Low insulin-stimulated glucose disposal (M) and low acute insulin secretory response (AIR) are independent and additive predictors of the progression from normal glucose tolerance (NGT) to impaired glucose tolerance (IGT) and from IGT to type 2 diabetes.

If you have normal or pre-diabetic blood sugar, your body's ability to use insulin (sensitivity) and its ability to release insulin quickly (secretion) are the two main levers determining if you develop diabetes. Both matter equally at every stage. Monitoring these metrics can help identify high-risk individuals for early intervention.
