What is threatened miscarriage?

What is threatened abortion? Threatened abortion is a common phenomenon among pregnant women. Threatened abortion is characterized by only a small amount of vaginal bleeding, accompanied by lower abdominal pain and back pain. If a vaginal examination is performed, it can be seen that the size of the uterus is consistent with the month of pregnancy. So, what is threatened abortion? Let's take a look.

1. Threatened abortion is mainly caused by genetic factors causing embryo abnormalities. Abortion caused by this can actually be considered a good thing, because an abnormal fetus, if it is really born at full term, will also have deformities or abnormalities.

2. Insufficient umbilical cord oxygen supply, amniotic fluid disease, placental virus infection and certain gynecological inflammations can also cause threatened abortion.

3. Malnutrition of pregnant women is also one of the causes of miscarriage. Some pregnant women have severe nausea and vomiting in the early stages of pregnancy, resulting in extreme nutritional deficiency, which has a great impact on the development of the embryo and is prone to miscarriage.

4. After a woman becomes pregnant, if she is exposed to emotional instability, anger, sadness and other mental stimulations, it will disrupt the functional activities of the cerebral cortex, causing the uterus to contract and force the embryo out, or cause the embryo to die in the uterus.

5. Endocrine disorders, such as dysfunction of the corpus luteum, pituitary gland, and thyroid gland, as well as excessive retroflexion of the uterus in uterine hypoplasia, which causes the uterine cavity to hinder the development of the embryo and may also cause miscarriage.

If a pregnant woman has an acute infectious disease such as influenza or rubella, she may suffer from miscarriage due to high fever and toxins released by bacteria and viruses. If you are not careful during sex during pregnancy, especially in the early stages of pregnancy, if the sexual intercourse position presses on the pregnant woman's abdomen or is rough, it may also cause threatened miscarriage.
