What is the standard range for blood glucose levels?

The standard range for blood glucose levels in a healthy adult is considered to be between 70 and 100 mg/dL when measured in a fasting state. This range is widely accepted by medical organizations and reflects normal metabolic function. Blood glucose levels below this range may indicate hypoglycemia, which can lead to various symptoms like dizziness, confusion, and even loss of consciousness if severe. Conversely, levels above this range can signify hyperglycemia, a condition that may indicate diabetes or other metabolic disorders.

Maintaining blood glucose within this range is crucial for overall health. It ensures that the body has adequate energy while avoiding the complications associated with both low and high glucose levels. In clinical settings, this information is especially important for the management of conditions such as diabetes, where strict control of blood glucose levels can prevent complications.
