What is the most likely cause of threatened miscarriage?

What is the most likely cause of threatened abortion? No matter what kind of disease occurs, it is necessary to understand the main cause of the disease for treatment. There are many causes of threatened abortion, and different causes have different treatment methods. So what is the most likely cause of threatened abortion?

1. Genetic defects: Fifty to sixty percent of early spontaneous abortions are caused by chromosomal abnormalities, which include abnormal numbers and structural abnormalities.

2. Reproductive organ diseases: Uterine hypoplasia, uterine malformation (bicornuate uterus, unicornuate uterus, septate uterus), uterine fibroids, etc. can affect embryo implantation and development and lead to miscarriage. Severe cervical lacerations and relaxation of the internal cervical os can lead to premature rupture of membranes and late miscarriage.

3. Immune dysfunction: Pregnancy is like an allogeneic transplant for the mother. There is a complex and special immunological relationship between the embryo, fetus and the mother. If the mother and the fetus are not immune compatible, the mother may reject the embryo and fetus and cause miscarriage.

4. Endocrine abnormalities: Hypothyroidism, poorly controlled severe diabetes, luteal insufficiency, etc. can all lead to miscarriage.

5. Trauma: Severe shock, uterine trauma (such as surgery, direct impact, excessive sexual activity) can also lead to miscarriage. Excessive tension, anxiety, fear, sadness and other mental factors can also cause miscarriage.

6. Systemic diseases: Systemic infection and high fever during pregnancy can cause uterine contraction and lead to miscarriage. Bacteria and viruses enter the fetal blood circulation through the placenta, which can cause fetal death and miscarriage. Severe anemia or heart failure in pregnant women can cause fetal hypoxia and miscarriage. Chronic nephritis or hypertension in pregnant women can also cause miscarriage if the placenta is infarcted.

7. Bad habits: Excessive smoking, alcoholism, excessive coffee drinking, drug use, etc. by pregnant women can all cause miscarriage.

8. Environmental factors: Harmful chemicals, radiation, high-decibel noise, high temperature, microwave radiation, etc. can all cause damage to the embryo or fetus and cause miscarriage.

Among the causes of threatened abortion mentioned above, it can be seen that environmental factors are also one of the reasons for this phenomenon in Caocheng. In the lives around us, the environmental conditions are getting worse and worse, and are getting worse and worse, which poses a great threat to people's health, especially for pregnant women. Therefore, the only reason we can do is to protect the environment and give ourselves a healthy home.
