4.葉酸水平低

如果準媽媽體內(nèi)葉酸濃度過低，會增加6~12周胎停育的風險。因此，建議準備懷孕的未準媽媽從孕前3個月開始補充小劑量葉酸。

5.母體的內(nèi)分泌失調(diào)

受精卵著床及胚胎的發(fā)育依賴于母體復(fù)雜的內(nèi)分泌系統(tǒng)彼此協(xié)調(diào)，任何一個環(huán)節(jié)失常，都有可能會導(dǎo)致流產(chǎn)。在胚胎早期發(fā)育的時候，需要三個非常重要的激素，

一是雌激素，二是孕激素，三是人絨毛膜促性腺激素即HCG（早早孕試紙測試的指標），作為母體來講，如果自身分泌的激素不夠，就滿足不了胚胎發(fā)育的需要，這時就有極大的可能會造成胚胎的停育。其中最常見的是孕酮低，就影響受精卵的著床，導(dǎo)致早期的妊娠流產(chǎn)。還有如甲狀腺功能亢進或減退、糖尿病、高泌乳素血癥等，這些因素都會影響到胚胎的發(fā)育。

6.準媽媽生活的環(huán)境因素

早孕時期激素的變化，會導(dǎo)致母體對一些藥物和環(huán)境中有害物質(zhì)的吸收、分布和排泄都發(fā)生了較大的改變，在發(fā)育初期，胚胎對治療藥物和環(huán)境因素的影響非常敏感，在此時各種有害因素都可導(dǎo)致胚胎的損傷甚至于丟失。許多藥物和環(huán)境因素是引起早期胚胎死亡或胎兒畸形的重要因素。

為什么8-12周容易胎停

胎兒停止發(fā)育的癥狀有哪些呢？

1，孕婦的孕吐、乳房脹痛等早孕反應(yīng)會消失，因為胎兒停止發(fā)育后，雌孕激素分泌會減少，從而導(dǎo)致早孕反應(yīng)消失。

2，子宮停止增大，正常情況下，子宮的大小會隨著胎兒的生長而增大，如發(fā)現(xiàn)子宮停止增大，應(yīng)警惕胎兒停止發(fā)育。

3，陰道流血與下腹痛，這都是流產(chǎn)的先兆，當發(fā)現(xiàn)這種癥狀時，應(yīng)及早就醫(yī)檢查。

4，胎動減少，一般到了孕20周，孕婦可以自覺感到胎動，當發(fā)現(xiàn)胎動減少時，也應(yīng)及時就醫(yī)檢查胎兒情況。

小編的話：胎兒突然停止發(fā)育，想必媽媽們的心里一定是十分的著急害怕的，即擔心自己的身體是不是不適合孕育，更擔心再次懷孕會受其影響。其實，胎兒停止發(fā)育的原因，主要有以上的6個原因，孕婦的生活環(huán)境不適合孕育；母體的內(nèi)分泌失調(diào)；葉酸水平低；孕婦高齡不適合胎兒成長；胚胎質(zhì)量不好，染色體的原因；子宮環(huán)境的影響等。還有胎兒停止發(fā)育的4個癥狀表現(xiàn)，準媽媽都可以一并了解。
