Blood Glucose Levels 101: Understanding Mg/dL, mmol/L, and Your Health
Understanding blood glucose levels is crucial for maintaining good health, especially for individuals with diabetes or those at risk. This article will break down everything you need to know, including what blood glucose levels mean, the difference between mg/dL and mmol/L, and how to maintain healthy levels. Let's dive in!
What is Blood Glucose?
Blood glucose, also known as blood sugar, is the main sugar found in your blood. It comes from the food you eat and is your body's primary source of energy. Your blood carries glucose to all of your body's cells to use for energy. The hormone insulin, produced by the pancreas, helps glucose get into your cells.
Why are Blood Glucose Levels Important?
Maintaining stable blood glucose levels is vital for optimal health. Consistently high levels (hyperglycemia) can lead to serious health complications like:
- Type 2 diabetes: Characterized by insulin resistance and high blood sugar.
- Heart disease: High glucose can damage blood vessels and increase the risk of cardiovascular problems.
- Kidney disease: High glucose can damage the kidneys, potentially leading to kidney failure.
- Nerve damage (neuropathy): High glucose can damage nerves, causing pain, numbness, and other issues.
- Eye damage (retinopathy): High glucose can damage blood vessels in the retina, potentially leading to blindness.
Conversely, consistently low levels (hypoglycemia) can lead to:
- Confusion and dizziness: The brain relies on glucose for energy.
- Seizures: Severe hypoglycemia can trigger seizures.
- Loss of consciousness: Prolonged low glucose can cause loss of consciousness.
Understanding the Units: Mg/dL vs. mmol/L
Blood glucose levels are typically measured in one of two units:
- Mg/dL (milligrams per deciliter): This is the standard measurement used in the United States and some other countries.
- mmol/L (millimoles per liter): This is the standard measurement used in most of the world, including Canada, Europe, and Australia.
It's important to know both, as different resources might use different units. Fortunately, converting between the two is simple:
- To convert mg/dL to mmol/L: Divide the mg/dL value by 18.
- To convert mmol/L to mg/dL: Multiply the mmol/L value by 18.
For example, 100 mg/dL is approximately equal to 5.5 mmol/L (100 / 18 = 5.55).

Target blood glucose levels vary depending on individual factors, such as age, overall health, and the presence of diabetes. However, general guidelines exist for healthy individuals and those with diabetes.
Here’s a general guide, although you should always consult with your healthcare provider for personalized advice:
| Category | Fasting Blood Sugar (mg/dL) | Fasting Blood Sugar (mmol/L) | 2 Hours After Eating (mg/dL) | 2 Hours After Eating (mmol/L) |
|---|---|---|---|---|
| Healthy Individuals | 70-99 | 3.9-5.5 | Less than 140 | Less than 7.8 |
| Individuals with Diabetes | 80-130 | 4.4-7.2 | Less than 180 | Less than 10.0 |
Important Considerations:
- Fasting Blood Sugar: Measured after at least 8 hours of fasting (no food or drink).
- 2 Hours After Eating: Measured 2 hours after the start of a meal.
- Individual Goals: Consult your doctor for your specific target range. These numbers are general guidelines. Individual needs may vary based on factors like age, pregnancy, and other medical conditions.
How to Monitor Your Blood Glucose
There are several ways to monitor your blood glucose levels:
- Finger-prick Test: This involves using a lancet to prick your finger and placing a drop of blood on a test strip, which is then inserted into a blood glucose meter. This is the most common method for home monitoring.
- Continuous Glucose Monitoring (CGM): A CGM device uses a small sensor inserted under the skin to continuously monitor glucose levels. The sensor sends readings to a receiver or smartphone app. CGMs offer valuable insights into glucose trends and can alert you to high or low glucose levels.
- A1C Test: This blood test provides an average of your blood glucose levels over the past 2-3 months. It's typically performed by a healthcare professional. A1C is expressed as a percentage; the higher the percentage, the higher your average blood glucose level.
Tips for Maintaining Healthy Blood Glucose Levels
Maintaining healthy blood glucose levels involves lifestyle adjustments:
- Balanced Diet: Focus on a diet rich in fruits, vegetables, whole grains, and lean protein. Limit processed foods, sugary drinks, and excessive carbohydrates.
- Regular Exercise: Physical activity helps improve insulin sensitivity and lowers blood glucose levels. Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Medication Adherence: If you have diabetes, follow your doctor's instructions regarding medication and insulin.
- Weight Management: Maintaining a healthy weight can significantly improve insulin sensitivity and blood glucose control.
- Stress Management: Stress can impact blood glucose levels. Practice relaxation techniques like yoga, meditation, or deep breathing exercises.
- Regular Monitoring: Monitor your blood glucose levels regularly, as recommended by your healthcare provider, to track your progress and make necessary adjustments to your treatment plan.
When to See a Doctor
Consult your doctor if you experience any of the following:
- Frequent high or low blood glucose readings, despite following your treatment plan.
- Symptoms of hyperglycemia (increased thirst, frequent urination, blurred vision, fatigue).
- Symptoms of hypoglycemia (shakiness, sweating, dizziness, confusion).
- Changes in your vision or other health problems.
