What is the normal range for fasting blood glucose levels?

The normal range for fasting blood glucose levels is between 70 to 100 mg/dL. This range is established based on extensive research and guidelines from health organizations, indicating ideal metabolic functioning and glucose homeostasis in healthy individuals. A fasting glucose level below this range (50 to 70 mg/dL) suggests hypoglycemia, which can lead to symptoms such as dizziness, confusion, and fainting. Conversely, values above 100 mg/dL indicate impaired fasting glucose, and levels of 126 mg/dL or higher suggest diabetes, necessitating further evaluation and management. Thus, maintaining a fasting blood glucose level within the 70 to 100 mg/dL range is vital for preventing metabolic disorders and ensuring overall health.
