Under what circumstances is habitual miscarriage likely to occur?

It is a very long process for adult women to go from the early stages of pregnancy to successful delivery. During pregnancy, some women are prone to symptoms of miscarriage in the first three months of pregnancy. Abortion also causes certain harm to women's bodies. Any woman who has had a miscarriage once is likely to have habitual miscarriage again when she becomes pregnant again. Next, let’s take a detailed look at the circumstances under which habitual miscarriage is likely to occur and what precautions to take.

1. Incomplete embryonic development: Abnormal fertilized eggs are the main cause of early miscarriage. About 80% of miscarriages in the first two months of pregnancy are due to some defects in sperm and eggs, which causes the embryo to develop to a certain extent and then terminate. Therefore, the original embryonic tissue cannot be seen in the discharge of this type of miscarriage.

2. Endocrine dysfunction: The fertilized egg can only implant on the uterine wall and grow and develop into a fetus under the action of progesterone. When the body does not secrete enough progesterone, the uterine decidua will develop poorly, thus affecting the development of the fertilized egg and easily causing miscarriage. If the amount of prostaglandins increases, it will cause frequent contractions of the uterine muscles and may also lead to miscarriage. Reduced thyroid function can cause cell oxidation disorders, thereby affecting the growth and development of the embryo and causing miscarriage.

3. Reproductive organ diseases: uterine malformations such as bicornuate uterus, septate uterus, and uterine hypoplasia. Pelvic tumors, especially submucosal fibroids, can affect the growth and development of the fetus and cause miscarriage. Relaxation of the internal os of the uterus or deep laceration of the cervix can cause premature rupture of the membranes and lead to late miscarriage.

4. Systemic diseases of pregnant women: Pregnant women suffer from acute infectious diseases such as influenza, typhoid fever, pneumonia, etc. Bacterial toxins or viruses enter the fetus through the placenta, causing fetal poisoning and death. High fever can promote uterine contractions and cause miscarriage. Pregnant women suffering from chronic diseases such as severe anemia, heart failure, chronic nephritis and hypertension may suffer fetal disability and miscarriage due to placental infarction and intrauterine hypoxia. Malnutrition of pregnant women, especially vitamin deficiency, as well as mercury, lead and alcohol poisoning can cause miscarriage.

5. Trauma: The abdomen of a pregnant woman is hit or squeezed by external force, or she falls or participates in heavy physical labor or strenuous sports; abdominal surgery such as appendicitis or ovarian cyst surgery can cause uterine contraction and miscarriage.

The above is a detailed introduction to the circumstances under which habitual miscarriage is likely to occur and the precautions that women should take when experiencing habitual miscarriage. I believe this is useful for some women who are in the early stages of pregnancy or are preparing to become pregnant. We have a better understanding of habitual miscarriage. It is recommended that women pay more attention to their living and eating habits in the first three months of pregnancy. Do not eat raw, cold, or foods that may cause uterine contractions.
