What fasting glucose range indicates prediabetes?

A fasting glucose range of 100-125 mg/dL is indicative of prediabetes, as it falls within the established criteria set by health organizations like the American Diabetes Association. This threshold reflects an intermediate state where blood glucose levels are higher than what is considered normal but not high enough to meet the criteria for diabetes.

Fasting glucose levels below 100 mg/dL are classified as normal, indicating that the body's insulin response and glucose metabolism are functioning well. A fasting level of 126 mg/dL or higher is diagnostic for diabetes, marking a significant concern for impaired glucose metabolism. The range of 90-110 mg/dL includes normal levels but does not capture the specific range associate with prediabetes.

Understanding these categories is vital in clinical practice, as identifying individuals with prediabetes allows for early intervention strategies to prevent the progression to type 2 diabetes.
