What is the normal range for fasting blood glucose levels?

The normal range for fasting blood glucose levels is indeed 70-99 mg/dL. This range is established based on extensive clinical studies that have defined what is considered normal for healthy individuals without diabetes. Maintaining fasting blood glucose levels within this range is important because levels below 70 mg/dL can indicate hypoglycemia, while levels above 99 mg/dL might suggest impaired fasting glucose or diabetes.

The fasting state is typically defined as no caloric intake for at least 8 hours, allowing for a true measure of the body’s ability to manage glucose without the influence of food intake. This information is crucial for diagnosing and monitoring diabetes and other metabolic disorders. Understanding these values can help healthcare professionals provide appropriate screenings and interventions.
