What is the normal range for blood glucose levels (BGL) in adults?

The normal range for blood glucose levels (BGL) in adults is typically between 60 to 100 mg/dL when measured in a fasting state. This range reflects the body's ability to maintain glucose homeostasis, ensuring that sufficient energy is available for cellular functions while preventing the adverse effects associated with both low and high blood sugar levels.

Maintaining blood glucose within this range is critical, as levels below 60 mg/dL can lead to hypoglycemia, which can cause symptoms like confusion, weakness, and, in severe cases, loss of consciousness. Conversely, levels above 100 mg/dL, particularly when persistent, can indicate hyperglycemia and may be a sign of diabetes or other metabolic disorders. Thus, the chosen answer aligns with established guidelines for normal blood glucose levels, which is essential for both clinical assessment and monitoring of patients.
