1型糖尿病与2型糖尿病的主要区别在于

A．发病年龄不同
B．对胰岛素的敏感性不同
C．胰岛素基础水平与释放曲线不同
D．发生酮症酸中毒的倾向不同

答案

参考答案：C

解析：[考点] 1型糖尿病和2型糖尿病的鉴别
[分析] 1型糖尿病一般发病年龄较轻，对胰岛素敏感，易发生酮症酸中毒；2型糖尿病一般发病年龄较大，对胰岛素敏感性差，不易发生酮症酸中毒。但以上均不能作为鉴别l型糖尿病和2型糖尿病的主要依据，1型糖尿病也可在成年后发病，2型糖尿病治疗不及时或病变晚期时也可并发酮症酸中毒。两种糖尿病主要的区别在于胰岛素基础水平与释放曲线不同，1型糖尿病表现为基础胰岛素水平低下，胰岛素释放曲线平直，2型糖尿病基础胰岛素水平一般正常，胰岛素释放曲线表现为高峰延迟。
