孕妇妊娠期间常会出现恶心和呕吐现象,但某些孕妇的剧烈呕吐往往需要送医院治疗。一项最新研究显示,这种被称为妊娠剧吐的症状会由妈妈传给女儿,它很可能具有家族遗传性。新一期《英国医学杂志》刊登报告说,挪威研究人员分析了该国过去几十年里230万份出生记录,以及相应孕妇的健康数据,结果发现,如果母亲怀孕期间出现妊娠剧吐症状,女儿怀孕时出现该症状的可能性是其他人的3倍左右。 Nausea and vomiting often occur during pregnancy in pregnant women, but severe vomiting in some pregnant women often requires hospital treatment. A new study shows that this symptom known as hyperemesis gravidarum is passed from mother to daughter and is likely to be familially inherited. The new issue of the British Medical Journal reports that Norwegian researchers analyzed 2.3 million birth records in the country over the past few decades and the health status of their corresponding pregnant women and found that if the mother experienced gestational hyperemesis during pregnancy, The likelihood of developing this symptom when the daughter is pregnant is about three times that of the others.
