It is well-known that type 2 diabetes is preceded by a long prediabetic state characterized by mild elevation of fasting and/or postprandial glucose levels. However, previous studies on the relative contributions of insulin secretory defects and insulin resistance in the development of impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) have yielded contradictory results [1-4]. Inconsistencies across the studies have been explained by differences in study populations, study designs and methods to assess insulin resistance and insulin secretion. \u0000 \u0000The nature of progressive β-cell failure occurring as normal glucose-tolerant (NGT) individuals progress to type 2 diabetes is incompletely understood. Moreover, the precise level of hyperglycemia at which β-cell function begins to decline has not yet been established. Research has shown that during the natural development of type 2 diabetes, fasting plasma insulin increases and then decreases as insulin resistance develops, displaying the typical inverted U-shaped curve that has been referred to as \"Starling's curve of the pancreas\" [5]. Earlier studies reported that the plasma insulin response to glucose rises progressively until the fasting plasma glucose reaches 120 to 140 mg/dL, and further increases in fasting glucose levels are associated with a progressive decline in insulin secretion [6]. \u0000 \u0000To date, several studies have examined insulin secretion as a function of glucose concentrations in various populations [7-11]. Some studies have shown that individuals with IFG and/or IGT have a pronounced defect in early insulin secretion [7,12]. Other studies demonstrated that the decline in β-cell function occurs at an earlier stage that is considered normal according to current diagnostic criteria [8,10,11]. Only limited studies have assessed early insulin secretion based on dynamic tests in Koreans [13-16]. In the studies that do exist, the numbers of participants were small; no studies have yet assessed the changes in insulin secretion in relation to the changes in fasting and postprandial glucose levels ranging from NGT to IGT and type 2 diabetes. \u0000 \u0000In this issue, Rhee et al. [17] analyzed early-phase insulin secretion during oral glucose tolerance tests (OGTT) in relation to plasma glucose levels ranging from normal to the diabetic range of hyperglycemia in 873 Korean participants. The key finding of this report was that the decline of early-phase insulin secretion according to the increase of plasma glucose concentration begins early and progresses rapidly during the period generally designated as \"normal.\" According to their results, early-phase insulin secretion was reduced to <50% of the control group in participants with fasting glucose levels of 100 mg/dL, postload 2-hour glucose of 145 mg/dL, and HbA1c of 5.8%.
