Understanding blood sugar levels is critical for managing your health, especially as you age. Whether you're monitoring for diabetes, prediabetes, or simply aiming for optimal wellness, knowing the target ranges can make a significant difference. This article provides a comprehensive blood sugar levels chart for adults, broken down by age and after eating, ensuring you have the information you need at your fingertips.
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. Your pancreas produces insulin, a hormone that helps glucose enter your cells to be used for energy. When you have diabetes or prediabetes, your body either doesn’t make enough insulin or can’t effectively use the insulin it produces, leading to elevated blood sugar levels.
Chronically high blood sugar levels can damage organs and tissues, leading to serious health complications such as:
- Heart disease
- Kidney disease
- Nerve damage (neuropathy)
- Eye damage (retinopathy)
Therefore, regular monitoring and maintaining healthy blood sugar levels are essential for preventing these complications and promoting overall well-being.

Different age groups have slightly varying blood sugar level targets. Factors such as decreased kidney function, increased frailty, and cognitive decline can influence the target ranges for older adults.
Age Group | Fasting Blood Sugar (mg/dL) | 2-Hour Postprandial (After Eating) Blood Sugar (mg/dL) | HbA1c (%) |
---|---|---|---|
Adults (Under 60) Without Diabetes | 70-100 | Less than 140 | Less than 5.7 |
Adults (Under 60) With Diabetes | 80-130 | Less than 180 | Less than 7.0 (or as advised by doctor) |
Older Adults (60+) Without Diabetes | 70-110 | Less than 160 | Less than 6.5 |
Older Adults (60+) With Diabetes | 80-150 | Less than 200 | Less than 8.0 (or as advised by doctor) |
Important Considerations:
- These are general guidelines. Your doctor may recommend different target ranges based on your individual health status and other factors.
- HbA1c is a measure of your average blood sugar levels over the past 2-3 months.
Blood Sugar Levels After Eating (Postprandial)
Postprandial blood sugar refers to the blood sugar levels after eating. It’s essential to monitor these levels as they provide valuable insights into how your body responds to food and insulin. Generally, blood sugar levels rise after a meal, but the goal is to ensure they don't spike too high.
Here's a more detailed look:
- Normal Blood Sugar 2 Hours After Eating: For most adults without diabetes, a blood sugar level of less than 140 mg/dL is considered normal two hours after starting a meal.
- Target Blood Sugar After Eating for Diabetics: Individuals with diabetes are often advised to maintain their blood sugar below 180 mg/dL two hours after eating, but this can vary based on individual factors and doctor's recommendations.
- Factors Influencing Postprandial Blood Sugar: The type and quantity of food consumed, physical activity levels, medications, and overall health all influence postprandial blood sugar.
Monitoring Your Blood Sugar
Regular blood sugar monitoring is a crucial aspect of managing diabetes and maintaining overall health. Here are common methods:
- Glucose Meter: A glucose meter requires a small blood sample, usually taken from a fingertip. You insert the test strip into the meter, apply the blood sample, and the meter displays your blood sugar level.
- Continuous Glucose Monitoring (CGM): A CGM device uses a small sensor inserted under the skin to continuously monitor glucose levels. It provides real-time data and trends, offering a more comprehensive view of blood sugar fluctuations.
It's essential to record your blood sugar readings and discuss them with your healthcare provider to adjust your treatment plan as needed.

Here are practical tips to help keep your blood sugar levels within the target range:
- Follow a Balanced Diet: Focus on whole foods, including fruits, vegetables, lean proteins, and whole grains. Limit processed foods, sugary drinks, and refined carbohydrates.
- Regular Exercise: Physical activity helps improve insulin sensitivity and lowers blood sugar. Aim for at least 150 minutes of moderate-intensity exercise per week.
- Medication Management: If you have diabetes, take your medications as prescribed by your doctor. Don’t skip doses or change the dosage without consulting your healthcare provider.
- Portion Control: Pay attention to portion sizes to prevent overeating and subsequent blood sugar spikes.
- Stress Management: Stress can affect blood sugar levels. Practice relaxation techniques such as meditation, yoga, or deep breathing exercises.
- Stay Hydrated: Drink plenty of water to help regulate blood sugar and support overall health.
- Regular Monitoring: Monitor your blood sugar levels as recommended by your healthcare provider and keep a record of your readings.
Symptoms of High and Low Blood Sugar
Recognizing the symptoms of high and low blood sugar is crucial for prompt action.
Symptoms of High Blood Sugar (Hyperglycemia):
- Increased thirst
- Frequent urination
- Blurred vision
- Fatigue
- Headaches
Symptoms of Low Blood Sugar (Hypoglycemia):
- Shakiness
- Sweating
- Dizziness
- Hunger
- Confusion
- Irritability
If you experience these symptoms, check your blood sugar and take appropriate action, such as eating a quick source of carbohydrates if your blood sugar is low, or contacting your healthcare provider if your blood sugar is consistently high.
Conclusion
Maintaining healthy blood sugar levels is paramount for overall well-being and preventing diabetes-related complications. By understanding the target ranges based on age and post-meal times, monitoring your levels regularly, and adopting healthy lifestyle habits, you can effectively manage your blood sugar and enjoy a healthier life. Always consult with your healthcare provider to create a personalized plan tailored to your specific needs.
