What causes the fetus to stop developing during pregnancy
Pregnancy is something every woman looks forward to, but stopping the development of the fetus is a very worrying thing. Fetal arrest refers to the natural cessation of growth of the embryo or fetus, which causes great distress to pregnant women and their families. So, what is the cause of fetal arrest? How should we prevent it?
Cause 1: Chromosomal abnormalities
The most common cause of fetal arrest is chromosomal abnormalities, which are caused by certain errors during the development of the embryo, resulting in a large number of missing or extra cells. When there is a problem with embryonic development, the fetus does not grow naturally and therefore stops growing. In addition, about 50% of early miscarriages are also caused by chromosomal abnormalities in sperm cells, because such abnormalities can cause the early fetal growth to stop.
The best way to prevent this is to undergo genetic testing before pregnancy to ensure that there are no genetic abnormalities on either side. Be careful to avoid smoking, drinking and other behaviors that are harmful to the embryo.
Reason 2: Insufficient luteal body function
Luteal insufficiency is also a cause of fetal arrest. After ovulation, the ovary will form a corpus luteum based on the oocyte. The corpus luteum secretes estrogen and progesterone to provide nutrition and support for the development of the embryo and maintenance of pregnancy. If the corpus luteum is insufficient, it will affect the response of target cells to progesterone, causing the fetus to stop developing.
The best way to prevent luteal insufficiency is to seek medical advice early in pregnancy. Your doctor may give you progesterone or other hormone supplements to ensure that the corpus luteum is functioning properly to help the fetus develop.
Cause three: infection
If a pregnant woman is infected with certain diseases during pregnancy, the fetus may stop growing. This is because the infection can cause too much or too little amniotic fluid, which affects cell growth and causes the fetus to stop developing. The most common infectious viruses include cytomegalovirus, rubella virus, cytomegalovirus, etc.
Pregnancy safety check-ups can help pregnant women detect infections early and treat them promptly. When you have uncomfortable symptoms after pregnancy, please consult your doctor in time.
Reason 4: Use of macrocycloalkanes
Some macrocycloalkanes, such as the tumor treatment drugs cyclophosphamide and methotrexate, may cause the fetus to stop developing. Therefore, pregnant women should follow doctor\’s advice, carefully consider the risks and benefits of using drugs, and try to avoid using toxic or harmful drugs.
Summary
There are many reasons why a fetus may stop developing during pregnancy, including chromosomal abnormalities, luteal insufficiency, infection, and the use of macrocyclic drugs. In order to prevent this phenomenon, pregnant women need to follow the doctor\’s advice, pay attention to diet, rest and exercise during pregnancy, maintain a good physical condition, and avoid using harmful or toxic drugs to ensure the normal development of the fetus.
