If the results of the prenatal examination are normal, why do the children still have congenital dis

Parents want to be able to give birth to a healthier baby, so at this time we must pay attention to our habits, if you really have bad habits, then you must change at this time, so as to provide a good growth environment for your children. The results of the prenatal examination are normal, but why do congenital diseases still exist after the child is born?

Parents want their babies to grow up healthily, in fact, this is also the wish of every parent, but some children will have a lot of problems after birth. Therefore, this point is also what many people are more worried about, because the pregnant woman also went to the hospital for a detailed physical examination, but found that her physical symptoms are relatively normal, but there will be certain problems after the child is born. It may be because the accuracy of this prenatal examination is not very large, and there are certain limitations in the prenatal examination, the accuracy rate is not 100%, and the prenatal examination will also be affected by many objective factors, so it will lead to inaccurate results.

The reason why babies have this kind of problem is actually difficult for many people to accept, and many people may also doubt the meaning of prenatal checkups. Everyone must go to the hospital for prenatal check-up before pregnancy, and when pregnant, they must also go to the hospital for prenatal check-up according to the specified time, so that problems will be found. The reason for this problem is actually related to many reasons, it may be because your child is born with certain defects, but these defects cannot be checked by instruments, so at this time you will find that children will have such diseases.

This is a good pregnant woman, you must pay attention to improving your physical fitness, and in your daily life, you must keep your emotions peaceful. Pregnant women should not be too nervous at this time, and do not have an emotional breakdown.

It is because sometimes the prenatal examination does not detect some lesions in the child, and there is also a developmental problem in the child's brain.

Because some diseases cannot be seen, for example, some children are congenital mental retardation, and this disease cannot be seen.

Because of the limitations of the problems that can be detected in the routine prenatal check-up, you should improve the items of the prenatal check-up to achieve a comprehensive check-up.

It may be because there is no special attention during the examination, and it is also because a lot of things are ignored, so this situation will occur, or it may be because you did not pay attention to your physical condition for a period of time before birth, so it will lead.

It may be because these symptoms of the child are relatively secret, and secondly, because many things are ignored during the examination, so such problems occur.

The results of the prenatal examination are normal, and the child will have congenital diseases because some diseases cannot be detected through the prenatal examination, such as chromosomal abnormalities or functional abnormalities and inherited metabolic diseases.

1. First trimester. Pregnant women need to do a pregnancy test at 10 to 12 weeks of pregnancy, so as to ensure whether there is a problem with fetal implantation, and the number of B ultrasound examinations must be reduced as much as possible during this time period, so as not to affect the development of the fetus. 2. Second trimester.

Pregnant women can go to the hospital for prenatal check-ups every 4 weeks to prevent diseases or fetal dysplasia during pregnancy. 3. Third trimester. Pregnant women should have a check-up every week from the beginning of pregnancy to 36 weeks to ensure that there will be no accidents before they go into labor and ensure that the fetus can be born smoothly.

1. B-ultrasound. Women must check B ultrasound 5 to 8 weeks after they are pregnant to rule out whether it is an ectopic pregnancy, and B ultrasound is also a very important item in the subsequent examination, because this examination can see the baby's situation in the womb, and can also see the baby's appearance through B ultrasound. 2. NT inspection.

NT examination is equivalent to a deformity examination, NT examination is generally in 11 weeks to 13 weeks of pregnancy plus 6 days of time is the most suitable examination time, generally speaking, the result is more than three millimeters is abnormal, if this happens, be sure to consult the doctor's opinion to see if further examination is done, such as non-invasive. 3. Glucose tolerance test. The glucose tolerance test is usually done at 24 to 28 weeks after pregnancy, because the glucose tolerance test can screen for gestational diabetes, and it needs to be fasted for 12 hours before the test, and a certain amount of sugar water must be drunk within the specified time.

All in all, prenatal check-up is very important for pregnant women, and the items to be examined at different times are also different, but not all prostate diseases can be detected through prenatal check-up, but even if this is the test, it must not be missed.

Because there are some hereditary diseases that are difficult to detect, although technology is very advanced now, these genetic diseases are difficult to detect, so you can only know when you are born.

It may be through heredity that there are some congenital diseases, which have a lot to do with parents, so you should know your parents' medical history.

Because when the child is in the womb, it is not developed, and there is a completely recessive disease, or it may be congenital inheritance, and there will be congenital diseases from generation to generation.

Many pregnant women have normal prenatal test results, for example, the hands and feet of the fetus are developed, and the fetal heart rate is also very healthy, but these children are detected to have congenital diseases after birth. This phenomenon is also very normal, after all, the prenatal examination can only see the surface of the fetus, can not see the internal situation of the fetus, if the fetus genes or chromosomes have mutations, then it is possible that the fetus suffers from some congenital diseases.

I feel that this situation is very normal, after all, the prenatal examination can only see a general situation, and cannot completely examine the fetus's body. I also watched a news before, that is, pregnant women have been doing regular prenatal checkups when they are pregnant, and the results of prenatal checkups are very normal, but the child has a hand disability after birth, that is, the fingers do not grow, and the whole hand is a small chirp. Then the doctor also gave a professional, saying that the prenatal examination could not see the condition of the fetus's hands, because the fetus's hands were tightly clenched, and it was not known whether his hands were fully developed.

Therefore, when doing prenatal checkups, we can choose a four-dimensional prenatal checkup, so that we can see more clearly, although it costs more, but it can also make the child's body healthier, so that pregnant women can rest assured that they will not give birth to a deformed child.

We need to know that congenital genetic diseases are inherited by couples, or there are chromosomal mutations in the fetus. This condition is caused by the couple's chromosomes or genes, so the couple should have a physical examination before pregnancy, so that they can know whether both parties have genetic diseases, and can also ensure the health of the child and not let the child have problems. Because a child with deformity or congenital disease is a heavy burden for the family, the family cannot completely take care of the child, nor can it take care of the child for a lifetime, which is very bad.

It is likely that it is caused by genetic factors, and the accuracy of prenatal examination is not 100%, which will be affected by many objective factors, so there is still the possibility of congenital diseases.

The main reason is that it is not particularly meticulous during the prenatal examination, and secondly, it is also because there are certain problems in the body and there are certain injuries.

It may be because of genetic reasons, someone in the family has such a disease, so the child has a high chance of getting the disease.

With the continuous development of social economy, in real life, we will encounter a variety of situations, especially about the normal prenatal examination after the child is born, there will be congenital diseases, which makes many parents very puzzled, why does this happen? In fact, the main reason why this happens is because it is a very common bed symptom in small children.

First of all, we must understand such a problem, that is, normal prenatal examination, in fact, can only help us screen for some congenital deficiency diseases, but in most cases, there may also be missed diagnosis, so we must combine the medical technology of Xiangying to better help us solve this problem. However, some babies themselves do cardiac color ultrasound, there are some problems that cannot be found, so it is normal for this scene to appear, but after birth, there are congenital diseases, and some babies, even after birth, slowly evolve into some congenital diseases, such as some heart diseases.

Therefore, for different situations, we must have different understandings, and we must also know that the impact of these conditions on our baby is very serious, we must better carry out related physical diseases and health examinations in our lives, only in this way can we better help our babies, if there are genetic diseases, then our current medical means are also very superb, we can do some genetic tests, which can help us to check our babies. Have you suffered from some genetic disorders related to genetic classes.

The baby is very important to our parents, so we must understand that even if the medical methods are particularly superb now, there are many problems that cannot be solved, so we must pay attention to these relevant precautions, only pay attention to these relevant precautions, can help us solve the relevant problems.

Because the prenatal examination can only see whether the child's limbs are developing normally, and cannot detect the congenital diseases inside the child's body.

It may be due to genetic factors, it may be caused by your bad lifestyle habits during pregnancy, chromosomal abnormalities.

This is because this disease is formed by a variety of reasons, and it needs to be detected through a detailed examination, and the results of the prenatal examination are not absolute, so there are errors, so after the child is born, there will also be congenital diseases.

The positive ** rate of Tang Sieve is only 3 (what does the positive ** rate mean?) That is, for every 100 Tang screens, only 3 babies are finally confirmed to have a problem), the positive rate of non-invasive DNA can be increased to 50 70, and sheep wear can be reached. At 6-8 weeks of gestation, determine whether it is an intrauterine pregnancy, (pregnancy may be intrauterine and extrauterine), determine the location of the embryo, exclude the scar site pregnancy after cesarean section, whether the embryo is alive, and whether the development is in line with the gestational age.

The natural incidence of congenital birth defects is between 5% and 6%, ranging from Down's syndrome, severe heart malformations, severe abnormal metabolic diseases, to polydactyly, cleft lip, pigmentation, etc., there are more than 7,000 known newborn birth defects, and our screening during pregnancy can only detect dozens of common ones, depending on whether the disease falls within the scope of the hospital's examination items. Moreover, the prenatal examination can only detect obvious defects, and the non-obvious ones may not be detected, and there should be a mark on the hospital's prenatal examination list, which does not mean that it is 100% normal, and only includes certain items. That's what my pregnancy check-up slip looks like.

In the process of pregnancy, pregnant mothers are on time to do prenatal check-ups, the results are also very normal, but when born it is found that the baby is cerebral palsy, in fact, it is normal in the process of prenatal check-up, but after birth, cerebral palsy or malformations and other diseases, in obstetrics is also a lot, many pregnant mothers have misunderstood the definition of prenatal check-up, but this year's research has found that cerebral palsy also has certain genetic factors. If there are people with epilepsy, cerebral palsy or mental retardation in close relatives, the probability of children suffering from cerebral palsy is slightly higher than that of ordinary people.

If you are infected with viruses such as toxoplasmosis, rubella virus, cytomegalovirus, herpes simplex virus and other pathogenic microorganisms during pregnancy. It can cause damage to the central nervous system of the fetus, cause microcephaly, brain dysplasia, etc., resulting in cerebral palsy.

Because the prenatal examination is not able to detect all the diseases, but it can be detected with a high probability, and there are also a small number of diseases that cannot be detected at all, and only know when they are born.

Not all fetuses with malformations can be detected by ultrasound, and congenital stupid babies or some minor malformations caused by chromosomal abnormalities cannot be detected by ultrasound.

By the time the fetus is 5 to 6 months old, hearing has developed, but there is no way to know whether the fetus has congenital hearing impairment.

The heart's atrial septum (known as foramen ovale) and arteriovenous catheters close gradually after birth, and although heart disease can be easily diagnosed at birth, it cannot be known before birth.

Of course, the purpose of prenatal examination is to give birth to a healthy baby, but although medical technology is becoming more and more developed and can avoid the occurrence of some congenital abnormalities in the baby, the current prenatal screening still inevitably has some blind spots, and some diseases are difficult to detect through prenatal examination.
