Insulin Sensitivity Metric

Meaning

An insulin sensitivity metric is a quantitative clinical measure that assesses how effectively target cells, particularly those in muscle, fat, and liver tissue, respond to the signaling action of insulin to facilitate glucose uptake and utilization. A high metric indicates efficient glucose clearance from the bloodstream, representing robust metabolic health and flexibility. Conversely, a low metric suggests insulin resistance, which is a key precursor to metabolic syndrome and type 2 diabetes.
