Briefly describe the basic causes of threatened abortion

Threatened abortion threatens the health of pregnant women and even the life of the fetus in the womb. Therefore, we must pay attention to it and understand the causes of threatened abortion. We must prevent and treat it early. So what are the basic causes of threatened abortion? Let's find out.

Threatened abortion refers to a small amount of vaginal bleeding that occurs in early pregnancy and stops and comes and goes, accompanied by mild lower abdominal pain and backache. It may lead to miscarriage, or it may continue pregnancy after proper treatment. It is mainly caused by the weak constitution of pregnant women, or fatigue, trauma (including improper vaginal examination and sexual intercourse). It is equivalent to "fetal bleeding" in traditional Chinese medicine.

Embryo. The main reason is the imperfect reproductive cells of the father or mother. Although the imperfect reproductive cells can barely combine to form an embryo, they will eventually die early and cannot "ripen off the vine". Abortion caused by full-term delivery can actually be said to be a good thing. Because an abnormal fetus, if it is really born at full term, will also have deformities or abnormalities. Other reasons such as insufficient oxygen supply to the umbilical cord, amniotic fluid disease, placental virus infection, and certain gynecological inflammations can also cause miscarriage. Malnutrition of pregnant women is also one of the causes of miscarriage. Some pregnant women have severe nausea and vomiting of pregnancy in the early stage, resulting in extreme nutritional deficiency, which has a great impact on the development of the embryo and is prone to miscarriage.

Maternal aspect. After a woman becomes pregnant, if she is emotionally unstable, angry, sad, or other mental stimulation, it will disrupt the activity of the cerebral cortex, causing the uterus to contract and force the embryo out, or causing the embryo to die in the uterus. Acute infectious diseases such as influenza and rubella can cause miscarriage due to high fever and toxins released by bacteria and viruses. Endocrine disorders, such as corpus luteum, pituitary gland, and thyroid dysfunction, as well as excessive uterine retroflexion in uterine hypoplasia, which causes the uterine cavity to hinder the development of the embryo, can all cause miscarriage.

Other aspects. Sexual life should be cautious during the entire pregnancy period. Inappropriate sexual life, especially in the early stages of pregnancy, can easily cause miscarriage. In the second trimester of pregnancy, sexual life should also be moderate, avoiding sexual intercourse positions that compress the pregnant woman's abdomen and rough sexual intercourse to avoid causing miscarriage. During the perinatal period, if the gynecological examination is done roughly, it is also one of the causes that can easily cause miscarriage. This is especially important for pregnant women with weak constitutions.
