目的探讨新诊断老年2型糖尿病患者血糖的波动特点。方法采用动态血糖监测系统对148例新诊断老年2型糖尿病患者和36例糖耐量正常的老年人进行(72±10)h血糖监测。结果新诊断的老年2型糖尿病患者血糖总体水平高、波动幅度大,可同时有餐前和凌晨低血糖。结论新诊断的老年2型糖尿病患者凌晨血糖接近正常、空腹血糖降低,进餐后血糖明显升高达高峰,个别患者同时有低血糖存在,血糖波动幅度大。
Objective To investigate the characteristics of blood glucose fluctuation in newly diagnosed type 2 diabetic elderly patients. METHODS: A total of 148 newly diagnosed elderly patients with type 2 diabetes mellitus and 36 elderly patients with impaired glucose tolerance were monitored for blood glucose (72 ± 10) h using a dynamic glucose monitoring system. Results The newly diagnosed type 2 diabetes in elderly patients with high overall level of blood glucose, volatility, both at the same time with low blood sugar before and after the meal. Conclusions The newly diagnosed type 2 diabetes mellitus patients get normal blood glucose at an early morning, the fasting blood glucose decreases, the blood glucose rises significantly after meal, and some patients have hypoglycemia at the same time.
