What are the factors that lead to threatened abortion? In fact, there are many factors that cause threatened abortion in our daily life. It is well known that pregnant women's bodies are relatively weak, and signs of miscarriage may occur if they are not careful, so they need extra care. So, what are the factors that lead to threatened abortion?

1. Embryonic factors: Abnormal embryonic development or blood type incompatibility is the most common cause of early miscarriage.

2. Maternal factors: The mother suffers from acute or chronic diseases, such as anemia, hypertension, chronic nephritis, heart disease or viral infection, or high fever, which causes uterine contraction and leads to threatened abortion. Reproductive organ diseases such as uterine malformation, pelvic tumor, loose or lacerated uterine cavity can also lead to threatened abortion.

3. Immune factors: After the mother becomes pregnant, the mother rejects the fetus due to immune incompatibility between the mother and the fetus.

4. Endocrine dysfunction: mainly corpus luteum dysfunction and hypothyroidism in expectant mothers.

5. External factors: If the expectant mother is exposed to harmful substances such as mercury, lead, cadmium, or a toxic environment; or is disturbed and influenced by external physical factors such as high temperature and noise, it may also lead to threatened abortion.

Pregnant women should pay attention to choosing foods that are rich in various vitamins and trace elements and easy to digest, such as various vegetables, fruits, beans, eggs, meat, etc. People with weak stomach and cold intestines should be cautious about taking foods with cold properties, such as mung beans, white fungus, lotus seeds, etc.; people with yin deficiency and excessive fire should be cautious about taking foods that are easy to cause internal heat, such as rooster, beef, dog meat, carp, etc.
