害喜或意味着宝宝健康

2017-12-10 10:54:10   新华网

英国一项研究结果或许能让害喜的准妈妈们找到些许安慰:孕吐可能意味着腹中胎儿得到了充分的营养。

雷丁大学研究人员在最新一期《分子内分泌学期刊》上刊文说,他们去年起调查了800名孕妇生育资料,发现有过流产史的孕妇如果出现恶心或孕吐,宝宝平安出生的几率会提高。他们进一步研究发现,孕吐由体内一种激肽引起,但这一激素同时能确保胎盘内血流正常,保证胎儿获得充足供氧和营养物质。

数据显示,八成以上孕妇怀孕头12周会恶心,半数会孕吐,但这些症状在孕16周至20周会消失。孕吐通常对胎儿没有影响,无需医疗干预,孕妇多休息、多饮水、少吃多餐即可。只有极少数孕妇呕吐严重,医学上称为妊娠剧吐,需要住院输液,以确保营养供应。(王鑫方)【新华社微特稿】
