What is a Normal Blood Sugar Level? A Complete Blood Sugar Chart

Understanding normal blood sugar levels is crucial for maintaining overall health and preventing serious complications like diabetes. This comprehensive guide provides a detailed blood sugar chart and explains what levels are considered healthy, prediabetic, or diabetic. Common Mistakes People Make When Trying To Stabilize Blood Sugar

Why Monitoring Blood Sugar Matters

Your blood glucose level, or blood sugar, is the amount of glucose (sugar) present in your blood. Glucose is your body's primary source of energy, and it comes from the food you eat. The hormone insulin, produced by the pancreas, helps glucose enter your cells to be used for energy.

When you have high blood sugar (hyperglycemia), it can damage blood vessels and organs over time, leading to complications like heart disease, kidney disease, nerve damage (neuropathy), and vision problems. On the other hand, low blood sugar (hypoglycemia) can cause symptoms like shakiness, confusion, and even loss of consciousness.

Therefore, monitoring your blood sugar levels is essential, especially if you have diabetes, prediabetes, or risk factors for developing diabetes. This chart will help you better understand and interpret blood sugar readings. How A 15 Minute Walk Can Help Manage Your Blood Sugar Level

Understanding Blood Sugar Measurements

Blood sugar levels are typically measured in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). In the United States, mg/dL is the standard unit. You’ll see both used in global research, though, so familiarity with both is helpful. You can easily convert between the two using online tools.

Blood Sugar Chart: Normal, Prediabetic, and Diabetic Ranges

The following chart provides general guidelines for blood sugar levels, according to the American Diabetes Association (ADA). Keep in mind that individual targets may vary based on age, health condition, and other factors. Always consult with your healthcare provider to determine the appropriate blood sugar goals for you.

Category	Fasting Blood Sugar (mg/dL)	2-Hour Postprandial (After Eating) Blood Sugar (mg/dL)	A1C
Normal	Less than 100	Less than 140	Less than 5.7%
Prediabetes	100 to 125	140 to 199	5.7% to 6.4%
Diabetes	126 or higher	200 or higher	6.5% or higher

Important Notes:

• Fasting blood sugar is measured after at least eight hours of not eating or drinking anything other than water.
• 2-hour postprandial blood sugar is measured two hours after starting a meal.
• A1C is a blood test that reflects your average blood sugar level over the past 2-3 months.

What Affects Blood Sugar Levels?

Many factors can influence your blood sugar, including:

• Food and Drinks: Carbohydrates are broken down into glucose, so the amount and type of carbs you consume directly affect your blood sugar.
• Physical Activity: Exercise helps lower blood sugar by allowing your cells to use glucose more efficiently.
• Medications: Certain medications, such as steroids, can increase blood sugar levels.
• Stress: Stress hormones can raise blood sugar.
• Illness: Being sick can also cause blood sugar to rise.
• Sleep: Lack of sleep can negatively affect insulin sensitivity, leading to higher blood sugar.
• Menstrual Cycle: Hormone fluctuations during menstruation can impact blood sugar levels.

Symptoms of High and Low Blood Sugar

Recognizing the symptoms of high blood sugar (hyperglycemia) and low blood sugar (hypoglycemia) is important for managing your health.

Symptoms of Hyperglycemia (High Blood Sugar):

• Frequent urination
• Increased thirst
• Blurred vision
• Fatigue
• Headache

Symptoms of Hypoglycemia (Low Blood Sugar):

• Shakiness
• Sweating
• Dizziness
• Confusion
• Hunger
• Irritability
• Rapid heartbeat
• In severe cases, loss of consciousness or seizures.

If you experience any of these symptoms, check your blood sugar immediately. If your blood sugar is too high or too low, follow your doctor's recommendations for managing it. For low blood sugar, the "15-15 rule" is commonly advised: consume 15 grams of quick-acting carbohydrates, wait 15 minutes, then recheck your blood sugar. If it's still low, repeat the process.

Tips for Maintaining Healthy Blood Sugar Levels

Here are some practical tips to help you maintain healthy blood sugar levels:

• Eat a Balanced Diet: Focus on whole, unprocessed foods, including fruits, vegetables, whole grains, lean protein, and healthy fats. Limit sugary drinks, processed foods, and refined carbohydrates.
• Exercise Regularly: Aim for at least 150 minutes of moderate-intensity exercise per week. This can include brisk walking, swimming, or cycling.
• Monitor Your Blood Sugar: If you have diabetes or prediabetes, check your blood sugar regularly as directed by your doctor. Keep a record of your readings and share them with your healthcare provider.
• Manage Stress: Find healthy ways to manage stress, such as meditation, yoga, or spending time in nature.
• Get Enough Sleep: Aim for 7-8 hours of quality sleep each night.
• Stay Hydrated: Drink plenty of water throughout the day to help regulate blood sugar levels.
• Work with a Healthcare Professional: A registered dietitian or certified diabetes educator can provide personalized guidance on diet and lifestyle modifications to help you manage your blood sugar.
• Maintain a Healthy Weight: If you are overweight or obese, losing even a small amount of weight can significantly improve your blood sugar control.
