What Are Normal Blood Sugar Levels? A Chart for Adults by Age
Understanding your blood sugar levels is crucial for maintaining good health and preventing serious complications like diabetes. Many factors can influence these levels, including age, diet, and overall health conditions. This article will provide a comprehensive overview of normal blood sugar ranges for adults of different age groups, helping you stay informed about your health.
Why Monitoring Blood Sugar Is Important
Regular blood sugar monitoring helps identify potential issues early on. Whether you have diabetes or are simply health-conscious, knowing your normal ranges can assist in managing your diet, exercise, and medication effectively. Uncontrolled blood sugar levels can lead to a variety of health problems, including heart disease, kidney damage, nerve damage, and vision loss.
Understanding Blood Sugar Measurements
Before diving into the chart, it's important to understand the different measurements used to describe blood sugar levels:
- Fasting Blood Sugar (FBS): Measured after at least eight hours of fasting. This test is often used to screen for prediabetes and diabetes.
- Postprandial Blood Sugar (PPBS): Measured two hours after starting a meal. It assesses how your body processes glucose after eating.
- HbA1c (Glycated Hemoglobin): Provides an average of your blood sugar control over the past two to three months. It doesn't require fasting.

This chart provides a general guideline. It's important to consult with a healthcare provider for personalized advice and interpretation. Remember, normal blood sugar levels can vary based on individual health conditions.
| Age Group | Fasting Blood Sugar (mg/dL) | Postprandial Blood Sugar (2 hours after meal) (mg/dL) | HbA1c (%) |
|---|---|---|---|
| Adults (20-59 years) | 70-99 | Less than 140 | Below 5.7 |
| Older Adults (60+ years) | 80-110 | Less than 160 | Below 7.0 (Target may vary based on individual health) |
| Adults with Diabetes | 80-130 | Less than 180 | Below 7.0 (Target set by healthcare provider) |
Note: These ranges are general guidelines. Your healthcare provider may recommend different targets based on your individual circumstances, medical history, and other health conditions. For diabetic blood sugar levels, consulting with a healthcare professional is essential.
Factors Affecting Blood Sugar Levels
Numerous factors can influence your blood sugar levels, causing them to fluctuate throughout the day:
- Diet: Consuming sugary foods and refined carbohydrates can cause rapid spikes in blood sugar.
- Physical Activity: Exercise helps lower blood sugar by increasing insulin sensitivity and using glucose for energy.
- Stress: Stress hormones can increase blood sugar levels.
- Medications: Certain medications, such as steroids, can raise blood sugar.
- Illness: Infections and illnesses can also affect blood sugar levels.
- Age: As you age, your body's ability to regulate blood sugar may decrease.
How to Maintain Healthy Blood Sugar Levels
Maintaining healthy blood sugar levels involves a combination of lifestyle changes and, in some cases, medical interventions. Here are some practical tips:
- Eat a Balanced Diet: Focus on whole foods, lean proteins, and complex carbohydrates. Limit processed foods, sugary drinks, and excessive amounts of simple sugars.
- Engage in Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity exercise per week.
- Monitor Your Blood Sugar Regularly: Use a blood glucose meter as directed by your healthcare provider, especially if you have diabetes.
- Stay Hydrated: Drink plenty of water to help your kidneys flush out excess sugar.
- Manage Stress: Practice relaxation techniques such as meditation, yoga, or deep breathing exercises.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep each night to support overall metabolic health.
- Work Closely with Your Healthcare Provider: Regularly consult with your doctor or a certified diabetes educator to manage your blood sugar effectively.
Recognizing the Symptoms of High and Low Blood Sugar
Being aware of the symptoms of high blood sugar (hyperglycemia) and low blood sugar (hypoglycemia) can help you take prompt action and prevent serious complications.
Symptoms of High Blood Sugar (Hyperglycemia)
- Frequent urination
- Increased thirst
- Blurred vision
- Fatigue
- Slow-healing sores
- Unexplained weight loss
Symptoms of Low Blood Sugar (Hypoglycemia)
- Shakiness
- Sweating
- Dizziness
- Confusion
- Irritability
- Hunger
- Rapid heartbeat
If you experience these symptoms regularly, it's crucial to seek medical attention immediately.
Blood Sugar Levels and Diabetes
Diabetes is a condition characterized by elevated blood sugar levels. There are primarily two types:

- Type 2 Diabetes: A condition where the body does not use insulin effectively or doesn't produce enough insulin.

Gestational diabetes occurs during pregnancy and typically resolves after delivery. Prediabetes is a condition where blood sugar levels are higher than normal but not high enough to be diagnosed as diabetes. Identifying and managing prediabetes is vital to preventing the progression to type 2 diabetes.
Blood Sugar Monitoring Devices
Various devices are available for monitoring blood sugar levels:
