What are the causes of habitual miscarriage? There are 6 causes

Habitual miscarriage is very common. There are many causes of this disease, including some objective factors, such as genetics and incompatibility of blood types between mother and fetus, and some physical defects, including congenital uterine malformations and relaxation of the internal cervical os, etc., which can induce the occurrence of habitual miscarriage and require early treatment.

In real life, habitual miscarriage is a common adverse symptom, which is extremely harmful to women's physical and mental health. Because habitual miscarriage will cause women to lose the opportunity to become mothers, it is easy to lead to worsening family conflicts and greatly affect the relationship between husband and wife. So, what are the causes of habitual miscarriage? Let's find out below.
Habitual miscarriage is just a symptom, but behind this manifestation, there are hidden causes of disease. The more common causes are as follows:
1. Genetic factors : When close relatives marry, one or both spouses may have chromosomal abnormalities. The closer the blood relationship between the couple, the more likely the chromosomal abnormality will be dominant in the next generation. Embryos with chromosomal abnormalities will not survive and will result in miscarriage.
2. Incompatibility of blood types between mother and fetus<br/>The most common is ABO blood type incompatibility. If the blood types of the mother and fetus are incompatible, the fetus obtains antigens from the father, enters the mother's body to produce antibodies, causing hemolysis, which can cause fetal death and lead to late miscarriage.
3. Luteal insufficiency <br/>Includes shortened corpus luteum lifespan and low corpus luteum secretory function, resulting in insufficient progesterone secretion and poor secretory response of the female endometrium, etc., which makes it difficult for the fertilized egg to implant, or the fertilized egg develops poorly after implantation, causing miscarriage.
4. Congenital uterine malformation <br/>In this case, for example, the patient has a bicornuate uterus or a uterus that is too narrow. In addition, there are also uterine cavity adhesions and uterine fibroids, etc. The occurrence of these diseases may induce habitual abortion.
5. Relaxation of the internal os of the cervix . Generally speaking, if a woman has habitual late miscarriage, it is usually because the internal os of the cervix is ​​too relaxed. Some women may be injured during surgery, while some women have congenital developmental abnormalities, which induces the expansion of the internal os of the cervix, leading to habitual miscarriage.
6. Multiple improper abortions <br/>Abortions are prone to infection due to improper implementation and post-operative anti-inflammatory treatment, which may cause endometritis, endometriosis, pelvic inflammatory disease, and intrauterine adhesions, leading to habitual miscarriage and infertility.
