Which pregnant women are prone to giving birth to babies with deformities?
What are the tests for fetal malformations? The baby is an important member of the family. The healthy growth of the baby is related to the happiness of the family. However, due to congenital defects, some children not only cannot grow up healthily, but also the family will bear a heavy financial burden because of the high cost of treatment. So how to avoid deformed babies? Below, the editor of Babao.com will talk about: Which pregnant women are prone to giving birth to deformed babies?
What are the tests for fetal malformations?
Which pregnant women are prone to giving birth to babies with malformations
1 Expectant mothers with large mood swings during pregnancy
Human mood is controlled by the central nervous system and the endocrine system. Adrenocortical hormone, one of the endocrine secretions, is closely related to changes in human mood. The mood of a pregnant woman will affect the baby, and the fetus is aware. When expectant mothers have severe mood swings, adrenocortical hormones may hinder the integration of certain tissues of the embryo. If this occurs in the first 3 months of pregnancy, malformations such as cleft lip or cleft palate may occur in the fetus.
2 Pregnant mothers who drink alcohol during pregnancy
Medical research has confirmed that drinking alcohol during pregnancy causes alcohol to enter the fetus through the placenta, directly causing toxic effects on the fetus. It slows down the development of the fetus and can cause malformations and defects of certain organs, such as small head, small eyes, short chin, flat and narrow brain, short body, and even malformations of the heart and limbs.
3 Expectant mothers with high fever in early pregnancy
Research has found that pregnant women infected with high fever diseases during pregnancy will affect fetal development to varying degrees. Therefore, in order to reduce the rate of birth defects, attention must be paid to avoiding infection with high fever diseases during pregnancy. If infected, it should be cooled or treated promptly. At the same time, you should also be wary of overheated hot water baths, which will also affect the normal development of the fetus. If you have a high fever during pregnancy, it is best to get checked out in time.
4 Expectant mothers who still wear makeup during pregnancy
According to a survey in the United States, the incidence rate of fetal malformation for those who wear heavy makeup every day is 1.25 times higher than that of those who do not wear heavy makeup. times. The main adverse effects on fetal abnormal development are arsenic, lead, mercury and other toxic substances contained in cosmetics. After being absorbed by the skin and mucous membranes of pregnant women, these substances can penetrate the blood-fetal barrier and enter the fetal blood circulation, affecting the fetal blood circulation. normal development. Secondly, some ingredients in cosmetics produce aromatic amine compounds that have teratogenic effects after being exposed to ultraviolet rays in sunlight.
5 Expectant mothers who do not supplement folic acid according to regulations
In order to maintain folic acid levels in the body, women preparing for pregnancy and during pregnancy need to supplement 0.4mg of folic acid every day to prevent fetal neural tube defects. Lack of folic acid in early pregnancy can cause stillbirth, miscarriage, brain and neural tube malformations, and can also lead to malformations of the eyes, lips, palate, gastrointestinal tract, cardiovascular, kidneys, bones and other organs.
6 Expectant mothers who are accompanied by cats and dogs during pregnancy
Cats and puppies are friends of mankind, and they are always around like relatives. Why does it bring such a disaster to pregnant mothers? This is because almost all mammals such as cats, rabbits, pigs and dogs are naturally infected with Toxoplasma gondii, and this protozoa can cause zoonotic parasitism. Insect diseases. Among them, kittens cause the highest infection rate. Pregnant women infected with Toxoplasma gondii are more likely to have miscarriage and fetal malformations, with the risk of malformations being nearly 20%.
Precautions to avoid babies with malformations
1. Avoid incest marriage
Marriage between close relatives will lead to the \”meeting\” of the common recessive disease-causing genes carried by both men and women in the family. This \”meeting\” can easily lead to the onset of the disease-causing gene and lead to deformities in offspring.
2. Strength against influenza viruses
Due to changes in the immune system, cardiovascular system, and respiratory system of pregnant mothers after pregnancy, they are more susceptible to influenza The invasion of the virus causes a series of obvious symptoms. If the pregnant mother is infected with the influenza virus and develops symptoms such as high fever in the early stages of pregnancy (0-3 months of pregnancy), it is very likely to cause malformations in the baby.
3. Do not get close to small animals frequently
If expectant mothers are accidentally exposed to parasites (such as Toxoplasma gondii) in pet feces, After infection is caused, it is very likely to cause the baby to be born blind, suffer from epilepsy, etc.
What are the tests for fetal malformations?
1. Fetal B-ultrasound
This is a common method for checking fetal malformations. Generally It is performed between 20 and 24 weeks of pregnancy. Through fetal B-ultrasound, various organs of the fetus can be seen. If the B-ultrasound finds severe fetal malformation at this time, an abortion should be carried out in time to avoid delaying the pregnancy until the third trimester and causing greater pain to the pregnant woman.
However, not all malformed fetuses can be detected with B-ultrasound.B-ultrasound cannot detect the stupid type or some minor deformities. In addition, there are some malformations that will not show up until the third trimester of pregnancy, so B-ultrasound testing at this time cannot detect fetal malformations. Moreover, due to the limited resolution of ultrasound and technical reasons, some malformations will be missed during ultrasound examination.
2. Fetal magnetic resonance examination
This is also one of the methods to check for fetal malformations. Magnetic resonance has broad prospects for application in obstetrics due to its characteristics of multi-position imaging, high soft tissue resolution, no radiation, and safety for the fetus. At present, fetal magnetic resonance examination has become an important verification and supplementary diagnostic method for fetal abnormalities found in ultrasound examination in prenatal diagnosis. In particular, it has outstanding performance in diagnosing fetal central nervous system abnormalities, such as identifying cerebral hemorrhage.
3. Interventional prenatal diagnosis
This examination method refers to the chromosomal analysis of fetal cells through amniocentesis, umbilical cord blood puncture and other techniques. Karyotype analysis and genetic testing to diagnose certain fetal congenital diseases.
Tips for pregnancy examinations
The examination time should be when pregnant women go to the hospital for examination around 20 weeks of pregnancy , it is best not to exceed 28 weeks.
Examination items include: observing the fetal nasolabial region and heart, most anatomical abnormalities and birth defects can be found, such as anencephaly, hydrocephalus, spina bifida, limb malformations, severe cleft lip and palate, congenital Heart disease, etc.
A three-dimensional color ultrasound performed around 24 weeks can clearly display the various parts of the fetus’ organs, understand the fetal growth and development, and observe whether there are deformities in the head, limbs and the general structure of each organ. In addition, fetal heart rate, blood pressure, etc. should be checked regularly.
