Let’s find out what are the causes of spontaneous abortion?

There are five reasons for spontaneous abortion. The first is embryonic incompleteness and abnormal fertilized eggs, which are the main causes of spontaneous abortion. The second is endocrine dysfunction, which affects the development of fertilized eggs, resulting in abortion. The third is reproductive organ disease, such as uterine malformation or uterine hypoplasia. The fourth is systemic disease of pregnant women, such as anemia, mental failure, or pneumonia and typhoid fever in pregnant women. The fifth is trauma. Impact or squeezing of the abdomen can cause abortion.

Although spontaneous abortion is not directly caused by human factors, there are many reasons for spontaneous abortion, and indirect abortion caused by human factors cannot be ruled out, so expectant mothers must always pay attention to their physical condition. So let's take a look at the reasons for spontaneous abortion.
1. Incomplete embryonic development <br/>Abnormal fertilized eggs are the main cause of early miscarriage. About 80% of miscarriages in the first two months of pregnancy are due to some defects in sperm and eggs, which cause the embryo to develop to a certain extent and then terminate. Therefore, the original embryonic tissue cannot be found in the discharge of this type of miscarriage.
2. Endocrine dysfunction <br/>The fertilized egg can only implant on the uterine wall and grow into a fetus under the action of progesterone. When the body secretes insufficient progesterone, the uterine decidua will be underdeveloped, thus affecting the development of the fertilized egg and easily causing miscarriage. If prostaglandins increase, it will cause frequent contractions of the uterine muscles, which can also lead to miscarriage. Reduced thyroid function can cause cell oxidation capacity disorders, which in turn affects the growth and development of the embryo and causes miscarriage.
3. Reproductive organ diseases <br/>Uterine malformations such as bicornuate uterus, septate uterus, and uterine hypoplasia. Pelvic tumors, especially submucosal myomas, can affect the growth and development of the fetus and lead to miscarriage. Cervical relaxation or deep cervical tearing, late miscarriage, and premature rupture of membranes.
4. Systemic diseases of pregnant women <br/>Pregnant women with acute infectious diseases such as influenza, typhoid fever, pneumonia, etc., 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 with chronic diseases such as severe anemia, heart failure, chronic nephritis and hypertension may cause fetal disability and miscarriage due to placental infarction and intrauterine hypoxia. Malnutrition of pregnant women, especially vitamin deficiency, as well as mercury, lead and alcohol poisoning can all cause miscarriage.
5. Trauma : The abdomen of a pregnant woman is hit or squeezed by external force, or she falls or participates in heavy physical labor or strenuous sports; abdominal surgery such as appendicitis or ovarian cyst surgery can all cause uterine contraction and miscarriage.
