What Is a Normal Blood Sugar Level? The Definitive Chart by Age

Understanding normal blood sugar levels is crucial for maintaining good health, preventing diabetes, and managing existing conditions. This article provides a comprehensive guide to healthy blood sugar ranges by age, offering valuable insights for everyone from children to seniors.

Why Monitoring Blood Sugar is Important

Regularly checking your blood sugar levels allows you to:

Identify potential problems early
Monitor the effectiveness of diabetes management plans
Make informed decisions about diet and lifestyle
Reduce the risk of long-term complications associated with diabetes

Failing to maintain healthy blood sugar can lead to serious health issues, including heart disease, kidney damage, nerve damage, and vision problems. Therefore, proactively managing your blood sugar is an investment in your long-term well-being.

Blood Sugar Levels: Key Terms and Definitions

Before diving into the chart, let's define some important terms:

Fasting Blood Sugar (FBS): Measured after at least eight hours of fasting (typically overnight).
Postprandial Blood Sugar (PPBS): Measured two hours after starting a meal.
HbA1c: Also known as glycated hemoglobin, this test provides an average of your blood sugar control over the past 2-3 months.
Normal Range: Blood sugar levels considered healthy for most individuals without diabetes.
Prediabetes: Blood sugar levels are higher than normal but not high enough to be diagnosed as type 2 diabetes.
Diabetes: Blood sugar levels are consistently elevated and require management.
