The Ultimate Guide to Your Blood Sugar Levels Chart (mg/dL & mmol/L)
Understanding your blood sugar levels is crucial for managing diabetes or simply staying healthy. This comprehensive guide breaks down everything you need to know about interpreting your blood sugar levels chart, whether it’s in mg/dL (milligrams per deciliter) or mmol/L (millimoles per liter). We'll cover normal ranges, what high and low readings mean, factors that can affect your blood sugar, and tips for keeping your blood sugar levels stable.

Regular blood sugar monitoring provides vital insights into how your body processes glucose. This information helps you and your healthcare provider:
- Detect high or low blood sugar levels.
- Understand how diet, exercise, and medication affect your blood sugar.
- Make informed decisions about your treatment plan.
- Prevent long-term complications associated with diabetes.
Blood Sugar Levels Chart: Understanding the Numbers
The following charts detail acceptable blood sugar levels for people with and without diabetes. Keep in mind that individual targets may vary, so always consult your doctor.
Fasting Blood Sugar Levels
Fasting blood sugar is measured after at least eight hours of not eating.
| Category | mg/dL | mmol/L |
|---|---|---|
| Normal | Less than 100 | Less than 5.6 |
| Prediabetes | 100 to 125 | 5.6 to 6.9 |
| Diabetes | 126 or higher | 7.0 or higher |
Blood Sugar Levels 2 Hours After Eating (Postprandial)
This measures your blood sugar two hours after the start of a meal.
| Category | mg/dL | mmol/L |
|---|---|---|
| Normal | Less than 140 | Less than 7.8 |
| Diabetes | 180 or higher | 10.0 or higher |
HbA1c Levels
HbA1c measures your average blood sugar levels over the past 2-3 months.
| Category | HbA1c (%) |
|---|---|
| Normal | Less than 5.7% |
| Prediabetes | 5.7% to 6.4% |
| Diabetes | 6.5% or higher |
Important Note: Always discuss your target blood sugar ranges with your doctor as these can vary depending on your age, health conditions, and treatment plan.

Hyperglycemia occurs when your blood sugar levels are too high. Symptoms may include:
- Frequent urination
- Increased thirst
- Blurred vision
- Fatigue
- Headache

If left untreated, hyperglycemia can lead to serious complications like diabetic ketoacidosis (DKA) or hyperglycemic hyperosmolar state (HHS).
What Happens When Blood Sugar Is Too Low (Hypoglycemia)?
Hypoglycemia happens when your blood sugar levels drop too low. Symptoms may include:
- Shakiness
- Sweating
- Dizziness
- Confusion
- Hunger
- Irritability
Severe hypoglycemia can lead to seizures, loss of consciousness, and even death if not treated promptly. It's crucial to have a quick-acting source of glucose readily available if you are at risk of hypoglycemia.
Factors That Can Affect Your Blood Sugar Levels
Many factors can influence your blood sugar levels, including:
- Diet: Carbohydrate intake significantly impacts blood sugar.
- Exercise: Physical activity can lower blood sugar.
- Medications: Certain medications, like insulin and oral diabetes drugs, directly affect blood sugar. Other medications, such as steroids, can raise it.
- Stress: Stress hormones can increase blood sugar.
- Illness: Infections and illnesses can impact blood sugar regulation.
- Hormonal Changes: Menstrual cycles and menopause can influence blood sugar levels in women.
- Dehydration: Dehydration can concentrate blood sugar, leading to higher readings.
- Alcohol Consumption: Alcohol can initially raise blood sugar, but then cause it to drop.
- Sleep: Lack of sleep can affect blood sugar control.
Tips for Keeping Your Blood Sugar Levels Stable
Maintaining stable blood sugar levels is essential for overall health. Here are some strategies:
- Follow a Healthy Diet: Focus on whole, unprocessed foods, including fruits, vegetables, lean proteins, and whole grains. Limit sugary drinks, processed foods, and unhealthy fats. Carbohydrate counting can be particularly helpful.
- Engage in Regular Exercise: Aim for at least 150 minutes of moderate-intensity aerobic exercise per week. Include strength training exercises as well.
- Monitor Your Blood Sugar Regularly: Use a blood glucose meter to check your blood sugar levels as recommended by your doctor. Consider using a continuous glucose monitor (CGM) for more comprehensive tracking.
- Take Medications as Prescribed: Adhere to your doctor's instructions regarding medications for diabetes.
- Manage Stress: Practice stress-reducing techniques such as meditation, yoga, or deep breathing exercises.
- Stay Hydrated: Drink plenty of water throughout the day.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep per night.
- Work Closely with Your Healthcare Team: Schedule regular checkups with your doctor and diabetes educator to review your treatment plan and make adjustments as needed.
Converting Between mg/dL and mmol/L
Sometimes, you might need to convert between mg/dL and mmol/L. Here's how:
- 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.
Advanced Monitoring with Continuous Glucose Monitors (CGMs)
Continuous glucose monitors (CGMs) are devices that track blood sugar levels in real-time throughout the day and night. They provide valuable data to help you understand how your blood sugar responds to food, exercise, and other factors. CGMs can also alert you to high or low blood sugar levels, allowing you to take proactive steps to manage your diabetes.
Conclusion
Understanding your blood sugar levels chart is a critical step in managing your health, especially if you have diabetes or prediabetes. By monitoring your blood sugar, following a healthy lifestyle, and working closely with your healthcare team, you can maintain stable blood sugar levels and reduce your risk of complications. Remember to consult your doctor to determine the target blood sugar ranges that are right for you. Use this guide as a valuable tool to empower yourself with knowledge and take control of your blood sugar management.
