2型糖尿病发病是因为胰岛B细胞的损伤和破坏,导致胰岛素分泌不足和胰岛素抵抗;发病开始可以使用降糖药物控制血糖,患者随着病情发展,胰岛分泌功能越来越差,使用常规降糖药物,常导致血糖波动幅度较大。动态血糖监测系统(continuous glucose monitoring system,CGMS)可72 h持续监测血糖,能更好地为患者提供血糖波动信息;持续胰岛 Type 2 diabetes is due to the damage and destruction of islet B cells, leading to insufficient insulin secretion and insulin resistance; onset can be used to control blood sugar hypoglycemic agents, patients with the progression of the disease, the islet secretion worse and worse, the use of conventional hypoglycemic Drugs, often lead to greater fluctuations in blood sugar. Continuous glucose monitoring system (CGMS) can continuously monitor blood glucose for 72 hours, which can better provide blood glucose fluctuation information to patients. Continuous islet
