A review of the causes of missed abortion

A missed abortion is a very sad thing for pregnant mothers. Sometimes there are no symptoms of missed abortion, no abdominal pain and no bleeding. During the pregnancy check-up, the mother is told that the embryo has stopped developing, but it is not expelled from the body like a natural abortion, but remains in the mother's uterus. So, what causes missed abortion? Let's take a look at the summary of the causes of missed abortion.

Missed abortion is also called overdue abortion or retained fetus. The embryo dies and remains in the uterine cavity, and the products of pregnancy are usually expelled within 1 to 2 months after the onset of symptoms. Therefore, it is stipulated that if the embryo has not been expelled naturally 2 months after the embryo stops developing, it is called missed abortion.

Causes of missed miscarriage:

1. Mental stress, this type of reasons include excessive tension,

2. Genetic defects, such as chromosomal abnormalities, chromosome mutations in one spouse, or incompatible blood types of the spouses;

3. Bad habits, such as excessive smoking, alcoholism, excessive coffee drinking, heroin, etc.

4. Environmental factors: Frequent exposure to chemicals such as arsenic, lead, formaldehyde, benzene, chloroprene, ethylene oxide, radiation, etc. can easily lead to missed abortion.

5. Reproductive organ abnormalities and uterine tumors.

6. Maternal factors: the mother has diseases, such as herpes simplex virus, cytomegalovirus, etc.;

7. Endocrine abnormalities, such as: uncontrolled severe diabetes, luteal insufficiency, hypothyroidism, etc.;

8. Abnormal immune function (pregnancy is similar to allogeneic transplantation. There is a complex and special immunological relationship between the embryo and the mother, which prevents the embryo from being rejected. If the mother and the child are not immune compatible, it may cause the mother to reject the embryo and cause miscarriage.

The above reasons are the causes of missed abortion during pregnancy. Once there is a phenomenon of missed abortion, you should go to the hospital for examination in time and cooperate with the treatment. During pregnancy, expectant mothers should also develop good work and rest habits and eat a reasonable diet to avoid the phenomenon of missed abortion.
