Monitoring your blood sugar levels provides valuable insights into how your body processes sugar (glucose). Consistently high or low blood sugar levels can indicate underlying health issues, such as diabetes or hypoglycemia. Regular monitoring allows you and your healthcare provider to:
- Detect and manage diabetes or prediabetes.
- Understand how diet, exercise, and medications affect your blood sugar.
- Prevent or delay long-term complications associated with diabetes, such as nerve damage, kidney disease, and heart disease.
- Identify trends and patterns in your blood sugar levels to adjust your treatment plan as needed.
Blood Sugar Levels Chart: Overview
This chart provides a general guideline. Individual targets may vary based on your age, health condition, and treatment plan. Always consult with your healthcare provider for personalized recommendations.
Fasting Blood Sugar Levels
Fasting blood sugar is measured after at least eight hours of not eating. It's a common test to screen for diabetes or prediabetes.
Postprandial (After-Meal) Blood Sugar Levels

Postprandial blood sugar is measured one to two hours after eating. This reading helps assess how your body responds to food.
Blood Sugar Levels Chart by Age, Fasting, and After Meals
| Age Group | Fasting Blood Sugar (mg/dL) | 2-Hour Postprandial (After-Meal) Blood Sugar (mg/dL) | HbA1c | Category |
|---|---|---|---|---|
| Children (Under 6) | 80-180 | Up to 200 | Target ranges vary greatly; Consult Pediatrician. | |
| Children (6-12) | 80-120 | Up to 140 | Target ranges vary greatly; Consult Pediatrician. | |
| Teens (13-19) | 70-150 | Up to 140 | Target ranges vary greatly; Consult Pediatrician. | |
| Adults (Non-Diabetic) | 70-99 | Less than 140 | Less than 5.7% | Normal |
| Adults (Prediabetic) | 100-125 | 140-199 | 5.7-6.4% | Increased risk of developing diabetes |
| Adults (Diabetic) | 80-130 | Less than 180 | 6.5% or higher (Target usually below 7%) | Diabetes |
| Seniors (65+) | 80-180 | 100-200 | Individual target depends on overall health and other factors. |
Note: These are general guidelines and targets may vary. Consult your healthcare provider for individualized goals.
HbA1c (Hemoglobin A1c): This test provides an average of your blood sugar levels over the past 2-3 months. It is a key indicator of long-term blood sugar control.
Factors Affecting Blood Sugar Levels
Several factors can influence your blood sugar levels:

- Diet: Carbohydrates have the greatest impact on blood sugar. Pay attention to portion sizes and choose complex carbs over simple sugars.
- Exercise: Physical activity can lower blood sugar by increasing insulin sensitivity.
- Medications: Certain medications, such as insulin and oral diabetes drugs, can lower blood sugar. Other medications, like steroids, can raise it.
- Stress: Stress hormones can raise blood sugar.
- Illness: Infections and illnesses can affect blood sugar levels.
- Hydration: Dehydration can concentrate blood sugar, leading to higher readings.
- Sleep: Insufficient sleep can disrupt hormone balance and affect blood sugar control.
- Menstrual cycle (for women): Hormonal fluctuations can impact blood sugar.
- Alcohol: Alcohol can initially lower blood sugar, but can lead to a rebound effect later.
Tips for Maintaining Healthy Blood Sugar Levels
Here are some practical tips to help you manage your blood sugar effectively:
- Follow a Balanced Diet: Choose whole grains, lean proteins, and plenty of fruits and vegetables.
- Monitor Carbohydrate Intake: Work with a registered dietitian or diabetes educator to determine the right amount of carbs for your needs.
- Engage in Regular Exercise: Aim for at least 150 minutes of moderate-intensity exercise per week.
- Monitor Your Blood Sugar Regularly: Use a glucose meter to track your blood sugar and identify trends.
- Stay Hydrated: Drink plenty of water throughout the day.
- Manage Stress: Practice stress-reducing techniques such as meditation, yoga, or deep breathing.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep per night.
- Follow Your Medication Plan: Take your diabetes medications as prescribed by your healthcare provider.
- Regular Doctor Visits: Have regular check-ups with your doctor to monitor your blood sugar and overall health.
Understanding Hypoglycemia and Hyperglycemia
- Hypoglycemia (Low Blood Sugar): Typically defined as blood sugar levels below 70 mg/dL. Symptoms can include shakiness, sweating, confusion, and dizziness. It requires immediate treatment with fast-acting carbohydrates.
- Hyperglycemia (High Blood Sugar): Typically defined as blood sugar levels above the target range set by your healthcare provider. Symptoms can include increased thirst, frequent urination, and blurred vision. It requires monitoring and potential adjustments to diet, exercise, or medication.
Blood Sugar Monitoring Devices
- Traditional Glucose Meters: Require a finger prick to obtain a blood sample for testing.
- Continuous Glucose Monitors (CGMs): Provide real-time blood sugar levels by using a sensor inserted under the skin. These devices offer continuous monitoring and can alert you to potential highs and lows.
- Flash Glucose Monitoring Systems: Similar to CGMs, but require you to scan a sensor to get a blood sugar reading.
When to Seek Medical Advice
Consult your healthcare provider if you experience any of the following:
- Consistently high or low blood sugar levels.
- Symptoms of hyperglycemia or hypoglycemia that do not improve with treatment.
- Changes in your medication or health status that affect your blood sugar.
- Difficulty managing your blood sugar despite following a healthy lifestyle and medication plan.
The Importance of Working with Healthcare Professionals
Managing blood sugar levels effectively often requires a team approach. A diabetes educator can provide personalized guidance on diet, exercise, and medication management. Consulting with a registered dietitian can help you develop a meal plan tailored to your needs. Your primary care physician or endocrinologist can provide ongoing monitoring and adjust your treatment plan as needed.
