Why do you miscarry yourself?

After a hard pregnancy, everyone hopes that the baby can be born healthy. However, during the pregnancy process, spontaneous abortion may occur. This is the most painful thing for pregnant women. To avoid it, we need to have a certain understanding of the causes of spontaneous abortion. So, why do you have a miscarriage? Let’s take a look at the reasons below.

1. Immune factors

At least half of miscarriages are related to the immune disorder of pregnant women, which leads to immune rejection of the embryo and ultimately causes miscarriage.

Before reproductive immunology examination methods were developed, the test results were almost always “no abnormalities found”, so no appropriate treatment was available. This antibody cannot be detected in women with immune abnormalities and habitual miscarriages. Due to the lack of this antibody, the pregnant mother cannot protect the embryo, which is rejected, leading to miscarriage.

2. Factors causing embryo abnormalities

Abnormal chromosome number or structure in the embryo will lead to abnormal embryonic development, which is the most common cause of habitual miscarriage. The environment, radiation, drugs, and natural mutations can all lead to genetic abnormalities in the embryo and cause miscarriage.

3. Environment and bad living habits

Staying up late, drinking, smoking, exposure to toxic substances, noise, vibration, high temperature environment, etc. can all cause damage to the fetus.

4. Multiple abortion surgeries

Starting sexual life too early after an abortion without taking any contraceptive measures may lead to an unexpected pregnancy and being forced to have another abortion, which may cause damage to the endometrium and lead to habitual abortion.

5. Abnormal semen of the male

The male's semen volume, sperm concentration, percentage of grade A/B sperm, percentage of abnormal sperm, etc. are all closely related to the occurrence of habitual abortion.

6. Luteal insufficiency

Symptoms of luteal insufficiency before pregnancy may include shortened menstrual cycles, premenstrual spotting, and normal or slightly heavier menstrual flow. These symptoms are common and usually go unnoticed until they lead to recurrent miscarriage, which is sometimes diagnosed by measurement of basal body temperature and plasma hormone levels or by curettage.

7. Habitual abortion caused by infection

The most concerning infectious factor is TORRCH syndrome, which is infection with pathogens such as rubella virus, cytomegalovirus, herpes simplex virus or Toxoplasma gondii during pregnancy. These microorganisms can infect the embryo through the placenta and cause ligand developmental malformations, miscarriage or stillbirth. Another common mycoplasma infection also increases the risk of spontaneous abortion.

8. Uterine and cervical lesions

Congenital uterine malformations, intrauterine adhesions, intrauterine polyps, uterine fibroids, adenomyosis, etc. Habitual miscarriage caused by cervical lesions is very common, the main reasons are cervical incompetence and short cervical canal.

9. Internal medicine diseases

Endocrine disorders such as kidney disease, heart disease, hypothyroidism, hyperthyroidism, etc. can also cause miscarriage.
