Blood sugar, or blood glucose, refers to the amount of glucose present in your blood. Glucose is a type of sugar that comes from the food you eat, and it's the primary source of energy for your body. Your body tightly regulates blood sugar levels through a complex process involving insulin, a hormone produced by the pancreas.

Maintaining healthy blood glucose levels is important because:
- It provides your cells with the energy they need to function correctly.
- It helps prevent health problems like fatigue, blurred vision, and frequent urination.
- It reduces the risk of developing more serious conditions like prediabetes and type 2 diabetes.
Normal Blood Sugar Levels for Non-Diabetics
The normal range for blood sugar levels in non-diabetic individuals typically falls within these guidelines:
- Fasting Blood Sugar: 70-99 mg/dL (measured after an overnight fast)
- Two Hours After Eating: Less than 140 mg/dL
These ranges can vary slightly depending on the lab and the testing method used. Consult with your doctor for personalized advice.
Blood Sugar Chart for Non-Diabetics
This chart provides a quick reference for normal blood sugar ranges.
| Time of Day | Normal Blood Sugar Range (mg/dL) |
|---|---|
| Fasting (After at least 8 hours of fasting) | 70-99 |
| 2 Hours After Eating | Less than 140 |
Factors That Can Affect Blood Sugar Levels
Even in non-diabetics, blood sugar levels can fluctuate due to various factors:

- Diet: Consuming sugary drinks, processed foods, and large meals can lead to temporary spikes in blood sugar.
- Physical Activity: Exercise helps improve insulin sensitivity and can lower blood sugar levels.
- Stress: Stress hormones can elevate blood sugar.
- Medications: Some medications can affect blood sugar levels.
- Illness: Illness, especially infections, can temporarily increase blood sugar.
- Dehydration: Dehydration can concentrate blood sugar making it appear higher.
- Sleep: Lack of sleep can impair insulin sensitivity and affect blood glucose levels.
How to Maintain Healthy Blood Sugar Levels
Maintaining healthy blood sugar levels involves adopting a healthy lifestyle:
- Eat a Balanced Diet: Focus on whole grains, lean protein, healthy fats, and plenty of fruits and vegetables. Limit sugary drinks and processed foods.
- Exercise Regularly: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Manage Stress: Practice relaxation techniques like yoga, meditation, or deep breathing.
- Stay Hydrated: Drink plenty of water throughout the day.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep each night.
- Regular Check-ups: Discuss any concerns or risk factors with your doctor during your annual checkup.
When to Be Concerned About Blood Sugar
While occasional fluctuations in blood sugar are normal, consistent elevation or frequent spikes could indicate a problem. If you experience any of the following, consult your doctor:
- Consistently elevated fasting blood sugar levels.
- Frequent feelings of thirst or hunger.
- Frequent urination, especially at night.
- Unexplained weight loss.
- Blurred vision.
- Slow-healing sores or frequent infections.
- Fatigue.
These symptoms could be signs of prediabetes or type 2 diabetes, which require medical attention.
Monitoring Your Blood Sugar (Even Without Diabetes)
While routine blood sugar monitoring is more common for individuals with diabetes, it can also be beneficial for non-diabetics, especially those with risk factors for developing the condition. Risk factors include:
- Family history of diabetes.
- Overweight or obesity.
- Physical inactivity.
- High blood pressure.
- High cholesterol.
- History of gestational diabetes.
If you have risk factors, talk to your doctor about whether blood glucose monitoring is right for you. They may recommend occasional testing using a home glucose meter or regular A1c tests to assess your average blood sugar levels over time. This monitoring is useful for early detection and proactive management of prediabetes and diabetes. Remember to discuss blood sugar targets with your doctor to align them with your individual circumstances.
Understanding Prediabetes
Prediabetes means that your blood sugar levels are higher than normal, but not high enough to be diagnosed as type 2 diabetes. It's a serious health condition because it increases your risk of developing type 2 diabetes, heart disease, and stroke. Prediabetes often has no symptoms, so getting your blood sugar tested is crucial. Lifestyle changes, such as diet and exercise, can often help to prevent prediabetes from progressing to type 2 diabetes.
Conclusion
Maintaining healthy blood sugar is essential for overall well-being, regardless of whether you have diabetes. Understanding what's considered normal, identifying risk factors, and adopting a healthy lifestyle can help you maintain stable blood glucose levels and prevent the development of diabetes. Use the information and chart in this guide as a starting point and consult with your doctor for personalized advice and monitoring.
