Fetotoxicity means that the fetus is infected with some pathogens or toxins in the mother\’s body, causing fetal development abnormalities or diseases. Fetotoxicity is a serious fetal disease that, if not diagnosed and treated in time, will have a serious impact on the health and growth of the fetus. Symptoms of fetal poisoning mainly manifest in the following aspects: Fetal growth arrest: The fetus grows slowly in the mother\’s body, weight is lower than normal, muscle atrophy, larger head, short limbs, poor bone development, and mental retardation may occur after birth. and body dysmorphia issues. Fetal nervous system abnormalities: The fetus is affected by infection or toxins in the mother\’s body, which may lead to abnormal nervous system development and neurological diseases, such as hydrocephalus, encephalitis, etc. Abnormal fetal organ development: The fetus is affected by infection or toxins in the mother\’s body, which may lead to abnormal organ development, heart malformation, lung dysplasia and other problems. Decreased fetal immune function: The fetus is affected by infection or toxins in the mother\’s body, which may lead to decreased immune function, susceptibility to infection, and may even lead to death. The main causes of fetal poisoning include the following aspects: Maternal infection: The mother is infected with certain pathogens during pregnancy, such as viruses, bacteria, molds, etc. These pathogens can be passed to the fetus through the placenta, causing fetal infection. Maternal exposure to toxins: The mother is exposed to certain toxic substances during pregnancy. For example, women are exposed to certain toxic drugs and chemicals. These toxins can be passed to the fetus through the placenta, causing fetal poisoning. Other factors: Abnormal maternal immune system, etc., may also lead to fetal infection. The treatment of fetal poisoning is mainly based on the cause of the disease, such as antibiotic treatment, removal of toxins, improvement of maternal immune function, etc. At the same time, if the fetus develops abnormally or has malformations, professional medical intervention and surgical treatment are required. To sum up, fetal poisoning is a serious fetal disease. If not treated in time, it will have a serious impact on the health and growth of the fetus. Pregnant women need to pay attention to maintaining healthy living habits during pregnancy and avoid infections and exposure to toxic substances to protect the health of the fetus. At the same time, if any abnormality is found in the fetus, seek medical treatment promptly and receive professional treatment and intervention to ensure the health and growth of the fetus.
