What Are Normal Blood Sugar Levels? The Complete Chart for Adults by Age
Understanding normal blood sugar levels is crucial for maintaining overall health and preventing serious conditions like diabetes. But what's considered "normal" can vary based on age, individual factors, and whether you've eaten recently. This comprehensive guide provides a detailed breakdown of healthy blood sugar ranges for adults, categorized by age, and offers insights into managing your glucose levels effectively.
Why Monitoring Blood Sugar Matters
Regular blood sugar monitoring helps you and your healthcare provider identify potential issues early. Uncontrolled high blood sugar (hyperglycemia) can lead to complications like heart disease, kidney damage, nerve damage, and vision problems. Conversely, chronically low blood sugar (hypoglycemia) can cause seizures, loss of consciousness, and, in severe cases, even death. Therefore, staying within the normal blood sugar range is paramount.
