Your Complete Guide to Reading a Blood Sugar Levels Chart (mg/dL & mmol/L)
Understanding a blood sugar levels chart is crucial for managing diabetes and maintaining overall health. This comprehensive guide will walk you through how to interpret the numbers, differentiate between mg/dL and mmol/L, and what actions to take based on your readings. We’ll cover normal ranges, what to do if your blood sugar is high or low, and how to use this information effectively.
Why is Understanding Blood Sugar Levels Important?
Blood sugar levels, also known as blood glucose levels, are a critical indicator of how well your body is processing sugar. Maintaining healthy blood sugar levels is vital because:
- Diabetes Management: Helps individuals with diabetes monitor their condition and adjust treatment plans.
- Preventing Complications: Consistently high blood sugar can lead to severe health problems like heart disease, kidney disease, and nerve damage.
- General Health: Even for those without diabetes, understanding blood sugar can aid in making informed dietary and lifestyle choices to prevent future health issues.
What are the Standard Units for Measuring Blood Sugar? (mg/dL vs. mmol/L)
Blood sugar levels are typically measured in two units:
- mg/dL (milligrams per deciliter): This unit is predominantly used in the United States.
- mmol/L (millimoles per liter): This unit is commonly used in Canada, Europe, and other parts of the world.
It's important to know the conversion factor between these units:
- To convert mg/dL to mmol/L, divide by 18 (approximately).
- To convert mmol/L to mg/dL, multiply by 18 (approximately).
Knowing these conversions is vital if you are moving between countries or encountering different lab reports.

Normal Blood Sugar Levels Chart
The following blood sugar levels chart provides general guidelines for normal ranges. However, individual targets may vary based on age, overall health, and specific conditions. Always consult with your healthcare provider for personalized recommendations.
| Category | mg/dL (Fasting) | mmol/L (Fasting) | mg/dL (2 hours after eating) | mmol/L (2 hours after eating) |
|---|---|---|---|---|
| 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 to 125 mg/dL | 5.6 to 6.9 mmol/L | 140 to 199 mg/dL | 7.8 to 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 |
Note: These ranges are general guidelines. Consult your doctor for personalized targets.

Understanding Fasting Blood Sugar
Fasting blood sugar is measured after an overnight fast (typically at least 8 hours). This reading gives a baseline assessment of how well your body regulates blood sugar without the influence of food intake. A normal fasting blood sugar is typically below 100 mg/dL (5.6 mmol/L).
Understanding Postprandial Blood Sugar (2 Hours After Eating)
Postprandial blood sugar refers to the blood sugar levels measured two hours after eating a meal. This measurement indicates how effectively your body is processing glucose from food. A normal reading two hours after eating should be less than 140 mg/dL (7.8 mmol/L).
What To Do If Your Blood Sugar Is High (Hyperglycemia)
If your blood sugar levels are consistently high, it’s important to take action. Here's a step-by-step guide:
- Check Your Blood Sugar: Confirm the high reading with another test.
- Drink Water: Staying hydrated helps to dilute blood sugar.
- Exercise: Engage in light physical activity like walking to help use up excess glucose. However, if you have diabetes and your blood sugar is very high (e.g., above 250 mg/dL or 13.9 mmol/L), check with your doctor before exercising.
- Adjust Medication (If Applicable): If you have diabetes, follow your healthcare provider's instructions regarding medication adjustments.
- Monitor Closely: Continue to check your blood sugar regularly to ensure it returns to a safe range.
- Contact Your Doctor: If high blood sugar persists despite these measures, seek medical advice.
What To Do If Your Blood Sugar Is Low (Hypoglycemia)
Low blood sugar, or hypoglycemia, requires immediate attention. Here’s what you should do:
- Check Your Blood Sugar: Confirm the low reading (typically below 70 mg/dL or 3.9 mmol/L).
- Consume Quick-Acting Carbohydrates: Eat or drink something containing 15-20 grams of fast-acting carbs, such as:
- Glucose tablets
- Fruit juice (4 ounces)
- Regular (non-diet) soda (4 ounces)
- Hard candies
- Wait 15 Minutes: Recheck your blood sugar after 15 minutes.
- Repeat if Necessary: If your blood sugar is still low, repeat steps 2 and 3.
- Eat a Meal or Snack: Once your blood sugar returns to a normal range, eat a meal or snack containing both carbohydrates and protein to stabilize it.
- Seek Medical Attention: If you experience severe symptoms like confusion, seizures, or loss of consciousness, seek immediate medical assistance.
Factors Affecting Blood Sugar Levels
Various factors can influence blood sugar levels, including:
- Diet: The type and amount of food you consume, particularly carbohydrates.
- Physical Activity: Exercise can lower blood sugar, while inactivity can raise it.
- Stress: Stress hormones can increase blood sugar.
- Illness: Infections and other illnesses can affect blood sugar levels.
- Medications: Certain medications, such as steroids, can increase blood sugar.
- Hydration: Dehydration can affect blood sugar readings.
- Sleep: Lack of sleep or irregular sleep patterns can affect blood sugar.
How To Use A Blood Glucose Meter Correctly
Using a blood glucose meter correctly is essential for accurate readings. Follow these steps:
- Wash Your Hands: Thoroughly wash your hands with soap and warm water.
- Prepare Your Lancing Device: Insert a new lancet into the lancing device.
- Choose a Prick Site: Select a fingertip (usually the side) and clean it with an alcohol swab. Allow it to dry completely.
- Prick Your Finger: Use the lancing device to prick your fingertip.
- Apply Blood to the Test Strip: Gently squeeze your finger to obtain a small drop of blood. Touch the test strip to the blood droplet, allowing it to be absorbed.
- Read the Results: The meter will display your blood sugar level.
- Record the Reading: Log your blood sugar levels along with the time, date, and any relevant notes (e.g., after a meal, before exercise).
Tips for Maintaining Healthy Blood Sugar Levels
Here are some tips for keeping your blood sugar within a healthy range:
- Follow a Balanced Diet: Emphasize whole grains, fruits, vegetables, lean proteins, and healthy fats. Limit processed foods, sugary drinks, and excessive carbohydrates.
- Exercise Regularly: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Monitor Your Blood Sugar Regularly: Check your blood sugar as directed by your healthcare provider.
- Stay Hydrated: Drink plenty of water throughout the day.
- Manage Stress: Practice stress-reduction techniques such as meditation, yoga, or deep breathing exercises.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep each night.
- Take Medications as Prescribed: If you have diabetes, follow your healthcare provider's instructions regarding medication.
- Regular Check-ups: Schedule regular visits with your healthcare provider to monitor your overall health and blood sugar control.
The Importance of HbA1c Testing
While self-monitoring of blood sugar levels provides immediate feedback, the HbA1c test offers a longer-term view. HbA1c (glycated hemoglobin) reflects your average blood sugar levels over the past 2-3 months. It is typically measured as a percentage.
| Category | HbA1c (%) |
|---|---|
| Normal (No Diabetes) | Less than 5.7% |
| Prediabetes | 5.7% to 6.4% |
| Diabetes | 6.5% or higher |

Conclusion
Understanding and effectively using a blood sugar levels chart is an essential skill for anyone managing diabetes or simply wanting to improve their overall health. By knowing the normal ranges, understanding the factors that influence blood sugar, and taking appropriate actions when levels are too high or too low, you can proactively manage your health and reduce the risk of long-term complications. Always work closely with your healthcare provider to develop a personalized plan that meets your specific needs and goals. Regular monitoring and lifestyle adjustments can significantly improve your quality of life and promote long-term well-being.
