What is a Normal Blood Sugar Level? A Chart for Every Age
Understanding normal blood sugar levels is crucial for maintaining good health, regardless of your age. Whether you're monitoring your own levels or caring for someone else, knowing what's considered normal—and when to be concerned—is vital. This comprehensive guide will provide a breakdown of normal blood sugar ranges for various age groups, factors influencing these levels, and steps you can take to manage them effectively.
Why Monitor Blood Sugar Levels?
Before diving into the specifics, let's understand why tracking blood sugar, or glucose, is so important. Glucose is your body's primary source of energy, derived from the food you eat. Insulin, a hormone produced by the pancreas, helps glucose enter your cells to be used for energy.
When blood sugar levels are consistently too high (hyperglycemia) or too low (hypoglycemia), it can indicate a problem with your body's ability to regulate glucose effectively. Prolonged periods of either can lead to serious health complications, including:
- Diabetes: A chronic condition where the body either doesn't produce enough insulin or can't effectively use the insulin it produces.
- Heart Disease: High blood sugar can damage blood vessels and increase the risk of cardiovascular problems.
- Kidney Disease: Uncontrolled diabetes is a leading cause of kidney failure.
- Nerve Damage (Neuropathy): High blood sugar can damage the nerves, leading to pain, numbness, and other issues.
- Eye Damage (Retinopathy): Diabetes can damage the blood vessels in the retina, potentially leading to blindness.
Regular blood sugar monitoring allows individuals to detect potential problems early and take proactive steps to manage their health.
Factors Influencing Blood Sugar Levels
Several factors can influence blood sugar levels, including:

- Diet: Carbohydrate intake has the most significant impact on blood sugar.
- Physical Activity: Exercise helps lower blood sugar by increasing insulin sensitivity and using glucose for energy.
- Stress: Stress hormones can raise blood sugar levels.
- Illness: Infections and illnesses can also affect blood sugar.
- Medications: Certain medications, such as steroids, can increase blood sugar.
- Age: Blood sugar levels can naturally rise with age.
- Underlying Medical Conditions: Conditions like diabetes, insulin resistance, and hormonal imbalances directly affect blood sugar.
Normal Blood Sugar Levels Chart by Age
The following chart outlines generally accepted normal blood sugar ranges for different age groups. Keep in mind that these are general guidelines, and your doctor may recommend different targets based on your individual health status. Blood sugar levels are typically measured in milligrams per deciliter (mg/dL).
| Age Group | Fasting Blood Sugar (mg/dL) | 2 Hours After Eating (mg/dL) | A1c |
|---|---|---|---|
| Children (Under 6) | 80-180 mg/dL | Up to 180 mg/dL | N/A - Consult Doctor |
| Children (6-12) | 80-120 mg/dL | Up to 140 mg/dL | N/A - Consult Doctor |
| Teenagers (13-19) | 70-150 mg/dL | Up to 140 mg/dL | N/A - Consult Doctor |
| Adults (Non-Diabetic) | 70-99 mg/dL | Less than 140 mg/dL | Less than 5.7% |
| Adults (Diabetic) | 80-130 mg/dL | Less than 180 mg/dL | Less than 7.0% (as advised by your doctor) |
| Seniors (65+) | 80-130 mg/dL | Less than 180 mg/dL | Less than 7.5% (as advised by your doctor) |
- Fasting Blood Sugar: Measured after at least 8 hours of fasting (no food or drink except water).
- 2 Hours After Eating (Postprandial): Measured 2 hours after the start of a meal.
- A1c: This measures your average blood sugar level over the past 2-3 months.

Important Note: Always consult with a healthcare professional to determine the best blood sugar target range for your individual needs and medical history. These are general guidelines only. The A1c Targets are only for Adults and Seniors with Diabetes. Discuss acceptable levels for Children and Teenagers with their Pediatrician.
Understanding Blood Sugar Levels for Diabetics
For individuals with diabetes, maintaining stable blood sugar levels is critical. The target ranges are often different from those without diabetes and are individualized based on the type of diabetes, medications, and overall health.
- Type 1 Diabetes: Requires lifelong insulin therapy to regulate blood sugar. Monitoring is frequent and crucial.
- Type 2 Diabetes: Often managed with lifestyle changes, oral medications, and sometimes insulin.
- Gestational Diabetes: Occurs during pregnancy and usually resolves after delivery, but increases the risk of developing type 2 diabetes later in life.
Regardless of the type of diabetes, regular communication with a healthcare team and adherence to a tailored management plan are essential.
