What causes fetal arrest?

Fetal arrest is a condition in which an embryo stops developing during pregnancy and eventually dies. Fetal arrest usually occurs early in pregnancy rather than after the fetus has reached a certain stage of development, so it can be very frustrating and confusing. While the causes of fetal arrest can vary, here are some common ones. 1. Chromosomal abnormalities: Chromosomal abnormalities are one of the most common causes of fetal arrest. These abnormalities usually occur during fertilization, causing the embryo to stop developing during the early stages of development. Common chromosomal abnormalities include trisomy, tetrasomy, etc. 2. Endometrial problems: The endometrium is the environment required for embryo implantation and development. If there is a problem with the lining of the uterus, such as being too thin or too thick, the embryo may not be able to implant in it or get enough nutrients, causing fetal arrest. 3. Hormone issues: Hormones play an important role in maintaining pregnancy. If hormone levels are imbalanced, such as progesterone levels that are too low, this can lead to fetal arrest. 4. Maternal immune system problems: While the maternal immune system protects the body from external invasion, it may also have adverse effects on the embryo. If the mother\’s immune system is abnormally active, it may attack the embryo, causing fetal arrest. 5. Maternal health issues: The health of the mother is crucial to the development of the fetus. If the mother has a medical condition or suffers from a chronic disease, such as diabetes, thyroid problems, etc., the risk of fetal arrest may be increased. 6. External environmental factors: External environmental factors may also affect fetal development. For example, exposure to harmful substances such as toxins and radiation may cause fetal arrest. The above are just some common reasons, the actual situation may be more complicated. It is very important for couples who have experienced fetal stoppage to understand the cause of the fetal stoppage, which can help them better deal with this dilemma and take appropriate measures to reduce the risk of fetal stoppage in future pregnancies. If you or your partner have experienced fetal arrest, it is recommended to consult a professional medical institution or obstetrician-gynecologist, who can provide more detailed consultation and advice based on your specific situation. Psychological counseling is also very important during this process, because fetal arrest may have a great impact on the couple\’s mental health.
