Will threatened abortion lead to fetal malformation?

Pregnancy preservation for threatened abortion usually does not lead to fetal malformation, but it depends on the specific cause, treatment method and the use of pregnancy preservation drugs. In order to ensure the health of the fetus, we should actively find the cause of threatened abortion and choose appropriate treatment measures, such as using reasonable drugs, improving lifestyle and regular prenatal examinations.

1 Analysis of the causes of threatened abortion

Threatened abortion may be caused by a variety of factors including genetics, environment, physiology and pathology.

Genetic factors: Fetal chromosomal abnormalities are the most common cause, accounting for 50%-60% of threatened abortions. This is usually a natural selection mechanism and has little to do with pregnancy preservation treatment.

Environmental factors: including pregnant women's exposure to harmful substances such as smoking, drinking, chemicals, and infection with viruses such as rubella virus, which may affect the development of the embryo.

Physiological factors: Insufficient progesterone in pregnant women, abnormal uterine structure such as thin endometrium or congenital malformations may cause the embryo to fail to implant or develop smoothly.

Pathological factors: Pregnancy complicated by diabetes, abnormal thyroid function, severe anemia and other diseases, as well as pregnancy at an advanced age of over 35 years old are also important causes of threatened abortion.

2 Treatment methods for threatened abortion and whether it may cause deformity

The scientific nature of fetal preservation and the rationality of treatment will directly affect the health of the fetus. The following three measures for fetal preservation should be understood in particular:

Drugs used: Commonly used drugs are progesterone, low molecular weight heparin, etc. Progesterone is mainly used to correct progesterone deficiency, but it must be used in moderation according to the doctor's advice. Abuse of large doses of drugs may interfere with fetal hormone levels.

Bed rest: For some pregnant women with active uterine contractions or abdominal pain, reducing the amount of activity can reduce the risk of miscarriage. However, long-term bed rest may lead to thrombosis, so you should pay attention to regular limb movement.

Medical intervention: If the cervix is ​​incompetent or too short, miscarriage can be avoided through cervical cerclage. This operation has little effect on the fetus, but it needs to be performed by a professional doctor.

3. Fetal health assessment after threatened abortion

Even if the pregnancy is successfully preserved, it is necessary to strengthen the monitoring of embryonic development during pregnancy to screen for the risk of malformation. Pregnant women can undergo the following examinations during the second trimester:

Down syndrome screening: A preliminary assessment of the fetus's possibility of congenital chromosomal abnormalities is performed through serological tests.

Four-dimensional color ultrasound: Check whether the fetal organ development is normal and ensure there are no structural malformations.

Non-invasive DNA or amniocentesis: Further detection of fetal chromosomal abnormalities for high-risk pregnant women.

The key to preserving the fetus during threatened abortion is scientific treatment and regular check-ups. From preserving the fetus to the entire pregnancy, it is imperative to be carried out under the guidance of a professional doctor to maximize the health of the fetus. If there are any concerns, consult an obstetrician and gynecologist and do not adjust or stop taking the medication on your own.
