Why does 3 months fetal stop

summary

Pregnancy is divided into three stages, early pregnancy, mid pregnancy and late pregnancy. Of course, the first trimester of pregnancy is three months ago. If fetal arrest is detected during the three months, let's take a look at why it happened.

Why does 3 months fetal stop

First: chromosomal abnormalities: whether sperm or egg, as long as the chromosome carrying genetic material is abnormal, even if a fertilized egg is formed, the embryo will not develop normally. Therefore, if there is a genetic history in the family, medical diagnosis and pre pregnancy physical examination should be carried out before pregnancy.

Second: virus infection: pregnant mother in early pregnancy infected with viruses such as rubella, cytomegalovirus, measles virus, hepatitis B virus, these viruses may be fatal to the fetus. Pregnant mother has chronic diseases: pregnant mother has serious chronic diseases, such as diabetes, hypertension, heart disease, viral hepatitis, etc. because of long-term medication, it has an impact on the life and health of the fetus.

Third: uterine abnormalities: the internal environment of the uterus and the overall environment of the uterus may have an impact on the embryo. Abortion caused by uterine defects accounted for about 10% - 15% of the clinical situation, leading to fetal arrest also accounted for about 10%. Placental factors: placental abruption, placenta previa, etc., lead to lack of oxygen supply to the placenta, so that the fetus died of hypoxia. Environmental factors: the pregnant mother irradiates the X-ray without knowing it and receives a large amount of radiation; or she comes into contact with toxic substances, including toxic chemicals and poor decoration materials, which can also lead to fetal arrest.
