【摘要】 正常血糖的通用标准是空腹＜６．４ｍｍｏｌ／Ｌ，餐后２ｈ＜７．８ｍｍｏｌ／Ｌ，当空腹血浆血糖＞６．４ｍｍｏｌ／Ｌ而＜７．８ｍｍｏｌ／Ｌ，餐后２ｈ血糖≥７．８ｍｍｏｌ／Ｌ而＜１１．１ｍｍｏｌ／Ｌ时应怀疑有糖耐量异常而进行糖耐量试验，对糖耐量试验后仍为上述结果时，即诊断糖耐量异常。凡不够上述标准者便称为“糖耐量正常”，即在糖代谢方面为正常。但是，如果我们把这些所谓的正常血糖者中的餐后２ｈ血糖＞７．０ｍｍｏｌ／Ｌ，而＜７．８ｍｍｏｌ／Ｌ的患者作一分析，就可发现这些人的高血压、高血脂、肥胖的患病率以及餐后２ｈ的胰岛素浓度及胰岛素敏感性与糖耐量异常者相同，经统计学检验，无显著区别。这证明，餐后２ｈ血糖７．０～７．８ｍｍｏｌ／Ｌ不是正常血糖。餐后血糖的最佳临界点应以＜７．０ｍｍｏｌ／Ｌ为好。餐后２ｈ血糖＜７．０ｍｍｏｌ／Ｌ的患者有正常体重、正常的血压、正常的胰岛素敏感性。更多还原

【Abstract】 Patients whose level of postprandial blood glucose were more than 7.0 mmol/L,but less than 7.8 mmol/L, had the same prevalence of hypertension、dyslipidemia、 hyperinsulinemia and sensitivity of insulin as patients of IGT.Patients whose level of postprandial blood glucose were less than 7.0 mmol/L,had the same prevalence of hypertension、dyslipidemia、level of blood insulin and sensitivity of insulin as controls.These data suggest that normal level of postprandial serum glucose should be less than 7.0 mmol/L.更多还原
