What causes threatened miscarriage?

Threatened abortion is a condition that pregnant women need to be vigilant about. Its causes are diverse and complex, and can be mainly attributed to embryonic factors, maternal factors, paternal factors, and environmental factors.

1. Embryonic factors: Chromosomal abnormalities in the embryo or fetus often lead to early miscarriage. These abnormalities may be genetic or may be mutations that occur during the embryo's development. In addition to genetic factors, the development of the embryo, such as deformity and growth retardation, is also directly related to the stability of pregnancy.

2. Maternal factors: Pregnant women with systemic diseases, such as severe infection, high fever, severe anemia, etc., may affect the normal development of the fetus and cause threatened abortion. Endocrine abnormalities, such as luteal insufficiency and hyperprolactinemia, are also potential risks of miscarriage. Pregnant women with reproductive organ abnormalities, such as uterine malformation and intrauterine adhesions, may also hinder the implantation and development of the embryo.

3. Paternal factors: Studies have shown that sperm chromosome abnormalities can lead to spontaneous abortion. Prospective fathers should also pay attention to adjusting their lifestyle during pregnancy preparation and avoid contact with harmful substances to reduce the risk of sperm abnormalities.

4. Environmental factors: Excessive exposure to radiation and chemicals such as arsenic, lead, formaldehyde, benzene, etc. may lead to miscarriage. Pregnant women should try to avoid these unfavorable environments and ensure that the living and working environment is safe and pollution-free.

Understanding the causes of threatened abortion is important for preventing and treating this condition. Pregnant women should undergo regular prenatal checkups to promptly detect and treat potential risk factors. In life, pregnant women should also maintain good living habits and mentality, which is also the key to maintaining a stable pregnancy. If any abnormal symptoms occur, seek medical attention immediately to ensure the safety of mother and baby.
