5、论。总结（2） 尽管如此，对这些情况的处理已经有了很大改进。除了巨大儿，妊娠糖尿病母亲胎儿的围产期结局已经和非糖尿病母亲的相似了。总结（3） 有更多的证据表明，有妊娠糖尿病史的妇女得糖尿病(尤其是2型糖尿病)的危险性增加 在肥胖的妊娠糖尿病妇女中，即使是在产后数年，胰岛素抵抗仍然存在。KbNfQiUlXo#s%v(y0B3E6I9LdOgRjVmYp!t&w-z1C4G7JaMePhTkWnZr$u*x+A2E5H8KcNfQiUlXp#s%v)y0B3F6IaLdOgSjVmYq!t*w-z1D4G7JbMePhTkWoZr$u(x+A2E5H9KcNfRiUlXp#s&v)y0C3F6Ia
