What causes habitual miscarriage? 9 reasons to avoid

There are many causes of habitual miscarriage, including immune factors, embryo abnormalities, environmental and bad living habits, multiple abortions, multiple abortions, luteal insufficiency, infection-induced habitual miscarriage, uterine and cervical lesions and other factors.

A small negligence during pregnancy may lead to miscarriage, which will lead to all previous efforts being wasted. If the number of miscarriages is too many, it will form habitual miscarriage. Within 28 weeks of pregnancy, when the fetus stops developing and the fetal weight does not reach 500 grams, it is called spontaneous miscarriage. When spontaneous miscarriage occurs 2-3 times or more in a row, and each miscarriage is concentrated in the same month of pregnancy, it is called habitual miscarriage. So, what are the causes?
1. Immune factors <br/>At least half of miscarriages are related to the immune disorder of the pregnant mother, which leads to immune rejection of the embryo and ultimately causes miscarriage.
Before the reproductive immune examination method was developed, the examination results were almost always "no abnormality found", so no corresponding treatment was given. In women with immune abnormalities and habitual miscarriage, this antibody cannot be detected. Without this antibody, the pregnant mother cannot protect the embryo and it is rejected, which leads to miscarriage.
2. Embryo abnormality factors <br/>Abnormal chromosome number or structure of the embryo will lead to abnormal embryo development, which is the most common cause of habitual miscarriage. Environment, radiation, drugs, and natural mutations can all lead to embryo genetic abnormalities and cause miscarriage.
3. Environment and bad living habits <br/>Staying up late, drinking, smoking, exposure to toxic substances, noise, vibration, high temperature environment, etc. can all cause damage to the embryo.
4. Multiple abortions <br/>Resuming sexual life too early after abortion without any contraceptive measures, and being forced to choose artificial abortion due to unexpected pregnancy, which causes damage to the endometrium and habitual abortion.
5. Abnormal semen of the male <br/>The male's semen volume, sperm concentration, percentage of A/B grade sperm, percentage of abnormal sperm, etc. are all closely related to the occurrence of habitual abortion.
6. Luteal insufficiency <br/>Pre-pregnancy luteal insufficiency symptoms include shortened menstrual cycles, premenstrual spotting, and normal or slightly heavier menstrual flow. These symptoms are common and usually go unnoticed before they lead to habitual miscarriage. Sometimes basal body temperature measurement and plasma hormone level measurement or curettage are required for diagnosis.
7. Habitual abortion caused by infection <br/>The most concerned infectious factor is TORCH syndrome. During pregnancy, if a woman is infected with pathogens such as rubella virus, cytomegalovirus, herpes simplex virus or Toxoplasma, these microorganisms can infect the embryo through the placenta, causing ligand developmental malformation, miscarriage or stillbirth. Another common mycoplasma infection also increases the risk of spontaneous abortion.
8. Uterine and cervical lesions <br/>Congenital uterine malformations, intrauterine adhesions, intrauterine polyps, uterine fibroids, adenomyosis, etc. Cervical lesions are also common in causing habitual abortions, and the main reasons are cervical insufficiency and short cervical canal.
9. Internal medicine diseases <br/>Endocrine disorders such as kidney disease, heart disease, hypothyroidism, hyperthyroidism, etc. can also cause miscarriage.
If your body encounters these problems, do not relax your vigilance and go to a regular hospital for a physical examination in time to avoid habitual miscarriage. Abortion is very harmful to the body of women. Pregnancy is a complicated process for women. Any problem in any link will affect the fetus and the female body. Therefore, women should take care of their bodies to provide a healthy environment for their babies.
