妇女怀孕后,随着胎儿的生长发育以及孕妇自身为适应胎儿的生长,会发生一系列代谢性变化,最明显的就是体重增加,妊娠足月时体重一般可增加12.5公斤左右。而许多孕妇认为,体重增加越多,表明胎儿越健康。其实这种认识并不完全正确。专家认为,若孕妇体重增加过多造成孕期肥胖,这对孕妇分娩带来困难,容易造成难产,这对胎儿和产妇自身健康都会造成很大危害。
After the woman is pregnant, as the fetus grows and develops, as well as the pregnant woman themselves adapt to the growth of the fetus, a series of metabolic changes occur. The most obvious is the weight gain. The weight of the pregnant women can increase by about 12.5 kg at the full term. Many pregnant women believe that the more weight gain, the more healthy the fetus. In fact, this understanding is not entirely correct. Experts believe that if too much weight gain pregnant women cause obesity during pregnancy, which brings difficulties to the delivery of pregnant women, likely to cause dystocia, which the fetus and maternal health will cause great harm.
