How to determine if the fetus has stopped developing

The fertilized egg is actually very similar to a seed. It has to go through complex hardships before it can eventually grow into a healthy and lovely baby. If the embryo develops to a certain stage but stops developing due to some factors, how can we determine that the fetus has stopped developing? There are mainly two points: ① The reason of the embryo itself ② The illness of the pregnant woman. These are ways to determine that the fetus has stopped developing. You can also go to the hospital for relevant examinations.

1. Common reasons why the fetus of each pregnant woman stops developing

① Factors related to the embryo itself, such as chromosomal abnormalities, or the failure of certain important tissues and organs to develop normally in the early stages of embryonic development. This situation is a form of natural selection, that is, "survival of the fittest and elimination of the inferior."

② Placental maldevelopment The fetus grows and develops in the mother's body, and the mother's nutrients and oxygen are mainly transported to the fetus through the placenta. If the placenta is maldeveloped or diseased, the fetus will not get nutrients and oxygen and will stop growing.

③ Maternal illness: The pregnant woman suffers from the following systemic diseases, such as severe diabetes, hypertension, heart disease, viral hepatitis, severe anemia, chronic nephritis, or malnutrition, especially vitamin deficiency, as well as mercury, lead, alcohol poisoning, etc.; the pregnant woman is infected with viruses, such as rubella virus, cytomegalovirus, herpes simplex virus, toxoplasmosis, or suffers from acute infectious diseases such as influenza, typhoid fever, pneumonia, etc.; reproductive organ diseases, such as uterine malformation, uterine fibroids, or intrauterine adhesions.

④ Abnormality of the maternal immune system There is a complex and special immunological relationship between the embryo and fetus and the mother, which prevents the embryo and fetus from being rejected. If there is immune incompatibility between the mother and the fetus, the mother may reject the fetus and prevent the development of the embryo, which is called "immune rejection."

⑤ Reproductive endocrine factors: During the early development of the embryo, three important hormone levels are needed to maintain, namely estrogen, progesterone, and human chorionic gonadotropin. If the mother's own endogenous hormones are insufficient, the embryo will stop developing.

⑥ Adverse external factors such as trauma, overwork, mental stimulation; taking drugs that affect fetal development; contact with toxic chemicals, inferior decoration materials, etc.; exposure to radiation or large amounts of electromagnetic radiation.

The main symptoms of fetal development cessation include abdominal pain, vaginal bleeding, and the sudden disappearance of early pregnancy reactions such as morning sickness and breast tenderness. When the fetus stops developing, pregnant women should go to the hospital in time to actively find out the cause and ensure that the fetus develops normally.
