妊娠期糖尿病是高危妊娠之一,可引起多种不良妊娠结局。对孕妇、胎儿和新生儿的影响与妊娠合并糖尿病一样,易造成羊水过多、妊娠高血压综合征、巨大儿或胎儿生长受限、胎儿宫内缺氧甚至死胎等。胎盘是母-婴间物质交换的重要器官,它的病理改变与围产儿的结局有着密切的关系。 Gestational diabetes is one of the most dangerous pregnancies and can cause many adverse pregnancy outcomes. The impact on pregnant women, fetuses and newborns and pregnancy with diabetes, can easily lead to polyhydramnios, pregnancy-induced hypertension syndrome, macrosomia or fetal growth restriction, fetal hypoxia or stillbirth and so on. Placenta is an important organ exchange between mother and baby, and its pathological changes are closely related to the outcome of perinatal children.
