What is the cause of recurrent spontaneous abortion?

Causes of recurrent spontaneous abortion: Recurrent spontaneous abortion refers to two or more spontaneous abortions in a row, which is a common clinical complication of pregnancy. Genetic factors, anatomical abnormalities, and immune factors are the main causes of this situation. Under normal circumstances, the pregnancy will not be rejected in the uterine cavity. If the immune balance between the mother and the fetus is broken, the mother will reject the fetus. Once the endocrine function is disordered, it may lead to miscarriage.

Spontaneous abortion is relatively common among women. Many women do not understand why they have spontaneous abortions. In fact, the probability of spontaneous abortion and artificial abortion is between 10% and 15% of pregnancy. Generally, in the case of spontaneous abortion, it is common in the early stage. There are many reasons for spontaneous abortion. So, what is the cause of recurrent spontaneous abortion?
Most spontaneous abortions are caused by abnormal chromosomes in the embryo. Of course, there are many other possible factors, such as autoimmune dysfunction, viral infection, and even severe malnutrition. Some pregnant women go on a diet to maintain their figure, which leads to malnutrition, which is also a cause of spontaneous abortion.
Spontaneous abortion mainly includes genetic defects. Regardless of the couple, chromosomal abnormalities of either party may lead to spontaneous abortion. Most embryos may experience early spontaneous abortion due to chromosomal abnormalities, including abnormal numbers and structures. In very rare cases, embryos with chromosomal abnormalities may also suffer from deformities or functional defects after full-term birth.
The causes of spontaneous abortion include maternal factors. If there are other diseases during pregnancy, such as systemic infection, high fever, etc., they will cause uterine contraction and lead to miscarriage. If there are reproductive organ abnormalities, endocrine abnormalities, bad habits, traumatic stimulation, immune function abnormalities, etc., these are also the main causes of spontaneous abortion.
After vaginal bleeding, women with early miscarriage will still have blood clots remaining in the uterine cavity. The remaining blood clots will stimulate the contraction of the uterus, and then continuous abdominal pain will occur. Women with late miscarriage often have paroxysmal uterine contractions before vaginal bleeding, so the abdominal pain of women with late miscarriage usually starts before vaginal bleeding.
In order to avoid spontaneous abortion, women should pay attention to a reasonable diet and a regular life in their daily lives. At the same time, they must take care of their health during pregnancy. The diet should be based on balanced nutrition. They should get more rest and avoid overwork. During pregnancy, if they are overworked or have bad living habits, they will cause spontaneous abortion.
