Your Complete Guide to Blood Sugar Levels: Chart Included (mg/dL & mmol/L)
Understanding blood sugar levels is crucial for maintaining overall health, especially if you're managing diabetes or at risk of developing it. This comprehensive guide will explain what blood sugar is, why it's important, the different types of blood sugar tests, and provide a handy blood sugar chart in both mg/dL and mmol/L to help you interpret your results.
What is Blood Sugar and Why Does It Matter?
Blood sugar, also known as glucose, is the main sugar found in your blood. It comes from the food you eat and is your body's primary source of energy. The level of sugar in your blood is tightly controlled by a hormone called insulin, produced by the pancreas.
Why is maintaining healthy blood sugar levels important? When blood sugar levels are consistently too high (hyperglycemia) or too low (hypoglycemia), it can lead to serious health problems.
- Hyperglycemia (High Blood Sugar): Over time, high blood sugar can damage your blood vessels, nerves, and organs, increasing the risk of heart disease, stroke, kidney disease, vision problems (including blindness), and nerve damage (neuropathy).
- Hypoglycemia (Low Blood Sugar): Low blood sugar can cause symptoms such as shakiness, sweating, dizziness, confusion, and even loss of consciousness. Severe hypoglycemia can be life-threatening.
Therefore, regularly monitoring your blood sugar and maintaining levels within the target range recommended by your doctor is essential for preventing these complications and maintaining optimal health.
Types of Blood Sugar Tests
Several types of blood sugar tests are used to monitor glucose levels and diagnose diabetes. The most common ones include:
- Fasting Blood Sugar (FBS) Test: This test measures your blood sugar after an overnight fast (at least 8 hours). It is often used to screen for diabetes.
- Random Blood Sugar (RBS) Test: This test measures your blood sugar at any time of day, regardless of when you last ate. It's useful for diagnosing diabetes when symptoms are present.
- Oral Glucose Tolerance Test (OGTT): This test measures your blood sugar before and two hours after you drink a special sugary drink. It is commonly used to diagnose gestational diabetes (diabetes during pregnancy).
- A1C Test (Glycated Hemoglobin Test): This test provides an average of your blood sugar levels over the past 2-3 months. It does not require fasting and is a useful tool for managing diabetes.
Your doctor will determine which test is appropriate for you based on your individual health history and risk factors. Understanding the purpose of each test and how the results are interpreted is crucial for managing your health effectively.

Blood sugar levels are typically measured in milligrams per deciliter (mg/dL) in the United States and some other countries. In most other parts of the world, they are measured in millimoles per liter (mmol/L). The following blood sugar chart provides reference ranges in both units for various types of blood sugar tests.
| Test | Normal Range (mg/dL) | Normal Range (mmol/L) | Prediabetes (mg/dL) | Prediabetes (mmol/L) | Diabetes (mg/dL) | Diabetes (mmol/L) |
|---|---|---|---|---|---|---|
| Fasting Blood Sugar (FBS) | 70-99 | 3.9-5.5 | 100-125 | 5.6-6.9 | 126 or higher | 7.0 or higher |
| Random Blood Sugar (RBS) | N/A (Levels vary throughout the day) | N/A (Levels vary throughout the day) | N/A | N/A | 200 or higher | 11.1 or higher |
| Oral Glucose Tolerance Test (OGTT) - 2 hours after | Less than 140 | Less than 7.8 | 140-199 | 7.8-11.0 | 200 or higher | 11.1 or higher |
| A1C Test | Less than 5.7% | N/A | 5.7-6.4% | N/A | 6.5% or higher | N/A |
Important Considerations:
- These ranges are general guidelines and may vary slightly depending on the lab and the individual.
- Target blood sugar ranges may be different for people with diabetes. Always follow your doctor's recommendations.
- For the A1C test, the result is expressed as a percentage, reflecting the average blood sugar control over the past 2-3 months.
Consult with your healthcare provider to understand your individual target blood sugar ranges and what your test results mean for your health. This blood sugar chart serves as a helpful reference, but it is not a substitute for professional medical advice.
Factors That Can Affect Blood Sugar Levels
Many factors can influence blood sugar levels, including:
- Food and Diet: The type, amount, and timing of meals and snacks significantly impact blood sugar. Carbohydrates raise blood sugar levels, so it's essential to balance carbohydrate intake with protein and healthy fats.
- Physical Activity: Exercise helps lower blood sugar by increasing insulin sensitivity and allowing your muscles to use glucose for energy.
- Medications: Certain medications, such as insulin, oral diabetes drugs, and steroids, can affect blood sugar levels.
- Stress: Stress hormones can raise blood sugar levels.
- Illness: Illness can also affect blood sugar levels, often increasing them.
- Dehydration: Dehydration can lead to more concentrated blood sugar levels, which can appear as if your blood sugar is higher than it actually is.
- Menstrual Cycle: Hormonal changes during the menstrual cycle can affect blood sugar levels in women.
Being aware of these factors and their potential impact on your blood sugar levels is crucial for effective management and maintaining stable glucose control.
Tips for Maintaining Healthy Blood Sugar Levels
Adopting healthy lifestyle habits can significantly contribute to maintaining healthy blood sugar levels and preventing complications. Here are some practical tips:
- Eat a Balanced Diet: Focus on whole, unprocessed foods, including fruits, vegetables, lean proteins, and whole grains. Limit your intake of sugary drinks, processed foods, and refined carbohydrates.
- Exercise Regularly: Aim for at least 30 minutes of moderate-intensity exercise most days of the week. This could include activities like brisk walking, jogging, swimming, or cycling.
- Monitor Your Blood Sugar Regularly: If you have diabetes, check your blood sugar as directed by your doctor. Regular monitoring helps you understand how different factors affect your levels and allows you to adjust your treatment plan accordingly.
- 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.
- Stay Hydrated: Drink plenty of water throughout the day.
- Work Closely with Your Healthcare Team: Regularly communicate with your doctor, diabetes educator, and other healthcare professionals to ensure you are receiving the best possible care.
By implementing these strategies, you can take proactive steps to manage your blood sugar levels and improve your overall health and well-being. Remember that consistency and adherence to your doctor's recommendations are key to long-term success.
When to See a Doctor
It's important to consult with your doctor if you experience any of the following:
- Frequent Episodes of Hyperglycemia or Hypoglycemia: Discuss the frequency and severity of your high and low blood sugar episodes with your doctor to adjust your treatment plan, if necessary.
- Unexplained Weight Loss or Gain: Significant changes in weight, without changes to diet or exercise, can be a sign of underlying health issues.
- Increased Thirst or Frequent Urination: These are common symptoms of high blood sugar, indicating that your body is trying to get rid of excess glucose.
- Blurred Vision: High blood sugar can affect the lens of the eye, leading to blurred vision.
- Slow-Healing Wounds: High blood sugar can impair the body's ability to heal, increasing the risk of infections.
- Numbness or Tingling in Hands and Feet: This can be a sign of nerve damage (neuropathy) caused by high blood sugar.
