Classification of Diabetes Mellitus(WHO 1998) ype l insulin dependent diabetes mellitus, IDDM ype ll non-insulin dependent diabetes mellitus, NIDDM a Others: secondary diabetes
Classification of Diabetes Mellitus (WHO 1998) ◼ TypeⅠ: insulin dependent diabetes mellitus，IDDM ◼ TypeⅡ: non-insulin dependent diabetes mellitus，NIDDM ◼ Others： secondary diabetes
Diabetes Mellitus Type I Diabetes a Type 2 Diabetes cells that produce insulin are blood glucose levels rise due to destroved 1) Lack of insulin results in insulin dependence production commonly detected before 30 2)Insufficient insulin action(resistant cells) commonly detected after 40 effects >90% Pancrea eventually leads to B-cell failure (resulting in insulin dependence) killed to lymph nodes Gestational Diabetes(妊娠糖尿病) 3-5% of pregnant women in the US Lymph node develop gestational diabetes
Diabetes Mellitus ◼ Type 1 Diabetes - cells that produce insulin are destroyed - results in insulin dependence - commonly detected before 30 ◼ Type 2 Diabetes - blood glucose levels rise due to 1) Lack of insulin production 2) Insufficient insulin action (resistant cells) - commonly detected after 40 - effects > 90% - eventually leads to β-cell failure (resulting in insulin dependence) Gestational Diabetes （妊娠糖尿病） 3-5% of pregnant women in the US develop gestational diabetes
