What are the causes of fetal arrest in late pregnancy?

If the fetus stops growing in late pregnancy, it will be a bolt from the blue for the pregnant mother. So why does the fetus stop growing in late pregnancy? What are the reasons for fetal arrest in late pregnancy? Next, this article will introduce the eight major reasons for fetal arrest in late pregnancy for your reference only. If you want to know the reasons for fetal arrest in late pregnancy, please continue reading! Please see the detailed introduction below.

What are the causes of fetal arrest in late pregnancy? The reasons for late pregnancy arrest are as follows:

1. Uterine environment: The uterus is the only home for the embryo. A good uterine environment will directly affect the development of the embryo. Uterine fibroids, endometriosis, endometrium that is too thin or too thick, intrauterine adhesions, and congenital cervical relaxation may all be factors that lead to embryonic development termination.

2. Endocrine disorders: Insufficient endogenous hormones in women, such as insufficient luteal function and insufficient progesterone secretion, may cause embryo arrest and miscarriage.

3. Environmental factors: Pregnant mothers are exposed to a lot of physical factors such as X-rays, microwaves, noise, ultrasound, high temperature, etc. before or after pregnancy. Heavy metals such as aluminum, lead, mercury, and zinc are also factors that affect the implantation of fertilized eggs.

4. Chromosomal abnormality: Chromosomal abnormality is an important factor that causes the embryo to stop developing, but this only happens in a very small number of people. If this is indeed the reason, you will not be able to get pregnant. There is currently no good solution to chromosomal defects.

5. Bad living habits: Survey data from many countries show that smoking and drinking are very harmful to the development of the fetus. Women's smoking and drinking will directly affect the female endocrine and reproductive system functions. Pregnant mothers' smoking and drinking will cause fetal malformations.

6. Infection: Usually during the pre-pregnancy check-up or early pregnancy check-up, doctors will recommend expectant mothers to undergo the five eugenics tests, also known as the five teratogenic tests (abbreviated as TORCH). By testing viral antibodies, it is possible to determine whether the expectant mother's body is in the acute infection stage of a certain virus. If the expectant mother is in the acute infection period of viruses such as rubella, cytomegalovirus or toxoplasmosis, it may indeed cause fetal malformation or death. It is recommended that expectant mothers survive the acute infection period and wait until the IgM antibody turns negative before conceiving.

7. Advanced age: As the age of the expectant mother increases, the chance of fetal growth retardation will gradually increase. The latest data shows that for expectant mothers between the ages of 20 and 30, the chance of fetal growth retardation is only 9% to 17%; if it is 35 years old, the proportion rises to 20%; if it is 40 years old, the proportion rises to 40%; and by the age of 45, the proportion is as high as 80%.

8. History of spontaneous abortion: The risk of fetal growth retardation will also increase. Therefore, once a miscarriage occurs, it is important to find out the cause and actively treat it to avoid affecting the second pregnancy.

The above is an introduction to the causes of fetal arrest in late pregnancy. I believe that after reading the above introduction, you will have a certain understanding of the causes of fetal arrest in late pregnancy. Therefore, for those who are preparing to get pregnant or are pregnant, you must try to avoid the above reasons! Only in this way can you give birth to a healthy baby.
