What causes threatened miscarriage?

Threatened miscarriage may be caused by a variety of factors, including genetics, environment, physiology, and pathology. Understanding these causes can help prevent and treat threatened miscarriage to improve the stability and well-being of pregnancy.

1. Genetic factors: Genetic abnormalities are one of the important causes of threatened abortion. Some chromosomal abnormalities, such as abnormal chromosome number or structural abnormalities, can lead to poor embryonic development and ultimately cause abortion. Such abnormalities usually cannot be avoided through routine prevention, but can be discovered in advance through prenatal genetic screening so that appropriate measures can be taken.

2. Environmental factors: Harmful substances in the environment such as heavy metals, radiation or chemical pollution may cause threatened abortion. Smoking, drinking and drug abuse can also increase the risk of abortion. In order to protect the health of pregnant women and fetuses, they should try to avoid contact with these harmful factors and keep them in a healthy living environment.

3. Physiological factors: Many health problems, such as thyroid dysfunction and diabetes, can easily affect the progress of pregnancy if they are not controlled. Maintaining a healthy balance of the body, taking prenatal checkups on time, and managing chronic diseases under the guidance of a clinician can effectively reduce the risk of miscarriage.

4. Trauma: An accidental impact on the abdomen may cause threatened abortion. During pregnancy, you must pay attention to safety, avoid dangerous sports, and wear protective equipment when necessary.

5. Pathological factors: As women age, their ovarian function declines, which may increase the possibility of miscarriage. Common pathological causes include uterine malformation or uterine fibroids, which can be properly treated through surgery or other clinical means to reduce the risk of miscarriage.

Threatened miscarriage is caused by a combination of genetic and non-genetic factors. Pregnant women at risk of miscarriage should actively undergo prenatal examinations to detect and treat potential problems as early as possible. A comprehensive physical examination and consultation before pregnancy is an important step to ensure a smooth pregnancy. A healthy lifestyle and scientific medical monitoring will play an important role in protecting the health of pregnant women and fetuses.
