Insulin Sensitivity Markers

Meaning

Insulin Sensitivity Markers are quantifiable physiological and biochemical indicators used in clinical practice to assess the efficiency of a patient’s cells in responding to the hormone insulin. These markers, which include fasting glucose, fasting insulin, HbA1c, and the HOMA-IR index, provide critical insight into metabolic health and the risk of developing insulin resistance, type 2 diabetes, and related cardiometabolic diseases. Maintaining optimal sensitivity is a core strategy for longevity.
