前期阶段

Some patients do not have full-blown diabetes mellitus, but instead have impaired glucose tolerance, which is also called prediabetes. They have (elevations) in their blood glucose levels, but the levels are not as high as is seen in diabetes mellitus. These patients don't have the (microvascular) complications seen in true diabetes, but still have high risk of coronary artery disease.

有些患者还没有发展为糖尿病，只是葡萄糖耐量受损，这称为是糖尿病前期。他们的血糖水平升高，但不会像糖尿病患者那样高。这些患者没有真正的糖尿病微血管并发症，但仍有来自冠状动脉疾病的高风险。
