宝宝有哪些常见的特殊的生理现象

新手爸妈由于没有经验,宝宝诞生后总要忙得手慌脚乱,宝宝稍有异常就很紧张。妇幼保健院医师提醒,其实有些宝宝的“异常”是特殊的生理现象,父母可不必太过担心,比如黄疸、体重下降、马牙、乳腺肿大、假月经、红斑和粟粒疹等。

当宝宝一有些异常时,家长们总是非常焦虑,但宝宝的这些异常中,有些却不属于病理状态,而是一种正常的生理现象,您了解过吗?那么,宝宝有哪些常见的特殊生理现象呢?广东省妇幼保健院林惠芳医师现在就带大家了解一下:

生理性黄疸

生理性体重下降

生后一周内,宝宝由于奶量摄入不足,加之水分丢失、胎粪排出,可出现暂时性体重下降或生理性体重下降,约在生后3~4天达最低点,下降范围为3 %~9%,以后逐渐回升,至出生后7~10日恢复到出生时的体重。如果下降体重超过10%或者至第10天还未恢复到出生时的体重时,则为病理状态,这是家 长需要带宝宝前往医院请专业的医师检查分析其原因。另外,出生后及时合理喂哺,可减轻或避免生理性体重下降的发生。

“马牙”
