What causes threatened abortion? Is there any way to cure it?

Threatened abortion may be caused by genetics, environment, endocrine disorders or infection, and the resulting fetal growth retardation requires targeted treatment based on the specific cause, including lifestyle adjustments, drug interventions or surgical treatments. Pre-pregnancy examinations and early pregnancy care are particularly important.

1. Genetic factors

Chromosomal abnormalities in the embryo are one of the main causes of threatened miscarriage and fetal growth retardation, and are common in cases of gene mutation or chromosomal abnormalities. For couples with genetic factors such as balanced chromosomal translocation, the embryo may not develop normally and eventually stop growing. The solution is that the couple can undergo a chromosome test before pregnancy. If problems are found, they can choose preimplantation genetic diagnosis (PGS)/PGD technology to screen healthy embryos, thereby reducing the risk of fetal growth retardation.

2. Environmental factors

Bad living habits or exposure to harmful substances during pregnancy will increase the risk of fetal growth retardation. Long-term exposure to high radiation, smoking and drinking, and exposure to harmful chemicals will affect the growth and development of the embryo. It is recommended to maintain a healthy lifestyle during pregnancy preparation and pregnancy, avoid environmental pollution, stay away from tobacco and alcohol, have regular prenatal checkups, and intervene promptly if abnormalities are found.

3. Physiological and endocrine factors

Endocrine disorders such as luteal insufficiency, thyroid dysfunction, and polycystic ovary syndrome can lead to insufficient nutrition and hormone supply to the embryo, affecting embryo implantation or growth. Abnormal uterine structure such as uterine cavity adhesions, uterine malformations, and uterine fibroids can also lead to fetal growth retardation. For endocrine problems, doctors can improve physiological conditions by supplementing progesterone, controlling thyroid function, or performing hormone therapy; uterine problems are usually corrected through minimally invasive surgery.

4. Infection factors

Infection with bacteria or viruses such as toxoplasmosis, rubella virus, and cytomegalovirus during pregnancy may directly affect the normal development of the embryo or even cause embryonic death. In this case, pathogen screening is required, and targeted drug treatment is used after the source of infection is identified. A health assessment is also required after treatment to ensure that there is no residual risk before preparing for pregnancy.

5. Pathological causes and other external factors

Some chronic diseases, such as hypertension, diabetes, and autoimmune diseases such as antiphospholipid syndrome, can interfere with the stability of the blood and oxygen supply to the embryo and affect the development process. These diseases need to be controlled through pre-pregnancy adjustments, and during pregnancy, you need to work closely with your doctor, take medication on time, or take measures to protect the fetus. Trauma or excessive psychological pressure should also be avoided, and it is particularly important to maintain a relaxed attitude.

The treatment of fetal growth retardation needs to start with the cause, such as luteal support therapy with progesterone or HCG supplementation, uterine correction surgery, anticoagulation or immunotherapy, etc. During pregnancy, special attention should be paid to changes in embryonic development, regular prenatal check-ups, and early intervention should be performed if abnormalities are found.

It is important to effectively reduce the risk of fetal growth retardation through scientific pregnancy preparation. Pre-pregnancy and pregnancy checkups are important means to ensure the health of the embryo. If signs of miscarriage appear, you need to seek medical attention in time and develop a targeted treatment plan.
