A lot of vaginal discharge after miscarriage

After a miscarriage, women will feel that their leucorrhea becomes abnormally large, which they will find very strange and fear that their bodies will have some sequelae. In fact, in the early stages of miscarriage, women may indeed experience endocrine disorders, which will cause their leucorrhea to be abnormal. However, after a period of time, it will slowly return to normal. This is a very common phenomenon.

1. Chromosomal abnormalities Chromosomal abnormalities include abnormal chromosome number, such as monosomy, trisomy, and polyploidy; structural abnormalities, such as breakage, deletion, and translocation can all lead to miscarriage. Some people have conducted chromosomal research on spontaneous abortion and therapeutic abortion and found that karyotype abnormalities account for 60% of spontaneous abortions. Karyotype abnormalities are often accompanied by structural abnormalities such as in the fetus or placenta. However, the fetuses aborted by those with normal karyotype are mostly normal.

2. Endocrine disorders: Excessive estrogen and insufficient progesterone are also causes of early miscarriage. Because the placenta is formed and replaces the function of the corpus luteum of pregnancy during the 12th to 14th week of pregnancy, endocrine disorders are prone to occur, especially corpus luteum insufficiency. In addition, the lack of thyroid hormone hinders the cellular oxidation process, and hyperthyroidism and diabetes are prone to miscarriage.

3. Placental abnormalities and placental endocrine insufficiency. Deciduaitis during early pregnancy can cause bleeding or hyperplasia of the basal decidua, dissolution of the chorionic epithelial cells and decidual cells, and blockage of blood vessels in the villi, affecting the absorption and transportation of nutrients, resulting in the separation of the fertilized egg from the attachment site, bleeding and miscarriage. In addition, huge infarction in the placenta can reduce the function of the placenta and affect the survival of the fetus; and placenta previa and placental villus edema and degeneration leading to miscarriage are not uncommon. After pregnancy, the levels of β-hCG, hPL, P, E2, and estrone in the mother's blood decrease during early pregnancy, resulting in 50% miscarriage.

4. Blood type incompatibility: Due to previous pregnancy or blood transfusion, the Rh factor and incompatible ABO blood type factor produce antibodies in the mother. During this pregnancy, the antibodies enter the fetus through the placenta and agglutinate with red blood cells to produce hemolysis, resulting in miscarriage.

5. Psychoneural factors such as fright, severe mental stimulation, etc. can also cause miscarriage. In recent years, research has shown that noise and vibration have a certain impact on human reproduction.

6. Maternal systemic diseases

1. Severe acute infectious diseases and contagious diseases: such as lobar pneumonia, which is often accompanied by high fever leading to uterine contractions and/or embryonic death[1], can cause miscarriage.

2. Chronic diseases: severe anemia, heart disease, and heart failure can cause fetal hypoxia, suffocation and death; chronic nephritis and severe hypertension can cause placental infarction or premature detachment and cause miscarriage.

3. Malnutrition or drug poisoning: Vitamin deficiency, especially vitamin E-tocopherol deficiency, chronic poisoning such as mercury, lead, alcohol and morphine can all cause miscarriage.

7. Reproductive organ diseases Uterine malformations, such as bicornuate uterus and uterine septate, are often the cause of miscarriage.

8. Immune factors: For those with unknown causes, studies in recent years have found that most are closely related to immune factors. [2]
