Are Your Blood Sugar Levels Normal? (mg/dL and mmol/L Explained)
Understanding your blood sugar levels is crucial for managing your health, especially if you are at risk of or living with diabetes. This article will provide a comprehensive overview of what constitutes normal blood sugar levels, how they are measured (in both mg/dL and mmol/L), and what to do if your levels are outside the normal range. We'll explore different times of day and situations (fasting, after meals) and what those readings ideally should be.
What is Blood Sugar (Glucose)?
Blood sugar, also known as glucose, is the main type of sugar you get from food. Your body breaks down carbohydrates from food into glucose, which is then used for energy. Insulin, a hormone produced by the pancreas, helps glucose get from your blood into your cells for energy. When you have diabetes, your body either doesn't make enough insulin or can't effectively use the insulin it does make, leading to high blood sugar levels.
Why is Monitoring Blood Sugar Important?
Regularly monitoring your blood sugar levels is important for several reasons:

- Early Detection of Diabetes: Identifying abnormal levels early can help prevent long-term complications.
- Diabetes Management: For people with diabetes, monitoring helps them manage their condition, adjust medications, and make informed decisions about diet and exercise.
- Prevention of Complications: Keeping blood sugar levels within a healthy range can reduce the risk of serious health problems like heart disease, kidney disease, nerve damage (neuropathy), and vision loss.
- Lifestyle Adjustments: Understanding how your blood sugar responds to different foods and activities helps you make healthier choices.
Understanding Blood Sugar Measurement Units: mg/dL and mmol/L
Blood sugar levels are commonly measured in 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 is the unit used in Canada, Europe, and many other parts of the world.
It's important to know both units and how to convert between them. To convert from mg/dL to mmol/L, divide the mg/dL value by 18. To convert from mmol/L to mg/dL, multiply the mmol/L value by 18.
Normal Blood Sugar Levels: A Detailed Breakdown
What constitutes a "normal blood sugar" level depends on the timing of the measurement (fasting or after eating) and individual health conditions. The following table provides a general guideline. Consult your doctor for personalized target ranges.
| Category | Fasting Blood Sugar (mg/dL) | Fasting Blood Sugar (mmol/L) | 2-Hour Postprandial (After Meal) (mg/dL) | 2-Hour Postprandial (After Meal) (mmol/L) |
|---|---|---|---|---|
| Normal (No Diabetes) | Less than 100 mg/dL | Less than 5.6 mmol/L | Less than 140 mg/dL | Less than 7.8 mmol/L |
| Prediabetes | 100-125 mg/dL | 5.6-6.9 mmol/L | 140-199 mg/dL | 7.8-11.0 mmol/L |
| Diabetes | 126 mg/dL or higher | 7.0 mmol/L or higher | 200 mg/dL or higher | 11.1 mmol/L or higher |
- Fasting Blood Sugar: This is your blood sugar level after at least eight hours of fasting (no food or drink except water).
- 2-Hour Postprandial: This is your blood sugar level two hours after starting a meal.
It's essential to discuss your blood sugar readings with your doctor. They can interpret the results in the context of your overall health and medical history.
Factors Affecting Blood Sugar Levels
Several factors can influence your blood sugar levels, including:
- Food: The type, amount, and timing of meals and snacks. Carbohydrates have the biggest impact on blood sugar.
- Physical Activity: Exercise can lower blood sugar levels, especially during and immediately after the activity.
- Medications: Some medications, including diabetes medications and steroids, can affect blood sugar.
- Stress: Stress hormones can raise blood sugar levels.
- Illness: Being sick can also increase blood sugar.
- Hormonal Changes: Fluctuations in hormones, such as during menstruation or pregnancy, can impact blood sugar.
- Dehydration: Lack of water can impact blood sugar readings.

Recognizing the symptoms of high and low blood sugar is critical for taking timely action.
Symptoms of High Blood Sugar (Hyperglycemia)
- Increased thirst
- Frequent urination
- Blurred vision
- Fatigue
- Headaches
- Slow-healing sores
- Unexplained weight loss
Symptoms of Low Blood Sugar (Hypoglycemia)
- Shakiness
- Sweating
- Dizziness
- Hunger
- Irritability or confusion
- Rapid heartbeat
- Blurred vision
- Loss of consciousness (in severe cases)
If you experience these symptoms, it's important to check your blood sugar immediately. If you can't test it, treat as hypoglycemia first, as it can have immediate life threatening effects.
What to Do If Your Blood Sugar is High or Low
High Blood Sugar (Hyperglycemia)
- Check your blood sugar: Verify that your levels are indeed elevated.
- Drink water: Stay hydrated to help dilute the glucose in your blood.
- Exercise (if appropriate): If you're able, light exercise can help lower blood sugar.
- Adjust medication (if prescribed): Consult with your doctor on how to adjust your medication in these situations.
- Contact your doctor: If your blood sugar remains high, seek medical advice.
Low Blood Sugar (Hypoglycemia)
- Eat or drink something sugary: Consume 15-20 grams of fast-acting carbohydrates, such as glucose tablets, juice, or regular soda.
- Wait 15 minutes: Recheck your blood sugar after 15 minutes.
- Repeat if needed: If your blood sugar is still low, repeat the process.
- Eat a snack or meal: Once your blood sugar is back to normal, eat a meal or snack to prevent it from dropping again.
- Contact your doctor: Discuss frequent episodes of hypoglycemia with your healthcare provider.
How to Maintain Healthy Blood Sugar Levels
Adopting a healthy lifestyle is key to maintaining healthy blood sugar levels:

Conclusion
Understanding your blood sugar levels is essential for maintaining optimal health. By knowing the normal ranges, recognizing the factors that influence blood sugar, and adopting healthy lifestyle habits, you can effectively manage your blood sugar and reduce the risk of diabetes-related complications. Regularly consulting with your doctor and adhering to their recommendations will help you stay informed and proactive about your health. Remember that the normal blood sugar range can vary based on individual circumstances, so personalized medical advice is always best.
