What is the reason for two miscarriages? It may be caused by these 5 reasons

If a woman has two unexpected miscarriages, she can be considered to have habitual miscarriage, which should be taken seriously. In addition to congenital genetic factors that cause habitual miscarriage, female immune system disorders, uterine anatomy abnormalities, endocrine disorders, and prothrombotic states can also cause habitual miscarriage.

After a woman becomes pregnant, she hopes that the fetus in her belly will grow up healthily, but in reality, many women will have miscarriages for no apparent reason, and even two pregnancies end in miscarriages. This situation can be called habitual miscarriage. So, what causes two miscarriages?
1. Immune disorder <br/>To put it simply, it is an abnormal situation in which the mother treats the fetus as a foreign body and launches an immune attack. Immune abortion may be caused by the inability of the woman's body to produce protective blocking antibodies for the fetus after pregnancy. In this case, the fetus will be attacked by the mother's immune cells, leading to abortion. In addition, the mother's own immune system disorder will produce antibodies against her own tissues and organs. These antibodies will destroy the fetal tissues, leading to the death of the fetus.
2. Uterine anatomical abnormalities <br/>Common conditions include uterine malformations, such as saddle-shaped uterus, unicornuate uterus, bicornuate uterus, uterine septate, etc. In addition, cervical insufficiency, uterine fibroids and intrauterine adhesions can also cause habitual abortion.
3. Endocrine disorders <br/>Endocrine disorders that lead to habitual abortion include internal medicine endocrine abnormalities and gynecological endocrine abnormalities. The former includes abnormal thyroid function and diabetes, while the latter includes polycystic ovary syndrome, hyperprolactinemia, luteal insufficiency, etc.
4. Genetic factors <br/>Habitual abortion is also related to genetic factors. If the chromosomes of the couple are abnormal, or the genes and chromosomes of the fetus are abnormal, habitual abortion may occur. Habitual abortion caused by genetic factors is not common. There is no effective way to solve it, and its recurrence rate is very high. The probability of successful pregnancy for such women is low, and diagnosis is very difficult and the cost is relatively high.
5. Prethrombotic state <br/>Some women have a disorder in the coagulation mechanism, which causes their blood to coagulate very quickly. This phenomenon is called prethrombotic state. When a woman becomes pregnant, blood clots may form in the placental blood vessels, causing the placenta's blood circulation to be blocked, causing the embryo to die due to ischemia.
