糖耐量受损(IGT)和空腹血糖受损(IFG)是正常葡萄糖稳态和糖尿病高血糖之间的中间阶段,流行病学资料显示二者的患病率不同,二者之间的重叠也较少[1],可能具有不同的病理生理机制。一些研究显示IGT主要存在胰岛素分泌功能缺陷[2],IFG以基础胰岛素抵抗为主[3],另外的研究结果则恰 Impaired glucose tolerance (IGT) and impaired fasting glucose (IFG) are intermediate stages of normal glucose homeostasis and diabetic hyperglycemia, and epidemiological data indicate a different prevalence of both and the overlap between the two Less [1] may have different pathophysiological mechanisms. Some studies have shown that IGT mainly has deficits in insulin secretion function [2], and IFG is based on basal insulin resistance [3]. The other findings just
