What are the causes of unexpected miscarriage?

Pregnancy is a period of both danger and happiness for women, because pregnancy is not so safe. Many women suffer from symptoms of accidental termination of pregnancy due to various reasons. These are typical symptoms of miscarriage, which have a great impact on people's bodies and hit women's mental health. What are the causes of accidental miscarriage? Let's take a look at the explanation below.

1. Incomplete embryonic development: 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 causes the embryo to develop to a certain extent and then terminate. Therefore, the original embryonic tissue cannot be seen in the discharge of this type of miscarriage.

4. Systemic diseases of pregnant women: 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 contractions and cause miscarriage. Pregnant women suffering from chronic diseases such as severe anemia, heart failure, chronic nephritis and hypertension may suffer 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 cause miscarriage.
