Your Complete Blood Sugar Levels Chart (By Age, Fasting & After Eating)
Understanding blood sugar levels is crucial for maintaining overall health and preventing diabetes. This comprehensive guide will provide you with detailed blood sugar charts for different age groups, fasting levels, and post-meal readings. We'll also cover factors that can affect these levels and when to seek professional medical advice. This information should be used for educational purposes only, and is not a substitute for professional medical advice. Always consult with your healthcare provider for diagnosis and treatment.
Why Monitor Blood Sugar Levels?
Monitoring your blood sugar levels helps you and your doctor understand how your body is processing glucose, the primary source of energy. Regular monitoring is especially important for individuals with diabetes or pre-diabetes, as it allows for timely adjustments in diet, exercise, or medication to maintain healthy levels. Even if you don't have diabetes, understanding normal ranges can help you make informed lifestyle choices and identify potential health risks early on. Uncontrolled blood sugar can lead to serious health complications, including heart disease, kidney damage, and nerve damage.
Understanding the Different Types of Blood Sugar Tests
Before diving into the charts, let's clarify the different types of blood sugar tests commonly used:
- Fasting Blood Sugar (FBS): Measured after at least 8 hours of fasting (no food or drinks other than water).
- Postprandial Blood Sugar (PPBS): Measured 1-2 hours after eating a meal.
- Random Blood Sugar (RBS): Measured at any time of day, regardless of when you last ate.
- A1C Test (Glycated Hemoglobin): Measures average blood sugar levels over the past 2-3 months.
