糖尿病是一种代谢性疾病,在治疗方面很大程度上需要病人配 合。除了饮食控制、按时吃药以外,血糖、尿糖监测也很重要。医生在调整治疗方案、指导用药和监测病情过程中都需要了解血糖的变化,但一次血糖值往往不能很好地反映病情变化。比如一个老年糖尿病患者平时血糖控制得很好,尿糖基本上都是阴性(无尿糖),只是最近一两天感冒、情绪不好,或者偶尔水果吃得稍微多一点儿,检查发现 Diabetes mellitus is a metabolic disease that requires patient cooperation to a large extent. In addition to diet control, medication on time, blood glucose, urine glucose monitoring is also important. Doctors need to understand the changes in blood glucose during the course of treatment, medication and monitoring. However, a blood glucose level often does not reflect the changes of the disease. For example, an elderly diabetes usually have good glycemic control, and urine is basically negative (no urine sugar), but the flu has not been good for one or two days in recent days or the fruit occasionally eats slightly more.
