Blood Sugar Levels Chart for Adults: Fasting, Post-Meal & A1c Ranges
Understanding your blood sugar levels is crucial for maintaining good health, especially if you're managing diabetes or at risk of developing it. This article provides a comprehensive blood sugar levels chart for adults, covering fasting blood sugar, post-meal blood sugar, and A1c ranges. We'll explore what these numbers mean, how to interpret them, and what steps you can take to maintain healthy blood sugar levels.
Why Monitor Blood Sugar Levels?
Monitoring blood glucose levels helps you understand how your body is responding to food, exercise, and medication. Regular monitoring is essential for:

- Managing diabetes effectively.
- Preventing hyperglycemia (high blood sugar) and hypoglycemia (low blood sugar).
- Detecting early signs of insulin resistance or pre-diabetes.
- Making informed decisions about your diet and lifestyle.
Fasting Blood Sugar Levels Chart

Fasting blood sugar is measured after at least eight hours of fasting (no food or drinks except water). These levels provide a baseline for understanding how well your body regulates blood sugar overnight.
| Category | Fasting Blood Sugar Level (mg/dL) | Interpretation |
|---|---|---|
| Normal | Less than 100 | Healthy blood sugar level; no indication of diabetes. |
| Pre-diabetes | 100 to 125 | Increased risk of developing type 2 diabetes; lifestyle changes recommended. |
| Diabetes | 126 or higher (on two separate tests) | Indicates diabetes; further evaluation and treatment required. |
Post-Meal Blood Sugar Levels Chart
Post-meal blood sugar levels, also known as postprandial blood sugar, are measured one to two hours after you start eating. These levels reflect how your body processes the carbohydrates you consume.
| Category | Post-Meal Blood Sugar Level (mg/dL) | Interpretation |
|---|---|---|
| Normal | Less than 140 (2 hours after eating) | Indicates good blood sugar control after meals. |
| Pre-diabetes | 140 to 199 (2 hours after eating) | Suggests impaired glucose tolerance; lifestyle changes recommended. |
| Diabetes | 200 or higher (2 hours after eating) | Indicates diabetes; further evaluation and treatment required. |
A1c Levels Chart
The A1c test, also known as the glycated hemoglobin test, provides an average of your blood sugar levels over the past two to three months. It's a crucial tool for assessing long-term blood sugar control.

| Category | A1c Level (%) | Interpretation |
|---|---|---|
| Normal | Less than 5.7 | Indicates good long-term blood sugar control. |
| Pre-diabetes | 5.7 to 6.4 | Increased risk of developing type 2 diabetes; lifestyle changes recommended. |
| Diabetes | 6.5 or higher | Indicates diabetes; further evaluation and treatment required. |
Factors Affecting Blood Sugar Levels
Several factors can influence your blood sugar levels:
- Diet: The type and amount of carbohydrates you eat directly impact blood sugar.
- Physical Activity: Exercise helps your body use glucose for energy, lowering blood sugar levels.
- Medications: Certain medications, like insulin or oral diabetes drugs, can affect blood sugar.
- Stress: Stress hormones can increase blood sugar levels.
- Illness: Illness can disrupt blood sugar control.
- Sleep: Insufficient sleep can affect insulin sensitivity.
- Dehydration: Impacts blood glucose levels.
Tips for Maintaining Healthy Blood Sugar Levels
Here are some strategies to help maintain healthy blood glucose levels:
- Eat a balanced diet: Focus on whole grains, lean proteins, and plenty of fruits and vegetables.
- Engage in regular physical activity: Aim for at least 150 minutes of moderate-intensity exercise per week.
- Monitor your blood sugar regularly: Follow your doctor's recommendations for blood sugar testing.
- Take medications as prescribed: Adhere to your prescribed medication regimen if you have diabetes.
- Manage stress: Practice relaxation techniques like meditation or yoga.
- Get enough sleep: Aim for 7-8 hours of quality sleep per night.
- Stay hydrated: Drinking water throughout the day.
When to See a Doctor
It's essential to consult your doctor if you experience:
- Consistently high or low blood sugar readings.
- Symptoms of hyperglycemia (e.g., excessive thirst, frequent urination, blurred vision).
- Symptoms of hypoglycemia (e.g., shakiness, sweating, confusion).
- Unexpected changes in your A1c levels.
Your doctor can help you develop a personalized plan to manage your blood sugar levels and prevent complications associated with diabetes. Monitoring your blood sugar regularly, understanding the blood sugar levels chart, and adopting a healthy lifestyle are key to maintaining good health. Remember that individual target ranges may vary based on factors such as age and other health conditions, so always consult with your healthcare provider to determine what's right for you.
