What is the normal fasting glucose level in the blood?

The normal fasting glucose level in the blood typically falls within the range of 70-110 mg/dL. This range is established by several health organizations and is widely accepted as the standard for assessing glucose metabolism in individuals who have not eaten for at least 8 hours. Fasting glucose levels are essential for the diagnosis and monitoring of diabetes, as elevated levels can indicate insulin resistance or a compromised ability to regulate blood sugar effectively.

Values below this range may suggest hypoglycemia, which can lead to symptoms like dizziness, confusion, or even loss of consciousness if severe, while levels above this range can raise concerns regarding glucose tolerance and the risk of developing diabetes. Regular monitoring of fasting glucose levels can help healthcare providers make informed decisions regarding dietary and lifestyle modifications or medical interventions needed to maintain glucose homeostasis.
