Blood Sugar Levels Explained: Understanding mg/dL, mmol/L, and Your Results
Understanding blood sugar levels is crucial for managing your health, especially if you have diabetes or are at risk. This comprehensive guide will break down what blood sugar levels mean, the difference between mg/dL and mmol/L, and how to interpret your results. We'll cover everything from normal ranges to what to do if your blood sugar is too high or too low. Let’s dive in!
Why Monitoring Blood Sugar Levels Matters
Monitoring your blood sugar allows you to understand how food, exercise, medication, and stress affect your levels. This knowledge empowers you to make informed decisions about your diet and lifestyle, helping you keep your blood glucose levels within a healthy range. For people with diabetes, regular monitoring is essential for preventing complications such as heart disease, kidney damage, and nerve damage.
Understanding the Units: mg/dL vs. mmol/L
Blood sugar levels are typically measured in one of two 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 is the standard unit used in Canada, Europe, and many other parts of the world.
It’s important to know which unit your test results are reported in to accurately interpret them.
Converting Between mg/dL and mmol/L
You can easily convert between these units using the following formulas:
- mg/dL to mmol/L: Divide mg/dL by 18.
- mmol/L to mg/dL: Multiply mmol/L by 18.
For example, a blood sugar level of 100 mg/dL is equivalent to approximately 5.5 mmol/L (100 / 18 = 5.55).

Understanding what's considered a normal blood sugar range is crucial. These values typically vary depending on when the measurement is taken.
| Category | mg/dL | mmol/L |
|---|---|---|
| Fasting (before breakfast) for Non-Diabetic | 70-99 | 3.9-5.5 |
| Fasting (before breakfast) for Diabetic | 80-130 | 4.4-7.2 |
| 2 hours after meal for Non-Diabetic | Less than 140 | Less than 7.8 |
| 2 hours after meal for Diabetic | Less than 180 | Less than 10.0 |
Note: These ranges are general guidelines. Your target blood sugar levels may vary based on your individual health circumstances. Consult your healthcare provider for personalized advice.
Understanding Your Results: High and Low Blood Sugar
Hyperglycemia (High Blood Sugar)
Hyperglycemia, or high blood sugar, occurs when there's too much glucose in your blood. This can happen if you eat too many carbohydrates, don’t take enough insulin (if you have diabetes), or are experiencing stress or illness.
Symptoms of Hyperglycemia:
- Increased thirst
- Frequent urination
- Blurred vision
- Fatigue
- Headaches
What to Do:
- Check your blood sugar.
- If you take insulin or other diabetes medications, follow your healthcare provider's instructions.
- Drink plenty of water to stay hydrated.
- Avoid sugary foods and drinks.
- Contact your doctor if your blood sugar remains high.
Hypoglycemia (Low Blood Sugar)

Hypoglycemia, or low blood sugar, happens when your blood glucose levels drop too low. This can be caused by skipping meals, taking too much insulin (if you have diabetes), or engaging in strenuous exercise.
Symptoms of Hypoglycemia:
- Shakiness
- Sweating
- Dizziness
- Confusion
- Irritability
- Hunger
What to Do:
- Check your blood sugar immediately.
- If your blood sugar is below 70 mg/dL (3.9 mmol/L), consume 15-20 grams of fast-acting carbohydrates (e.g., glucose tablets, fruit juice, hard candy).
- Wait 15 minutes and recheck your blood sugar.
- Repeat steps 2 and 3 until your blood sugar is above 70 mg/dL (3.9 mmol/L).
- Once your blood sugar is stable, eat a meal or snack to prevent it from dropping again.
- If you have frequent episodes of hypoglycemia, consult your doctor.
Factors Affecting Blood Sugar Levels
Numerous factors can influence your blood sugar levels. Understanding these can help you manage your diabetes or prevent future problems:
- Diet: The types and amount of food you consume. Carbohydrates have the most significant impact on blood sugar.
- Exercise: Physical activity can lower blood sugar levels as your body uses glucose for energy.
- Medications: Certain medications, like insulin and oral diabetes drugs, directly affect blood glucose levels.
- Stress: Stress hormones can raise blood sugar.
- Illness: Illness can also lead to fluctuations in blood sugar levels.
- Sleep: Lack of sleep can affect insulin sensitivity and increase blood sugar.
- Menstrual cycle: Hormonal changes during menstruation can impact blood sugar levels in women.
Tips for Maintaining Healthy Blood Sugar Levels
Adopting a healthy lifestyle is key to maintaining stable blood sugar levels:
- Eat a Balanced Diet: Focus on whole grains, lean proteins, healthy fats, and plenty of fruits and vegetables.
- Monitor Carbohydrate Intake: Be mindful of the amount and type of carbohydrates you consume. Choose complex carbohydrates over simple sugars.
- Exercise Regularly: Aim for at least 150 minutes of moderate-intensity exercise per week.
- Monitor Your Blood Sugar: Check your blood sugar regularly, especially if you have diabetes.
- Manage Stress: Practice relaxation techniques such as deep breathing, meditation, or yoga.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep each night.
- Stay Hydrated: Drink plenty of water to help your body function properly.
The Role of A1C in Blood Sugar Management
The A1C test provides an average of your blood sugar levels over the past 2-3 months. It's a valuable tool for assessing long-term blood glucose control, particularly for people with diabetes. The A1C goal for many adults with diabetes is generally below 7%. However, individual goals may vary.
| A1C (%) | Estimated Average Glucose (eAG) mg/dL | Estimated Average Glucose (eAG) mmol/L |
|---|---|---|
| 6 | 126 | 7.0 |
| 7 | 154 | 8.6 |
| 8 | 183 | 10.2 |
| 9 | 212 | 11.8 |
Continuous Glucose Monitoring (CGM)
Continuous glucose monitoring (CGM) systems provide real-time blood sugar readings throughout the day and night. These devices can help you identify trends and patterns in your glucose levels, allowing you to make more informed decisions about your diet, exercise, and medication. CGMs are particularly useful for individuals with type 1 diabetes or those who experience frequent fluctuations in their blood sugar.

When to Seek Medical Advice
While managing blood sugar levels at home is essential, it's crucial to know when to seek professional medical advice:
- Frequent episodes of hyperglycemia or hypoglycemia: If you're consistently experiencing high or low blood sugar levels, despite your best efforts, consult your doctor.
- Unexplained weight loss or gain: Significant changes in weight can indicate underlying issues with blood sugar control.
- Symptoms of diabetes complications: If you experience symptoms such as blurred vision, numbness or tingling in your hands or feet, or frequent infections, seek medical attention.
- Difficulty managing blood sugar during illness: Illness can make it harder to control blood glucose levels. Contact your doctor for guidance.
- Changes in medication: Always consult your healthcare provider before making any changes to your diabetes medications.
In Conclusion: Taking Control of Your Blood Sugar
Understanding blood sugar levels in mg/dL and mmol/L is a fundamental step towards managing your health. By knowing what's considered normal, recognizing the signs of high and low blood sugar, and adopting a healthy lifestyle, you can take proactive steps to maintain stable glucose levels and prevent complications. Remember to consult your healthcare provider for personalized advice and guidance.
