What are the causes of miscarriage?

Abortion is a common obstetric disease. After a miscarriage, not only will the desired baby be lost, but the body of the pregnant mother will also be greatly harmed. In severe cases, it may even endanger her life. It is necessary for everyone to understand the causes of miscarriage. Everyone should take precautions in life to avoid misfortune caused by negligence. So, what are the causes of miscarriage?

1. Genetic Defects

It accounts for about 5% of early miscarriages, 30% of mid- and late-term pregnancy, and 3% of stillbirths. Genetic defects mainly refer to chromosome defects in one or both spouses, which cause abnormal embryos to form when the egg splits or the sperm and egg combine, thus leading to miscarriage. If this happens, it is recommended that both spouses should undergo further chromosome analysis, and the miscarriage embryo should also undergo chromosome analysis. In another case, the chromosome abnormality of the embryo is accidental, that is, it has nothing to do with the parents.

2. Abnormal uterine structure

This abnormality is one of the reasons for high miscarriage rates, including congenital double uterus, arcuate uterus, septate uterus or cervical weakness, or acquired cervical weakness, endometrial adhesions, uterine fibroids, adenomyoma, etc. General examination methods include ultrasound, traditional hysterosalpingography or magnetic resonance imaging.

3. Endocrine abnormalities

These include thyroid disease, diabetes, polycystic ovary, and excessive prolactin or luteal insufficiency. Clinically, they can be diagnosed by simply taking a blood test for hormones.

4. Inflammation and infection

If a woman has a filterable virus, bacteria, protozoa, parasite or fungal infection, she may easily suffer from miscarriage after pregnancy. Therefore, once the infection is confirmed, she must receive drug treatment.

5. Environmental factors

The environmental factors referred to here are common smoking, drinking and excessive coffee; as for environmental toxins, they include exposure to heavy metals (such as mercury, silver) and anesthetic gases.

Three or more consecutive miscarriages are considered habitual miscarriages. Habitual miscarriages seriously endanger women's health, are one of the main causes of infertility, and affect women's family happiness. However, habitual miscarriages can be easily confused with ordinary miscarriages. Therefore, if similar symptoms occur in daily life, you must go to a regular hospital for examination and treatment in time.
