Five factors leading to fetal malformation

Every pregnant mother wants to give birth to a healthy and intelligent baby, but there are many risk factors, and one carelessness may hurt the baby. Therefore, during pregnancy, we should pay special attention to the following risk factors: 1, radiation and radiation, drugs, hereditary diseases, virus infection, nutrition, women are prone to have deformed children, and some prospective parents are anxious to ask about radiation and radiation. The harm of X-rays to human body is recognized. Needless to say, even fetuses and adults will be killed by cells. X-ray can not only cause fetal malformation, abortion and stillbirth, but also increase the incidence of hematological tumors in children after 10 years. Even in the first three months of pregnancy, X-ray irradiation can still have an impact on the fetus. Therefore, we should pay attention to avoid X-ray irradiation after marriage. Computers and televisions are indispensable advanced tools in people's daily life. How much influence will computer or TV screen radiation have on the fetus? As far as the information available at present is concerned, the medical authorities have not made a definite conclusion, and there is still a lack of large-scale population-based comparative research. Theoretically, the radiation of display screen is safe for human body. But is it safe for * * *, eggs, fertilized eggs, embryos and fetuses? For the sake of eugenics, it is recommended to make preparations in advance 3 months before pregnancy to reduce the net working time in front of the display screen. Preferably within 2-4 hours every day. Try to keep a distance of 70cm from the display screen. 2. Drugs It has been reported abroad that 70-80% of pregnant women have taken drugs during pregnancy, 2-3% of newborn birth defects may be caused by drugs, and more than half of unexplained birth defects may be related to the interaction between drugs and diseases. Most drugs harmful to the fetus are taken without knowing the pregnancy, especially the pregnancy reaction in the first trimester is regarded as a disease, and many drugs are taken unintentionally. When they know about pregnancy, they are very worried, and they often can't get a satisfactory answer when seeking the help of doctors. Because nothing is 100%, and there are few absolutely positive answers. The solution is to think about whether you are pregnant after marriage, always put this in the first place, and use drugs carefully. In addition, some prospective parents overdose and don't take medicine under any circumstances. Once a pregnant woman was diagnosed with severe pyelonephritis. She stayed at home for a week, with a temperature of 39 degrees Celsius and an abscess around her kidney. We should consider the influence of drugs on the fetus, but we should also consider the influence of the disease itself on the fetus. We should look at this problem objectively and weigh its advantages and disadvantages. Don't take medicine by yourself when you are sick, but see a doctor in time. The influence of drugs on the fetus is related to the gestational age, and the embryonic period (2 ~ 8 weeks of pregnancy) is the most sensitive to drugs, that is to say, in the early pregnancy, you should be more careful when using drugs, and it is best not to use any drugs. Except for the following three cases: (1) pregnant women have definite symptoms; (2) The influence of pregnant women's diseases on the fetus is greater than that of drugs; (3) The disease has seriously affected the health of pregnant women. At this time, it is extremely important to choose the types of drugs. Choosing drugs with both side effects and small side effects requires careful planning by doctors, rather than writing prescriptions with pens. Reading: Use of commonly used drugs during pregnancy 3. Hereditary diseases such as hemophilia, the woman who carries the gene should interfere with the sex of the fetus, because hemophilia is the mother who carries the disease-causing gene, and the boy may get sick. If the father is a hemophiliac, the daughter may be a carrier of the disease-causing gene. Therefore, when the father is a hemophiliac, he should have a boy. If the mother is a gene carrier that causes hemophilia, she should have a girl. There are some chromosomal abnormalities and genetic diseases that will not be listed one by one. 4. Virus infection Because hepatitis virus has hepatitis B immunoglobulin and hepatitis B vaccine, and there is no report of fetal malformation caused by hepatitis B virus, hepatitis B virus infection no longer scares prospective parents, but should focus on STORCH. What teratogenic viruses are there? S is the abbreviation of syphilis; T is short for toxoplasmosis; O is the abbreviation of OTHER; R is the abbreviation of rubella; C is the abbreviation of cytomegalovirus; H is the abbreviation of HERPESSIMPLEX; If pregnant women are infected with these viruses, it will lead to fetal abortion, stillbirth, deformity and premature delivery. The probability of women of childbearing age being infected with these viruses is not low. When conducting pregnancy tests, doctors may test pregnant women for viral infection. When there is a positive result, both husband and wife are extremely afraid. Because there is no better treatment to prevent the virus from infecting the fetus, prevention is extremely important. We can't ignore the harm of influenza virus to fetus. Pregnant women suffering from influenza may have the following effects on embryos or fetuses: 1, abortion, premature delivery and high incidence of stillbirth. After the separation and culture of aborted fetal tissues, it is found that there are a large number of viruses in many important organs of stillbirth, and it is these viruses that destroy the normal development of fetal tissues and bring fatal harm. The younger the infected fetus, the greater the harm. In addition, influenza can cause high fever, toxemia, hypoxia, dehydration and acidosis, which can cause great damage to the mother, and may also affect the placenta, the blood circulation and oxygen supply of the fetus, and ultimately affect the development of the fetus. 2. Animal experiments leading to fetal malformation show that anencephaly can occur if the mother has a high fever during the closing period of fetal anterior neural tube. There are similar reports in the human body, so the incidence of severe viral cold, high fever and fetal malformation in the first three months of pregnancy is high. In order to prevent birth defects, special attention should be paid to influenza, which can cause high fever and other complications. Especially in the early pregnancy, fetal organs and nervous system are in the stage of differentiation and development, so we should be highly alert to the occurrence of congenital developmental abnormalities. Not many people are malnourished, but many people are overnourished. The birth rate of macrosomia has increased, which has increased the rate of caesarean section and dystocia. Due to the increase of dystocia, the birth rate of disabled children has increased, which has also planted seeds for adult diseases. In addition, although the number of malnourished pregnant women has decreased, malnutrition in a broad sense has increased, that is, unreasonable dietary structure, unbalanced nutritional components, lack of trace elements and macro elements or vitamins, impaired glucose tolerance and even gestational diabetes, and the incidence of iron deficiency anemia is still not low. Therefore, while strengthening nutrition, we should also pay attention to a reasonable diet. It's not that the more expensive and superior the food, the better. Don't be partial to food. Don't eat too carefully and don't eat too much processed food. Six types of women are prone to give birth to deformed children 1, and women with high fever in early pregnancy have high fever in early pregnancy. Even if the child has no obvious appearance abnormality, the development of brain tissue may be adversely affected, showing mental retardation and poor learning and reaction ability. This mental retardation is due to the death of fetal brain nerve cells caused by high fever, and the number of brain nerve cells is reduced. This kind of mental retardation cannot be recovered. Of course, fetal malformation caused by high fever is also related to the sensitivity of pregnant women to high fever and other factors. 2. Few pregnant women who are close to cats and dogs know that infected cats are also the source of infectious diseases that pose a great threat to fetal malformation, and cat feces are the main route of transmission of this malignant infectious disease. According to relevant data, about 40% of pregnant women in Britain are infected with cats, and about 500 babies are injured by cats every year. 3. Women who wear heavy makeup every day A survey in the United States shows that the incidence of fetal malformation in women who wear heavy makeup every day is 1.25 times that of those who do not wear heavy makeup. The adverse effects on fetal malformation are mainly toxic substances such as arsenic, lead and mercury contained in cosmetics. After being absorbed by pregnant women's skin and mucosa, these substances can penetrate the blood-fetal barrier and enter the fetal blood circulation, affecting the normal development of the fetus. Secondly, some ingredients in cosmetics will produce teratogenic aromatic amines after being irradiated by ultraviolet rays in the sun. 4. The mood of women who are nervous during pregnancy is controlled by the central nervous system and endocrine system, and adrenocortical hormone, one of the endocrine systems, is closely related to people's mood changes. When pregnant women are nervous, adrenocortical hormone may hinder the fusion of some embryonic tissues. If it happens in the first three months of pregnancy, it will cause fetal cleft lip or cleft palate and other deformities. 5. Female pregnant women drinking alcohol can enter the developing embryo through the placenta, causing serious damage to the fetus. Drinking more than 2 cups a day during pregnancy will have an impact on the fetus and even be dangerous; Drinking 2-4 cups a day is at risk of abnormal development. For example, the head is small, the ears and nose are small, and the upper lip is generous. 6. Female experts who ate food contaminated by mold pointed out that if pregnant women eat food contaminated by mycotoxin (moldy food), mycotoxin will harm the fetus through the placenta, causing cell chromosome breakage in the fetus.
