A Normal Blood Sugar Levels Chart by Age helps you understand what healthy blood sugar looks like at every stage of life. By knowing what’s normal for your age group, you can spot early signs of diabetes, hypoglycemia, or other blood sugar-related issues before they become serious problems.
Common causes of abnormal blood sugar include poor diet, lack of exercise, stress, and certain medical conditions. For example, research shows that nearly 1 in 10 adults worldwide are affected by diabetes, with risk increasing significantly as we age.
This guide provides a detailed normal blood sugar levels chart by age, helping you monitor and maintain healthy levels efficiently. You’ll find specific ranges for children, adults, and seniors.
Blood Sugar Levels
Blood sugar levels are crucial indicators of overall health, especially for those with diabetes. They reflect the amount of glucose in the blood, which serves as the primary energy source for cells and organs.
Healthy blood sugar levels can greatly affect your energy and mood. They also play a crucial role in your long-term health.
Insulin, a hormone produced by the pancreas, plays a vital role in regulating blood sugar levels. It allows glucose to enter cells, where it is used for energy, thus keeping blood sugar levels within a normal range.
Without enough insulin, or if the body cannot use insulin effectively, blood sugar levels can rise, leading to diabetes.
Normal Blood Sugar Levels by Age
Blood sugar levels can vary significantly with age due to differences in metabolism and insulin sensitivity. For instance, children and adolescents have different normal ranges compared to adults and older individuals.
For children aged 2 and above, normal fasting glucose levels range from 70 to 100 mg/dL, while children under 5 years old have a broader range of 80-200 mg/dL. Adolescents aged 12 years and above should aim for blood sugar levels from 70-150 mg/dL. These ranges reflect the changing metabolic needs and insulin sensitivity as children grow.
Adults and seniors also experience variations in blood sugar levels based on age and health conditions. It’s essential to recognize these differences and adjust blood sugar management strategies accordingly.
Normal Blood Sugar Levels by Age Group
Blood sugar levels vary significantly by age, with specific ranges established for different age groups.
Let’s delve into the details for each age group to provide a comprehensive understanding of normal blood sugar levels and the factors influencing them.
Blood Sugar Levels for Children (Ages 0-18)
For children under 5 years old, the acceptable blood sugar range is between 71-180 mg/dL. As children grow older, from age 5 onwards, they should maintain blood sugar levels between 71-150 mg/dL. These ranges ensure that children have enough energy for growth and daily activities.
Children require regular blood glucose monitoring, especially before meals and at bedtime, to manage their targets effectively and prevent abnormal levels.
Blood Sugar Levels for Adults (Ages 19-45)

Fasting Blood Sugar Levels
Fasting blood sugar tests are conducted to measure glucose levels after not eating for at least eight hours. This test is crucial for diagnosing diabetes and managing overall health.
For accurate fasting plasma glucose tests, fasting for at least eight hours is required. A normal fasting blood glucose level is 125 mg/dL or less.
The American Diabetes Association classifies fasting plasma glucose over 125 mg/dL as indicative of diabetes. Tracking fasting blood sugar levels aids in managing targets and preventing abnormalities.
Postprandial Blood Sugar Levels
Postprandial blood sugar levels refer to glucose levels measured after eating. Normal postprandial blood sugar levels for adults should be less than 140 mg/dL. This measurement is crucial for managing overall health and preventing diabetes-related complications.
Individuals with diabetes should target their postprandial blood sugar levels. Specifically, these levels should be under 180 mg/dL two hours after consuming a meal. Keeping track of these levels aids in managing sugar targets and preventing abnormalities.
Factors Influencing Blood Sugar Levels
Dietary choices, particularly carbohydrate content, significantly influence blood glucose levels. Carbohydrates increase blood sugar levels more than proteins do. They also raise levels more than fats.
Being aware of how different foods impact your blood sugar is vital for effective management.
Physical activity can lead to immediate decreases in blood sugar levels post-exercise and can lower glucose levels for up to 24 hours. Stress can elevate blood sugar levels because of hormonal changes.
Several factors influence blood sugar levels:
Certain medications, like corticosteroids, can raise blood sugar levels.
Alcohol, antibiotics, and insulin levels can also impact blood sugar levels.
Medical conditions such as infections or illnesses can lead to increased blood glucose levels.
Stress, illness, insufficient insulin, insulin resistance, and lack of physical activity can all cause hyperglycemia.
High Blood Sugar (Hyperglycemia)
High blood sugar is identified as a condition where glucose levels exceed normal limits, often leading to various symptoms like excessive thirst and frequent urination.
People with diabetes are particularly susceptible to hyperglycemia and abnormal blood sugar levels, which can arise from consuming excessive carbohydrates or inadequate insulin intake.
In severe cases, prolonged hyperglycemia can lead to complications such as eye damage, kidney issues, and cardiovascular diseases. Management of high blood sugar often involves lifestyle modifications, medication, and regular monitoring of glucose levels.
If blood sugar levels are consistently high, they can lead to long-term health issues and complications. Frequent monitoring and a healthy lifestyle are vital to prevent these complications.
Low Blood Sugar (Hypoglycemia)
Hypoglycemia is identified by low blood sugar levels that reach 70 mg/dL or lower. This condition can lead to various health issues if not addressed.
Common causes of hypoglycemia include:
Alcohol consumption without food
Certain medications
Long-term fasting
Pancreatic tumors
Symptoms of low blood sugar can include sweating, shakiness, headache, paleness, or nausea. If blood sugar drops below 55 mg/dL, immediate action, such as calling 911 or using injectable glucagon, is recommended.
Repeated low blood sugar episodes can cause hypoglycemia unawareness, underscoring the need for effective management. Following the 15:5 rule is an effective way to treat low blood sugar.
Monitoring Blood Glucose Levels
Keeping track of blood glucose levels determines if they are within a healthy range, which helps prevent complications.
Logging blood glucose results regularly gives a comprehensive overview of the effectiveness of diabetes management strategies.
Blood sugar can be monitored using various methods, including a blood glucose meter and a continuous glucose monitor (CGM). At-home glucometer testing involves measuring the sugar level in a blood sample taken from a fingertip.
Calibrating with a traditional blood glucose meter may be needed to ensure CGM readings are accurate. Daily testing is still required to confirm CGM readings, even when using a CGM.
Blood Sugar Management Tips
Maintaining healthy blood sugar levels involves a combination of diet, exercise, and monitoring. Balanced meals rich in fruits, vegetables, and whole grains significantly aid in blood sugar control.
Drinking water instead of high-calorie beverages maintains optimal hydration and blood sugar levels.
Regular aerobic exercise helps to utilize blood sugar for energy, improving insulin sensitivity. Weight management is crucial; even modest weight loss can enhance blood sugar regulation. A continuous glucose monitor (CGM) offers real-time data on glucose levels, enabling users to track changes over time.
Some practical tips include:
Eating balanced meals with a mix of carbs, proteins, and fats.
Engaging in regular physical activity, such as walking or cycling.
Drinking plenty of water to stay hydrated.
Using CGMs to reduce the frequency of finger-stick tests while providing alerts for high or low glucose levels.
When to Seek Medical Attention
Symptoms of high blood sugar include fatigue, increased hunger, blurred vision, and slow wound healing. Persistent symptoms warrant a call to a healthcare professional.
Severe cases of hypoglycemia may progress to confusion, unresponsiveness, or seizures. Drowsiness and confusion can indicate severe hypoglycemia in children. Fainting and seizures can occur as a serious consequence of severely low blood glucose levels.
If your blood sugar is 240 mg/dL or higher, check for ketones and contact your doctor immediately to prevent complications and manage your health effectively.
