糖尿病前期(Impaired glucose regulation,IGR)是指血糖水平处于正常与糖尿病之间的时期,包括空腹血糖受损(Impaired free glucose,IFG)和糖耐量受损(Impaired glucose tolerance,IGT)以及两者合并存在三种状态。IGR人群在短期内发展为2型糖尿病(DM)的绝对危险比一般人群高3~10倍,IGR人群的心血管疾病危险明显增加,以IGT更为显著,其中部分已存在特征性血管改 Impaired glucose regulation (IGR) refers to the period between normal glucose levels and diabetes mellitus, including Impaired free glucose (IFG) and impaired glucose tolerance (IGT) and their combination There are three states. The absolute risk of developing type 2 diabetes mellitus (DM) in IGR is 3 to 10 times higher than that in the general population. The risk of cardiovascular disease is significantly increased in IGR population, and the more obvious is IGT, some of which have characteristic vascular changes
