What are the causes of miscarriage? There are 4 reasons

There are many reasons for miscarriage. When the pregnant woman has uterine malformation or cervical laceration, it will cause problems in the growth environment of the fetus and affect the growth of the fetus. Living in a harmful environment for a long time will also cause damage to the health of the fetus and affect the growth of the embryo.

Women need to do a good job of preventing miscarriage during pregnancy. Women's bodies are very fragile during pregnancy. Once there is an abnormality in the body, it is easy to cause miscarriage, which will not only affect the life and health of the fetus, but also cause infection or gynecological diseases in the mother. So what are the common causes of miscarriage?
1. Maternal factors <br/>There are many reasons for female miscarriage, among which maternal factors are the most common. Abnormal growth and development of the fetus due to uterine malformation or pelvic tumors, or severe cervical laceration due to cervical relaxation, can cause miscarriage. During pregnancy, women are prone to hypothyroidism, hormone disorders, luteal insufficiency or severe diabetes, which can cause miscarriage.
2. Environmental factors <br/>During pregnancy, women should try to live and work in a safe environment. There are many adverse external factors that affect reproductive function, which will have direct or indirect effects on the fetus. Excessive exposure to harmful chemicals during pregnancy can cause miscarriage. Therefore, the fetus needs to be protected in time, and pregnant women should try to work in a safe environment to avoid contact with some radioactive rays and harmful chemicals.
3. Genetic factors <br/>In the early stages of pregnancy, spontaneous abortion is mainly caused by chromosomal abnormalities in the embryo. Generally speaking, abnormal chromosome numbers are prone to abnormal chromosome structure. When chromosome breakage, deletion or translocation occurs in the fetus, most fetuses will experience miscarriage and rarely develop into normal fetuses.
IV. Immune factors <br/>Pregnancy is like allogeneic transplantation. There is a complex and special immunological relationship between the embryo and the mother. If there is immune incompatibility between the mother and the fetus, the mother will reject the embryo and cause miscarriage. The immune factors include fetal specific antigens, blood type antigens, and maternal cell immune regulation.
