早孕反应严重了会导致流产吗?Is early pregnancy reaction serious can cause miscarriage?

早孕反应包括头晕、疲乏、嗜睡、食欲不振、偏食、厌恶油腻、恶心、呕吐等。反应轻重因人而异，多数人在孕6周前后出现，8～10周达到高峰，孕12周左右自行消失。少数孕妇早孕反应严重，频繁恶心呕吐，不能进食，以致发生体液失衡及新陈代谢障碍，影响胎儿生长发育，导致流产甚至危及孕妇生命。

Early pregnancy reactions include dizziness, fatigue, drowsiness, loss of appetite, partial eating, aversion to greasy, nausea, and vomiting. The degree of response varies from person to person. Most people appear around 6 weeks of pregnancy, peak 8 to 10 weeks, and disappear around 12 weeks of pregnancy. A small number of pregnant women have severe early pregnancies, frequent nausea and vomiting, and can not eat, resulting in imbalance of body fluids and metabolic disorders, affecting fetal growth and development, leading to miscarriage and even endangering the life of pregnant women.
