Blood Sugar Levels Chart for Adults: From Normal to Diabetes Diagnosis
Understanding your blood sugar levels is crucial for maintaining overall health and preventing serious conditions like diabetes. This comprehensive guide provides a clear blood sugar levels chart for adults, explaining what's considered normal, pre-diabetic, and diabetic. We'll also cover the importance of regular monitoring and what steps to take if your levels are abnormal.
Why Blood Sugar Levels Matter
Blood sugar, or glucose, is the primary source of energy for your body. It comes from the food you eat. Insulin, a hormone produced by the pancreas, helps glucose from food get into your cells to be used for energy.
When you have diabetes, your body either doesn't make enough insulin or can't effectively use the insulin it does make. This causes blood sugar levels to rise, potentially leading to serious health complications such as heart disease, kidney disease, nerve damage (neuropathy), and vision loss. Regular blood sugar monitoring is key to managing and preventing these issues.

Understanding the Blood Sugar Levels Chart
This chart provides a reference for understanding your blood sugar readings. It includes the commonly used measurements: milligrams per deciliter (mg/dL).
| 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 |
| Pre-diabetes | 100 to 125 | 140 to 199 | 5.7 to 6.4 |
| Diabetes | 126 or higher | 200 or higher | 6.5 or higher |
Key Terms Explained:
- Fasting Blood Sugar: This is your blood sugar level after not eating or drinking (except water) for at least eight hours, typically measured in the morning.
- 2-Hour Postprandial Blood Sugar: This is your blood sugar level two hours after starting a meal.
- A1C (Glycated Hemoglobin): This test measures your average blood sugar levels over the past 2-3 months. It provides a broader picture than a single blood sugar reading.
Normal Blood Sugar Levels for Adults
For most healthy adults without diabetes, normal blood sugar levels are:
- Fasting: Less than 100 mg/dL
- 2-Hour Postprandial: Less than 140 mg/dL
- A1C: Less than 5.7%
Maintaining these levels through a healthy lifestyle and balanced diet is crucial for preventing future health problems.
Pre-diabetes: What It Means and What to Do
Pre-diabetes means your blood sugar levels are higher than normal, but not high enough to be diagnosed with diabetes. It is a critical stage where lifestyle changes can significantly reduce your risk of developing type 2 diabetes. According to the chart, pre-diabetes ranges are:
- Fasting: 100 to 125 mg/dL
- 2-Hour Postprandial: 140 to 199 mg/dL
- A1C: 5.7 to 6.4%

If you're diagnosed with pre-diabetes:
- Talk to your doctor: They can provide personalized advice and monitor your condition.
- Make lifestyle changes: This includes adopting a healthier diet, increasing physical activity, and maintaining a healthy weight. Even losing a small amount of weight (5-7% of your body weight) can make a big difference.
Diabetes Diagnosis: Understanding Your Readings
Diabetes is diagnosed when your blood sugar levels consistently exceed certain thresholds. Based on the blood sugar levels chart, these thresholds are:
- Fasting: 126 mg/dL or higher
- 2-Hour Postprandial: 200 mg/dL or higher
- A1C: 6.5% or higher
If you're diagnosed with diabetes:
- Follow your doctor's instructions: This may include medication, diet changes, and regular blood sugar monitoring.
- Learn how to manage your condition: Diabetes requires ongoing management to prevent complications. Attend educational programs and consult with a registered dietitian.
Monitoring Your Blood Sugar Levels
Regular blood sugar monitoring is crucial for both diagnosing and managing diabetes. Your doctor will recommend the appropriate frequency based on your individual needs and treatment plan.
- Home Blood Glucose Monitoring: This involves using a blood glucose meter (glucometer) to check your blood sugar levels throughout the day. You'll need to prick your finger to obtain a small blood sample.
- Continuous Glucose Monitoring (CGM): CGM devices automatically track your blood sugar levels continuously throughout the day and night via a small sensor inserted under your skin. This provides a more comprehensive picture of your blood sugar trends.
Factors That Can Affect Blood Sugar Levels
Several factors can influence your blood sugar levels, including:
- Food: The type and amount of carbohydrates you eat.
- Physical Activity: Exercise helps lower blood sugar.
- Medications: Certain medications can affect blood sugar levels.
- Stress: Stress can raise blood sugar.
- Illness: Being sick can impact blood sugar levels.
- Dehydration: Staying hydrated helps maintain healthy blood sugar levels.
