It is the wish of every parent to have a healthy baby, but sometimes things don’t go as planned. After ten months of pregnancy, parents are suffering and waiting for the baby. When they finally give birth, they end up with a strange baby. Some parents even high whistle God is unfair, is it really God’s unfair? In fact, we should not blame God and others, but ourselves. Medical research has found that there is a reason for the birth of strange fetuses. Women who are good at giving birth to strange fetuses mainly include: 1. Pregnant women with viral infections Viral infections during pregnancy, such as influenza virus, echovirus, coxsackievirus, measles virus, mumps virus, rubella virus and other infections, are the most common causes of malformed babies. Malformations can occur when the virus enters the mother’s body and acts on the fetus through the placenta. Common malformations include congenital cataracts, congenital heart disease, microcephaly or anencephaly, and dementia. Therefore, pregnant women should wear masks when they go out during the season or in areas where the virus is prevalent, and it is better not to go to public places to prevent viral infections. Pregnant women with viral infections, especially in the first three months, should be regular prenatal checkups, found deformed fetus, should be decisive termination of pregnancy. Clinical studies have found that women who have had high fever in early pregnancy, even if the child does not appear obvious appearance of deformity, but the brain tissue development may be adversely affected, manifested as mental retardation, learning and response ability is poor. This mental retardation is caused by the death of fetal brain nerve cells due to hyperthermia, which reduces the number of brain nerve cells, and this mental retardation cannot be recovered. Of course, high fever caused fetal malformation is also related to the sensitivity of pregnant women to high fever and other factors. 2, the habit of heavy makeup pregnant women According to a survey in the United States, the incidence of fetal malformations in people who wear heavy makeup every day is 1.25 times more than those who do not wear heavy makeup. Fetal malformation on the development of the adverse effects of the main cosmetics containing arsenic, lead, mercury and other toxic substances, these substances are absorbed by the skin and mucous membranes of pregnant women, can be through the blood-fetal barrier, into the fetal blood circulation, affecting the normal development of the fetus. Secondly, some of the ingredients in cosmetics by the sun’s ultraviolet radiation produces teratogenic aromatic amines compounds. 3, maternal malnutrition Clinical statistics show that each year in China, about 100,000 anencephalic children or vertebral cleft deformities born in the north than in the south, one of the reasons lies in the nutrition, especially the lack of folic acid. Inadequate intake of folic acid affects the closure of the neural tube of the fetus, resulting in a high incidence of children with cleft vertebrae. In addition, northern residents eat potatoes for a long time, potatoes are easy to germinate in the storage, germination to reach the potatoes containing lobelia, and lobelia will inhibit the neural tube closure of the fetus, which is also one of the reasons why pregnant women in the north are born with more deformed children. Women’s pregnancy, in addition to strengthening a variety of nutrients, but also should pay special attention to eat more green fresh vegetables, fruits, to supplement folic acid; pregnant women try to eat as little as possible potatoes, especially do not eat sprouted potatoes. 4.Pet-keeping pregnant women Few people know that the cat with bacteria is also a source of infectious diseases that lead to fetal malformation threat, and cat feces is the main way of spreading these malignant infectious diseases. According to relevant information, in the United Kingdom, due to pregnant women close to the cat to the baby caused by the adverse consequences of about 40% of the pregnant women infected with the disease, about 500 babies killed by cats every year. 5, drug-poisoned pregnant women have been found that a variety of drugs can cause fetal malformation, especially in the early stages of pregnancy (such as 4 weeks before) with drugs, the incidence of malformation is higher. This is because the fetus in this period of high sensitivity, is differentiation and joint stage, the system has not yet formed, so the most likely to occur drug poisoning. Common teratogenic drugs are antitumor drugs, antiepileptic drugs, glucocorticoid preparations, antidiabetic drugs, certain antibiotics, anti-allergy drugs, antithyroid drugs, analgesic or sedative drugs …… medication in early pregnancy (including traditional Chinese medicines) should be used under the guidance of a doctor, and should not be abused. The principle of medication is to be able to use a drug, not a combination of drugs; the dose of medication should be small, the course of treatment should be short, as far as possible, do not choose teratogenic drugs. 6, nervous pregnant women, human emotions by the central nervous and endocrine system control, one of the endocrine adrenocorticotropic hormone and human mood changes have a close relationship. Pregnant women emotional tension, adrenocorticotropic hormone may impede the embryo some of the tissues of the fusion effect, if it occurs in the first three months of pregnancy, will cause fetal cleft lip or palate and other malformations. 7, maternal placenta aging pregnant women Placenta aging is mostly seen in advanced age or overdue pregnancy. In recent years, clinical findings, repeated abortion, especially in the short-term repeated abortion, so that the uterine mucosa thinning and cause uterine mucosa repair. When pregnant again, the blood flow supplying the placenta decreases in the formation and development of the placenta, which affects the formation and development of the placenta. Placental development in turn directly affects the growth and development of the fetus. When the placenta is underdeveloped, the blood flow to the embryo and even to the fetus is reduced, and the fetus lacks nutrients, resulting in malformed babies. Married women of childbearing age, should take reliable contraceptive measures, minimize abortion; adolescent girls should eliminate premarital sex, in order to prevent future problems. 8, drinking pregnant women Pregnant women drinking alcohol, alcohol can enter the developing embryo through the placenta, serious damage to the fetus. If you drink more than 2 cups of alcohol a day during pregnancy, it can have an effect on the fetus and even be dangerous; if you drink 2-4 cups of alcohol a day, there is a risk of deformed development. Such as a very small head, very small ears and nose and wide upper lip and other deformities. 9, eat moldy food pregnant women Experts pointed out that pregnant women who eat contaminated by mycotoxin food or moldy food, mycotoxins can be through the placenta scourge of the fetus, resulting in fetal body cell chromosome breaks, causing fetal malformation. 10, other factors genetic factors, pregnant women exposed to toxic or harmful substances such as toxic metals, pesticides, chemicals, X-ray, pregnant women with diseases, such as sexually transmitted diseases, liver disease, diabetes, etc. can cause fetal malformation. Pregnant women should try to stay away from the corresponding teratogenic factors mentioned above.
