Are Your Blood Sugar Levels Normal? A Guide by Age Group
Maintaining normal blood sugar levels is crucial for overall health and well-being. Blood sugar, or glucose, is the primary source of energy for our bodies. However, consistently high or low blood sugar can lead to serious health complications. Understanding what constitutes a normal range, especially as it varies across different age groups, is key to proactive health management. This guide provides a comprehensive overview of blood sugar levels, target ranges by age, testing methods, and tips for maintaining healthy levels.

Before diving into age-specific ranges, let's cover the fundamentals of blood sugar regulation. Insulin, a hormone produced by the pancreas, plays a vital role. It acts like a key, allowing glucose from the food we eat to enter our cells for energy. When insulin isn't produced sufficiently or the body becomes resistant to it (insulin resistance), glucose builds up in the bloodstream, leading to hyperglycemia (high blood sugar). Conversely, too much insulin or not enough glucose can cause hypoglycemia (low blood sugar).
- Hyperglycemia: Can lead to long-term complications like heart disease, nerve damage (neuropathy), kidney disease, and vision problems.
- Hypoglycemia: Can cause symptoms like shakiness, dizziness, sweating, confusion, and, in severe cases, loss of consciousness.
How Blood Sugar Levels Are Measured
Blood sugar levels are typically measured in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). Common tests include:
- Fasting Blood Sugar (FBS): Measured after at least eight hours of fasting.
- Postprandial Blood Sugar (PPBS): Measured two hours after starting a meal.
- A1C Test (Glycated Hemoglobin): Provides an average blood sugar level over the past 2-3 months.
- Random Blood Sugar: Measured at any time, regardless of when you last ate.
Normal Blood Sugar Levels by Age Group
Keep in mind that these are general guidelines. Your doctor may recommend slightly different targets based on your individual health needs and medical history.
Children (Under 18)
For children, maintaining stable blood glucose is particularly important for growth and development.
- Fasting Blood Sugar: 70-150 mg/dL
- Postprandial Blood Sugar: Less than 200 mg/dL
- A1C: Less than 7.5% is recommended for some, discuss with your pediatrician
Adults (18-59)
This age group is often the most active, making it vital to regulate blood sugar effectively to fuel daily activities and prevent long-term complications.

- Fasting Blood Sugar: 70-100 mg/dL (for those without diabetes); 80-130 mg/dL (for those with diabetes)
- Postprandial Blood Sugar: Less than 140 mg/dL (for those without diabetes); Less than 180 mg/dL (for those with diabetes)
- A1C: Less than 5.7% (normal); Less than 7% (for those with diabetes, according to ADA recommendations, though individualized targets may vary)
Seniors (60+)
As we age, our bodies become less efficient at processing glucose. Managing blood sugar levels is crucial for preventing complications like heart disease and cognitive decline.
- Fasting Blood Sugar: 80-110 mg/dL (for those without diabetes); 80-130 mg/dL (for those with diabetes)
- Postprandial Blood Sugar: Less than 140 mg/dL (for those without diabetes); Less than 180 mg/dL (for those with diabetes)
- A1C: Less than 5.7% (normal); Less than 7.5% or even 8% may be acceptable depending on individual health status and risk of hypoglycemia (for those with diabetes - consult with your doctor).
Important Note: These are general guidelines. Consult your doctor for personalized advice.
Factors That Can Affect Blood Sugar Levels
Numerous factors can influence blood sugar control:
- Diet: The type and amount of carbohydrates you consume significantly impact blood sugar.
- Physical Activity: Exercise helps lower blood sugar by increasing insulin sensitivity.
- Stress: Stress hormones can raise blood sugar levels.
- Illness: Infections and illnesses can affect glucose regulation.
- Medications: Certain medications, like corticosteroids, can increase blood sugar.
- Age: The efficiency of your body declines with age.
Tips for Maintaining Healthy Blood Sugar Levels
Adopting a healthy lifestyle is essential for maintaining healthy blood sugar:
- Eat a Balanced Diet: Focus on whole grains, lean protein, fruits, and vegetables. Limit sugary drinks and processed foods.
- Regular Exercise: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Monitor Blood Sugar Regularly: If you have diabetes or are at risk, check your blood sugar levels as directed by your doctor.
- Manage Stress: Practice stress-reducing techniques like yoga, meditation, or deep breathing exercises.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep each night.
- Stay Hydrated: Drink plenty of water throughout the day.
Conditions Associated with Abnormal Blood Sugar Levels
Here’s a quick look at conditions linked to unstable blood sugar levels:
| Condition | Description | Potential Complications |
|---|---|---|
| Diabetes (Type 1) | Autoimmune condition where the body doesn't produce insulin. | Heart disease, kidney disease, nerve damage, vision loss. |
| Diabetes (Type 2) | The body becomes resistant to insulin or doesn't produce enough. | Heart disease, stroke, nerve damage, kidney disease. |
| Prediabetes | Blood sugar levels are higher than normal but not high enough to be diagnosed as diabetes. | Increased risk of developing type 2 diabetes, heart disease, and stroke. |
| Gestational Diabetes | Develops during pregnancy, usually resolves after delivery. | Increased risk of developing type 2 diabetes later in life for both mother and child. |
| Hypoglycemia | Low blood sugar levels. | Confusion, seizures, loss of consciousness. Can be life-threatening if untreated. |
When to See a Doctor
If you experience frequent symptoms of high or low blood sugar, or if you're concerned about your blood sugar levels, consult your doctor. They can assess your individual risk factors, perform necessary tests, and recommend a personalized treatment plan. Early detection and management are crucial for preventing long-term complications associated with uncontrolled blood glucose.
