitate to seek professional medical advice.
