How can you have a spontaneous abortion?

1. Embryonic hypoplasia: Abnormal pregnant eggs are the main cause of early abortion. About 80% of abortions in the first two months of pregnancy are due to some defects in sperm and eggs, which leads to the termination of embryo development to a certain extent. Therefore, there is no original embryonic tissue in the discharge of this abortion.

Second, endocrine dysfunction: under the action of progesterone, fertilized eggs can be implanted on the uterine wall and grow into fetuses. When progesterone secretion in the body is insufficient, the decidua of uterus will be stunted, which will affect the development of fertilized eggs and easily lead to abortion. If prostaglandin increases, it will cause frequent contraction of uterine muscles and also lead to miscarriage. The decline of thyroid function can hinder the oxidation ability of cells, and then affect the growth and development of embryos and abortion.

Third, reproductive organs diseases: uterine malformations such as double horn uterus, mediastinal uterus, uterine dysplasia and so on. Pelvic tumors, especially submucosal fibroids, will affect the growth and development of the fetus and lead to abortion. Relaxation of uterine orifice or deep tearing of cervix can cause premature rupture of membranes and late abortion.

Fourth, systemic diseases of pregnant women: pregnant women suffer from acute infectious diseases such as influenza, typhoid fever and pneumonia, and bacterial toxins or viruses enter the fetus through the placenta, causing fetal poisoning and death. High fever can promote uterine contraction and cause miscarriage. Pregnant women suffer from severe anemia, heart failure, chronic nephritis, hypertension and other chronic diseases, which can lead to fetal disability and abortion due to placental infarction and intrauterine hypoxia. Malnutrition of pregnant women, especially vitamin deficiency, and mercury, lead and alcoholism may all lead to abortion.

Five, trauma: pregnant women's abdomen is hit and squeezed by external forces, pregnant women fall or participate in heavy physical labor, strenuous exercise; Abdominal surgery, such as appendicitis or ovarian cyst surgery, can lead to uterine contraction and abortion.

Sudden change of mood of intransitive verbs: pregnant women's mood is greatly stimulated, and excessive sadness, panic, fear and emotional excitement can cause internal environment imbalance of pregnant women, induce uterine contraction and cause abortion.

Seven, placental dysplasia: the growth and development of the fetus in the mother, mainly through the placenta to transport maternal nutrients and oxygen to the fetus, if the placenta dysplasia or disease, the fetus can not get nutrients and oxygen and stop growing and cause abortion.

Eight, maternal and fetal blood type incompatibility: pregnant women have received blood transfusion in the past, or produced coagulation factors that are incompatible with blood type during pregnancy, which will cause agglutination and hemolysis of fine cells in the fetus, thus causing abortion.

The above analysis of the eight causes of spontaneous abortion of pregnant women provides you with reference. I hope everyone can pay attention to their physical changes and avoid unnecessary consequences caused by abortion.

Signs, abdominal pain after pregnancy, vaginal bleeding. Habitual abortion, also known as repeated spontaneous abortion, refers to the termination of pregnancy many times before Monday.
