What Is a Normal Blood Sugar Level? [Updated Blood Sugar Chart Inside]
Understanding normal blood sugar levels is crucial for maintaining good health and preventing serious complications like diabetes. Blood sugar, or glucose, is your body's primary source of energy. Keeping it within a healthy range is essential for proper organ function and overall well-being. Let's dive into what constitutes normal, factors that influence it, and how to maintain healthy levels.
Why Blood Sugar Levels Matter
Your blood sugar levels impact everything from your energy levels to your cognitive function. When blood sugar levels are consistently high (hyperglycemia) or low (hypoglycemia), it can lead to a cascade of health problems.
- Hyperglycemia: Chronically high blood sugar can damage blood vessels, nerves, and organs, increasing the risk of heart disease, kidney disease, nerve damage (neuropathy), and vision problems (retinopathy).
- Hypoglycemia: Low blood sugar can cause dizziness, confusion, seizures, and even loss of consciousness if left untreated.
Therefore, maintaining a stable blood sugar level is not just about avoiding diabetes; it's about optimizing your health and preventing potential long-term complications. A Simple Blood Sugar Chart Explained For Persons With Diabetes
Factors That Influence Blood Sugar Levels

Several factors can influence your blood sugar levels throughout the day and over time. These include:
- Diet: The types and amounts of carbohydrates you consume have the most significant impact on blood sugar.
- Physical Activity: Exercise helps your body use glucose for energy, lowering blood sugar levels.
- Stress: Stress hormones can increase blood sugar levels.
- Medications: Certain medications, such as steroids, can raise blood sugar.
- Illness: Being sick can affect blood sugar levels, sometimes causing them to rise.
- Age: Blood sugar levels tend to increase with age.
- Hormonal Changes: Fluctuations in hormones, particularly during menstruation or pregnancy, can affect blood sugar.
Understanding these factors can help you anticipate and manage fluctuations in your blood sugar.
Normal Blood Sugar Levels: A Detailed Chart
So, what exactly constitutes a "normal blood sugar level"? The following chart provides general guidelines. Keep in mind that these numbers may vary slightly depending on individual circumstances and testing methods. Consult with your doctor for personalized recommendations. The 5 Minute Habit That Can Help Lower Your Blood Sugar Daily
Time of Day | Normal Blood Sugar Range (mg/dL) for Non-Diabetics | Normal Blood Sugar Range (mg/dL) for Diabetics* |
---|---|---|
Fasting (After at least 8 hours of not eating) | 70-99 | 80-130 |
2 Hours After Eating | Less than 140 | Less than 180 |
Before Meals | N/A | 80-130 |
Bedtime | N/A | 90-150 |
*Note: Diabetic blood sugar targets are generally broader than those for non-diabetics. This is because the focus is on managing blood sugar to avoid significant highs and lows, rather than striving for "perfect" normal levels. Target ranges can vary based on individual needs.
Testing Your Blood Sugar
Regularly monitoring your blood sugar levels is essential, especially if you have diabetes, prediabetes, or a family history of diabetes. There are several ways to test your blood sugar:
- Fasting Blood Sugar Test: This test measures your blood sugar after an overnight fast (at least 8 hours). It's often used to screen for diabetes and prediabetes.
- A1C Test: The A1C test provides an average of your blood sugar levels over the past 2-3 months. It doesn't require fasting and is a common way to monitor blood sugar control in people with diabetes.
- Oral Glucose Tolerance Test (OGTT): This test involves drinking a sugary liquid and then having your blood sugar measured at specific intervals over a period of two hours. It's often used to diagnose gestational diabetes.
- Home Blood Glucose Monitoring (HBGM): This involves using a blood glucose meter to check your blood sugar several times a day. This is common for people with diabetes to help manage their insulin or medications and adjust their diet and exercise.
Tips for Maintaining Healthy Blood Sugar Levels
Maintaining healthy blood sugar levels involves a combination of lifestyle changes and, in some cases, medication. Here are some practical tips:
- Eat a Balanced Diet: Focus on whole, unprocessed foods, including plenty of fruits, vegetables, and whole grains. Limit your intake of sugary drinks, processed foods, and refined carbohydrates.
- Control Carbohydrate Intake: Pay attention to the amount of carbohydrates you consume at each meal and snack. Consider using the carbohydrate counting method.
- Get Regular Exercise: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Manage Stress: Practice stress-reducing techniques like yoga, meditation, 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.
- Monitor Your Blood Sugar Regularly: If you have diabetes or prediabetes, follow your doctor's recommendations for blood sugar monitoring.
- Take Medications as Prescribed: If you've been prescribed medication for diabetes, take it as directed by your doctor.
- Work with a Healthcare Professional: Consult with a doctor, registered dietitian, or certified diabetes educator for personalized advice and support.
When to See a Doctor
It's crucial to consult a doctor if you experience any of the following:
- Frequently elevated blood sugar levels
- Symptoms of hyperglycemia or hypoglycemia
- Unexplained weight loss or gain
- Increased thirst or urination
- Blurred vision
- Slow-healing sores or cuts
- Numbness or tingling in your hands or feet
