糖尿病(DM)以Ⅱ型(非胰岛素依赖型)为主,约占95%,多见中老年。随着增龄,DM发生率也增加。人群中60岁时高血糖出现率可高达10%,80岁可高达20%,50岁以后,每10年空腹血糖在正常值基础上增加0.6mmol/L,餐后血糖增加0.5mmol/L,提示胰岛β细胞功能或胰岛素作用的敏感性均有所降低。高血糖对老年人的危害性不亚于年轻人,因为DM各种并发症可发生在老年人,并且可加速发展,促使过早衰老。 Diabetes (DM) to type Ⅱ (non-insulin-dependent), accounting for about 95%, more common in the elderly. With age, DM incidence also increased. 60-year-old population when the incidence of hyperglycemia can be as high as 10%, 80 years old can be as high as 20%, after 50 years of age, fasting blood glucose every 10 years increased 0.6mmol / L on a normal basis, postprandial blood glucose increased 0.5mmol / L, Tip islet β-cell function or insulin sensitivity were reduced. Hyperglycemia is as harmful to the elderly as younger people, as various complications of DM can occur in the elderly and can accelerate development, leading to premature aging.
