What are the factors that cause miscarriage?

What are the factors that cause miscarriage? Nurturing life is a beautiful and wonderful thing, especially for some first-time mothers, the arrival of the baby is the beginning of their happy life. However, there are always some risk factors in life that cause pregnant women to have miscarriage. So, what are the factors that cause miscarriage? The following is a detailed introduction for everyone.

1. Genetic factors: In early spontaneous abortion, 50% to 60% of embryos have chromosomal abnormalities, most of which are abnormalities in chromosome number, followed by abnormalities in chromosome structure. Abnormalities in number include trisomy, triploidy and X monomer, etc.; structural abnormalities include chromosome breakage, inversion, deletion and translocation.

Most embryos with chromosomal abnormalities end in miscarriage. A very small number may continue to develop into a fetus, but some functional abnormalities or combined deformities may occur after birth. If miscarriage occurs, the product of pregnancy is sometimes just an empty gestational sac or a degenerated embryo.

2. Environmental factors: There are many adverse external factors that affect reproductive function, which can directly or indirectly cause damage to the embryo or fetus. Excessive exposure to certain harmful chemicals (such as arsenic, lead, benzene, formaldehyde, chloroprene, ethylene oxide, etc.) and physical factors (such as radiation, noise and high temperature, etc.) can cause miscarriage.

3. Maternal factors: Acute illness during pregnancy and high fever can cause uterine contraction and lead to miscarriage; bacterial toxins or viruses (herpes simplex virus, cytomegalovirus, etc.) enter the fetal blood circulation through the placenta, causing fetal death and miscarriage. In addition, severe anemia or heart failure in pregnant women can cause fetal hypoxia and may also cause miscarriage. If pregnant women suffer from chronic nephritis or hypertension, the placenta may infarct and cause miscarriage.

Expert tips: Expectant mothers should have a comprehensive understanding of the causes of miscarriage. Also, once a woman has a miscarriage, it will affect her physical health. Therefore, they should always pay attention to the occurrence of these problems in life. Of course, it is also very important to find out the causes and carry out symptomatic treatment.
