What are the causes of miscarriage? Let's take a look at it.

There are many reasons for miscarriage during pregnancy. Most early miscarriages are caused by chromosomal abnormalities or congenital diseases in the embryo itself, which is a process of natural elimination. In addition, abnormalities in the reproductive tract can also lead to abnormal embryo implantation and development, leading to miscarriage. Systemic diseases of the mother, acute infectious diseases such as influenza, typhoid fever, pneumonia, or malnutrition in pregnant women can all lead to miscarriage. Endocrine abnormalities in pregnant women, immune factors, paternal factors, and environmental factors can also cause miscarriage.

Many pregnant women will be very careful to protect the fetus in their abdomen. In daily life, there are no bumps and bumps. However, accidents still happen, and the fetus will still be miscarried for no reason, which makes pregnant women feel very uncomfortable. So, what are the causes of miscarriage? Let's take a look at it together.
1. Embryonic factors <br/>Mainly chromosomal abnormalities of the embryo and fetus, it is the most common cause of early miscarriage, accounting for 50%-60%, and mid-term miscarriage can also account for 1/3.
2. Abnormalities of the reproductive tract <br/>Mainly uterine malformations, uterine fibroids, adenomyosis, and intrauterine adhesions can also lead to abnormal embryo implantation and development and cause miscarriage.
3. Systemic diseases of pregnant women <br/>Pregnant women suffer from 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.
4. Endocrine factors <br/>For example, endocrine abnormalities, mainly hypothyroidism, diabetes, luteal insufficiency, hyperprolactinemia, polycystic ovary syndrome are also causes of miscarriage.
5. Immune factors and paternal factors <br/>Spontaneous abortion is mainly caused by chromosomal abnormalities in sperm.
6. Environmental factors <br/>Mainly due to exposure to radiation or toxic substances, which can also cause miscarriage.
7. Bad living habits can lead to miscarriage .<br/>Habits such as staying up late, overwork, inappropriate sexual life, smoking, alcoholism, drug abuse, etc. can cause miscarriage.
8. Lead to accidents such as falling, collision, being frightened, etc.
