一、调节妊娠糖代谢的内分泌背景参与糖代谢的内分泌物质极多。对血糖下降唯一起作用的是胰岛素,而有许多物质能使血糖上升。其中也有胎盘(绒毛)产生的激素。妊娠中调节糖代谢的激素主要有: 1.胰岛素胰岛素能促进各种组织的糖利用。葡萄糖能刺激胰岛素的分泌,促进肝糖原的合成,诱发肝脏糖利用酶系活动,抑制糖新生酶系,从而抑制糖的分解。关于妊娠中胰岛素分泌,目前多数见解是一致的。从妊娠末期胰岛素呈明显的特异性变化来看,空腹时血中胰岛素值与非妊娠时无大差异,但不论用那一种糖负荷方法,在给葡萄糖及血中胰岛素值比非妊娠时的分泌显著增多。著者曾观察了无糖尿病素质的孕妇,从妊娠28周到38周自身于75g葡萄糖耐量试验(GTT),平均值随着妊娠的进展量增多,负荷后1小时的值显示急骤亢进。从妊娠35周
First, regulate the endocrine of glucose metabolism in pregnancy background involved in glucose metabolism of endocrine substances very much. Insulin is the only factor that contributes to the decline in blood sugar, and there are many substances that make blood sugar rise. There are also hormones produced by the placenta (villi). Pregnancy regulation of glucose metabolism are: 1. Insulin Insulin can promote the utilization of various tissues of sugar. Glucose can stimulate the secretion of insulin, promote the synthesis of hepatic glycogen, induce the activities of the liver sugar enzyme, inhibit the enzyme system of sugar, thus inhibiting the decomposition of sugar. With regard to insulin secretion during pregnancy, most of the current opinions are consistent. Insulin from the end of pregnancy were significantly specific changes in point of view, fasting blood insulin value and no significant difference in non-pregnancy, but no matter with which kind of sugar load method, in glucose and blood insulin value than non-pregnancy Secretion increased significantly. The authors have looked at non-diabetic pregnant women with their 75g glucose tolerance test (GTT) from 28 weeks to 38 weeks of gestation. The mean increases with the amount of pregnancy, and one hour after loading shows an acute hyperthyroidism. 35 weeks from pregnancy
