What Are Normal Blood Sugar Levels by Age?
Understanding normal blood sugar levels is crucial for maintaining good health, regardless of age. This article provides a comprehensive overview of what constitutes healthy blood sugar ranges at different life stages, factors that can influence these levels, and when to seek medical advice.
Why Blood Sugar Levels Matter
Blood sugar levels, or glucose levels, refer to the concentration of glucose in your blood. Glucose is your body's primary source of energy, derived from the food you eat. Maintaining stable blood sugar levels is essential for optimal bodily functions. When glucose levels are consistently too high (hyperglycemia) or too low (hypoglycemia), it can lead to various health complications.
