Is it high risk to get pregnant again after four miscarriages? What are the reasons for frequent miscarriages?

Nowadays, miscarriage is troubling more and more young pregnant women, especially in the early stages of pregnancy. So, is it high risk to get pregnant again after four miscarriages? What should you pay attention to when getting pregnant again?

What counts as miscarriage?

Abortion refers to the termination of pregnancy before 28 weeks of pregnancy and when the fetus weighs less than 1,000 grams. Abortion within 12 weeks of pregnancy is called early abortion; termination between 12 weeks and less than 28 weeks of pregnancy is called late abortion; termination of pregnancy by artificial factors such as machinery or drugs is called artificial abortion; abortion caused by natural factors (not caused by human intervention) is called spontaneous abortion. Abortion may be caused by the following factors, let's take a look.

Embryonic factors

Embryo chromosomal abnormalities are the main cause of miscarriage. Early miscarriage embryo examinations found that 50% to 60% had chromosomal abnormalities. If one of the spouses has chromosomal abnormalities, they can also be passed on to the offspring. In addition to inheritance factors, drugs and infections can also cause chromosomal abnormalities in embryos.

Maternal factors

Systemic diseases, such as infection, heart failure, chronic nephritis, severe anemia and malnutrition.

Endocrine abnormalities, such as hypothyroidism, severe diabetes, luteal insufficiency, etc.

Abnormal immune function, such as maternal-fetal blood type incompatibility, anti-sperm antibodies, etc.

Reproductive organ abnormalities, uterine malformations: including unicornuate uterus, bicornuate uterus, didelphys and uterine septate, etc. Among them, incomplete uterine septate is the most likely to cause miscarriage and premature birth.

Syndrome: The uterine cavity is reduced in size and the response to steroid hormones is reduced. Cervical insufficiency: It is prone to late miscarriage and premature birth, and is the main cause of miscarriage in mid-pregnancy.

Uterine fibroids: Submucosal fibroids and intramyostomy fibroids larger than 5 cm are associated with miscarriage.

Traumatic stimulation, such as surgery, impact, excessive sexual intercourse, excessive emotional tension, anxiety, etc.

Bad living habits

Some scholars have reported that women who smoke more than 14 cigarettes a day have a 2-fold increased risk of miscarriage compared to the control group. Alcoholism, excessive caffeine consumption, and environmental factors such as organic solvents and poisons have an impact.

Environmental factors

Excessive exposure to chemicals such as lead, formaldehyde, benzene, etc.

Five types of women should be careful about habitual miscarriage. Women with gynecological inflammation may have miscarriage if they become pregnant without treatment of vaginitis. For pregnant patients with vaginitis, the inflammatory virus will affect the health of the fetus and easily cause miscarriage. Women who have had multiple abortions and use abortion surgery to terminate pregnancy are likely to damage their reproductive function and cause habitual miscarriage. The increase in age of women who give birth has a great impact on their fertility. From the physiological law of women, it declines rapidly after the age of 35, and older pregnant women are prone to miscarriage. For women with luteal insufficiency, the corpus luteum secretes progesterone and estrogen, which plays an important role in maintaining female pregnancy and promoting embryonic development. If a woman's corpus luteum is incomplete, it will lead to habitual miscarriage. Women with loose internal cervical os Women with loose internal cervical os, coupled with a large range of motion, will lead to habitual miscarriage.
