What is the normal range for fasting blood sugar levels?

The normal range for fasting blood sugar levels is 70-100 mg/dL. This range is critical for assessing overall metabolic health and is used as a standard reference when identifying potential blood sugar abnormalities. A fasting blood sugar level within this range indicates that the body's insulin response is functioning adequately and that glucose is being processed effectively.

Fasting blood sugar levels below 70 mg/dL can indicate hypoglycemia, which is a state of low blood sugar that may result in various symptoms or complications. Levels above 100 mg/dL suggest a state of prediabetes and could indicate the body's difficulty in managing blood glucose effectively, which can eventually lead to type 2 diabetes if not addressed. Understanding these ranges is essential for proper monitoring and management of individuals’ health conditions related to blood sugar.
