What are the causes of premature abortion?

For pregnant women, the most feared thing is threatened abortion, because we all know that this will directly affect the fetus. In modern life, many women will be affected by this problem. So here I will introduce to you what are the reasons that may easily lead to threatened abortion, so that you can pay attention to prevention in your life.

Embryo (30%):

The main reason is the imperfection of the father's or the mother's germ cells. Although the imperfect germ cells can barely combine to form an embryo, they will eventually die early and will not be able to "ripen off the vine" and be born at full term. Miscarriage caused by this reason can actually be said to be a good thing. Because an abnormal fetus, if it is really born 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 among pregnant women is also one of the causes of miscarriage. Some pregnant women experience severe nausea and vomiting in the early stages of pregnancy, which leads to extreme nutritional deficiency, which has a great impact on the development of the embryo and is also prone to miscarriage.

Maternal aspects (30%):

After a woman becomes pregnant, if she is exposed to emotional instability, anger, sadness and other mental stimulation, 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. Suffering from 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 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, may cause miscarriage.

Other aspects (30%):

Sexual life throughout pregnancy should be treated with caution. Inappropriate sexual life, especially in the early stages of pregnancy, can easily cause miscarriage. During 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, so as not to cause miscarriage. During the perinatal period, if the gynecological examination is performed with rough techniques, it can also be one of the causes that easily cause miscarriage. This is especially important for pregnant women with weak constitutions. Poisoning by drugs and certain chemicals, such as quinine, carbon monoxide, aluminum, phosphorus, mercury, and benzene, can often make the embryo difficult to preserve.

Through these introductions, we will find that there is a relationship between factors that may cause threatened abortion and the factors on the fetus and the mother. Before getting pregnant, women should prepare for pregnancy and have regular prenatal checkups during pregnancy so that they can understand the development of the fetus at each stage.
