On the basis of nine-year compulsory education, I don't know why someone asks such a question. Then what can cause harelip and foot varus?
Rabbit lip is called cleft lip in medicine. It is also caused by many factors.
First, genetic factors
The patient with cleft lip is likely to have a family history, which means that if the fetus is found to have cleft lip, it is very likely that some of his relatives have this deformity. Genetic study of cleft lip belongs to the history of polygenic diseases.
Second, nutritional factors
Pregnant women lack various vitamins during pregnancy. Mainly lack of vitamin A, vitamin B2, folic acid, etc.
Third, the infection factors
Receiving virus infection in early pregnancy, such as rubella virus, can also affect embryonic development and lead to fetal abnormalities. If the uterus is damaged in the early pregnancy, such as incomplete induced abortion and unscientific drug abortion, it can also lead to fetal malformation.
Fourth, drug factors
Most drugs can enter the embryo through the placental barrier after entering the mother, and some drugs may cause fetal malformation. Therefore, if you need to take drugs during pregnancy, you must take them under the guidance of a doctor. Don't make your own decisions.
Five, alcohol and tobacco factors
Studies have shown that smoking in the first trimester, passive smoking, alcoholism and fetal cleft lip are much higher than those of women who do not like alcohol and tobacco. Therefore, quitting smoking and drinking must be done.
First, genetic factors
The same genetic factors play a vital role in the pathogenesis of varus. If parents have this disease, the incidence rate of children is 30%, and the risk rate of illness among close relatives is also increased.
Second, the development factors of the fetus itself
Abnormal neural development, muscle and bone development of the fetus itself can cause fetal varus.
Third, the influence of external factors
Environmental pollution, pesticide residues and other problems are becoming increasingly serious. More and more studies show that environmental pollution has a bad influence on fetal development. Studies have also shown that maternal smoking during pregnancy will also increase the chance of fetal foot varus.
Both "harelip" and varus pedis are caused by many factors, not by sleeping posture. You need to consult a prenatal diagnostician if you encounter such a problem.
Many pregnant women like to lie on their backs during pregnancy, so that the fetal movement will not be so frequent, but now doctors advocate lying on their sides, and pregnant women are worried that lying on their backs for a long time during pregnancy will lead to harelip in the fetus. In fact, this is nonsense.
1. In the early embryonic development of the fetus, especially in the fifth week, after the facial embryonic tissue bulges, the maxillary process and the middle nasal process will form a rabbit lip without normal fusion. If both sides are not fused, it is bilateral cleft lip.
2. Bad habits of pregnant women. Pregnant women have bad habits of smoking and drinking during pregnancy, or often inhale a lot of second-hand smoke at home, which leads to fetal facial deformity.
3. Family inheritance. If one of the husband and wife has cleft lip, it will lead to cleft lip in the fetus through genetic inheritance.
4. Teratogenic drugs or viral infections.
It can be seen that cleft lip is caused by abnormal fetal face in the early stage of embryonic development, and has no direct relationship with the sleeping position of pregnant women.
Fetal foot varus refers to the subluxation of the foot joint and the varus or adduction of the fetal foot.
During pregnancy, if pregnant women sleep in the wrong position, they often squeeze into the legs of the fetus, making the feet of the fetus unable to stretch naturally and being in an abnormal bending state for a long time, which will easily lead to the foot varus of the fetus.
After the baby was born, the doctor found a slight varus, saying that the leg of the fetus was often bent during pregnancy. Later, I thought about it. No wonder my baby kept kicking me when I was lying on my left and right.
If the baby's posture in the uterus is improper, it will lead to varus. After the baby is born, the mother often gives the baby a foot massage, which will gradually recover. If it is pathological varus, then it is necessary to go to the hospital for intervention.
After 20-24 weeks of pregnancy, the doctor can check out the fetal foot varus.
1. Pregnant women should not lie flat during pregnancy, so that pregnant women will have supine syndrome, which will also affect the oxygen absorption of the fetus and increase the burden on the waist of pregnant women.
2. Use pregnant women's pillows, which can relieve the pain of pregnant women and improve the quality of sleep.
3. Pregnant women can sleep in the left and right lateral positions during pregnancy. If the fetus kicks badly, then pregnant women need to adjust their sleeping position to avoid accidentally injuring the baby.
In fact, it is human nature to be afraid of causing harelip and varus during pregnancy, but this situation is basically impossible because of a sleeping position. If you want to know why I am so sure, please look down:
In medicine, it should be called cleft lip, which is a common congenital malformation in oral and maxillofacial region, and the incidence rate is about 1: 1000. The common causes of harelip are: first, the congenital malformation I mentioned just now is determined by genetic factors, and the incidence of direct or collateral harelip is relatively high; Second, it is caused by infection, drug factors, poor diet and other factors in the early pregnancy, and as you can see, it has nothing to do with sleeping position.
How to prevent harelip;
1. Pay attention to nutritional supplements, ensure the intake of folic acid, B vitamins, zinc and other trace elements, and pay attention to a balanced diet.
2. Pregnant mothers should keep a good mood and chat with their babies more.
3. Be sure to follow the doctor's advice when taking medicine, and don't take medicine casually.
4. Keep good living habits, go to bed early and get up early.
In medicine, congenital horseshoe foot deformity is generally caused by genetic factors, but it is also caused by abnormal fetal position in uterus, and fetal ectopia is generally not something you can decide by sleeping position.
Treatment: Most children are mild and generally do not need special treatment, so they should be reset as soon as possible after birth, and their prognosis is good, but relatively serious, they will have to wait until 1~3 years old for surgical treatment.
Although there are genetic factors and environmental factors, the proportion of genetic factors is still high, that is to say, if relatives and elders do not have harelip, the probability of harelip in their offspring is also very low, provided that the expectant mother keeps a good diet during pregnancy, without stress, and has nothing to do with sleeping position, so long as the expectant mother ensures her own comfort.
As long as you avoid partial eclipse during pregnancy, ensure the full intake of vitamins B, C, D, calcium, iron and phosphorus, maintain peace of mind, avoid mental stress, do not take anti-tumor drugs, anticonvulsants, histamine drugs, Keminjing and some sleeping pills for morning sickness, do not smoke or drink alcohol, and avoid contact with radiation and microwaves, there will be no problem.
In addition, the causes of the baby's foot varus are also divided into congenital and environmental influences. If there is congenital skeletal malformation, there is nothing anyone can do but wait until the baby is born to see how to arrange the operation. The environmental factor is that the baby's posture in the womb is abnormal, but there is nothing you can do about it in this case, and it is impossible to solve the problem by sleeping position. Therefore, it is better to calm your mind and check regularly. Seeing the baby's normal development may make you feel at ease.
I hope it helps you. I am Pang Junliang, director of surgery at Angel Children's Hospital. Please ask me questions about children's surgery.
As a professional obstetrician, I can definitely refute the rumor that supine position during pregnancy has nothing to do with harelip and varus. As for the supine position, it is quite terrible for some treasure mothers. The terrible thing is not that it will lead to any deformity, but that there will be supine hypotension. The so-called supine hypotension syndrome refers to the decrease of blood flow to the heart due to the increased uterus compressing the inferior vena cava, which leads to insufficient blood supply. This is harmful to Bao Ma and the baby, so in general, during pregnancy, the doctor will suggest a lateral position. Personally, I don't advocate a left lateral position, as long as the left and right sides are comfortable.
As for the causes of harelip and varus pedis, I checked the fetal data, and found that harelip is mainly related to single gene and bad lifestyle. However, the cause of varus is still unclear. But no matter how you think about it, it can't be related to supine position.
To sum up, supine position during pregnancy is related to rabbit lips and varus, so don't be confused by Chinese and pseudo-popular science, or even rumors. Wish you a good pregnancy.
Pregnancy will bring great inconvenience to pregnant women in their actions, such as how to sleep. Now many pregnant women like to sleep on their backs. As far as sleeping posture is concerned, doctors advocate pregnant women to sleep on their sides. Many pregnant women are worried that sleeping on their backs will cause harelip and foot varus. Will these problems occur? Next, I will take you to know.
1, don't eat rabbit meat during pregnancy.
In China, most people have such an idea about eating, that is, they can make up for what they eat, but in fact there are some misleading ideas. The older generation said that you can't eat rabbit meat during pregnancy to avoid the baby's rabbit lips. In fact, there is no connection between the two. Rabbit meat contains a variety of extremely rich nutrients and pregnant women can eat it.
2, can't eat snails during pregnancy.
In fact, whether you eat snails or not, the baby will drool for several months after birth, which is a normal physiological development process! Although snail meat tastes good, many pregnant mothers can't resist the temptation, but it is not recommended for pregnant mothers to eat snail meat, because there are a lot of parasites and bacteria in snail meat, and it is difficult to kill it when heated at high temperature, which will affect the development of placenta and lead to deformity, which is not conducive to the healthy growth of baby! And eating snail meat during pregnancy, the baby will drool, which is unfounded.
3. Pregnant women can't eat crabs
Abnormal fetal position is usually related to uterine dysplasia, abnormal umbilical cord, polyhydramnios and other factors, and has nothing to do with eating crabs. So can pregnant women eat crabs? Crab tastes salty and cold, but it has other effects of promoting blood circulation and removing blood stasis. Although it is beneficial to the body, it is best for pregnant women not to eat crabs, because crab meat is a high-protein and high-cholesterol food, which is not conducive to health.
Sleeping on your back during pregnancy will not cause fetal harelip and foot varus. These two kinds of physical deformities have their own reasons and have nothing to do with the sleeping position of pregnant women.
Rabbit lip (cleft lip and palate) is a kind of neural tube malformation, and the causes are related to inheritance genes, maternal endocrine, smoking and drinking, drug abuse and so on. The specific reasons are not clear at present.
Fetal entropion is a developmental problem of fetus, which is related to chromosome, calcium deficiency or vitamin D deficiency during pregnancy, bad habits of mother and environmental pollution. Pregnant mother's sleeping position is not enough to cause entropion.
Unless it is some extreme behavior, such as sleeping on your stomach for a long time, or often pressing your stomach with strong force, it may cause the problem of varus, and pregnant women will pay attention to it in all aspects. I don't think pregnant women should do this. Lying on their backs for a short time will not cause any harm to the fetus, but in the long run, the baby may suffer from hypoxia. It is best to sleep alternately on the left and right sides when sleeping.
Since becoming a mother, a woman's heart has been placed on her child. After pregnancy, she is worried about the baby's development in the stomach, and she is also worried about whether the baby will be deformed. For example, some people ask, will lying on the back of pregnant women cause fetal harelip and foot varus?
It's really unnecessary to worry like this, because the two points have nothing to do.
1, in most cases, the fetus has rabbit lips because there are similar deformities in direct or collateral relatives. That is, because of genetic factors.
2. If the expectant mother is infected with a virus, such as influenza and rubella, or suffers some kind of damage when she is about two months pregnant, it will also cause the baby to vomit insects.
3. If the expectant mother is anemic or has diabetes during pregnancy, it will also lead to cleft lip in the fetus.
4. If the expectant mother has received a lot of X-ray exposure during pregnancy, affected by radiation, or the environment where the expectant mother lives is seriously polluted, the fetus will also have cleft lip.
5. If the expectant mother is particularly depressed in the first trimester, it may also lead to harelip in the fetus.
Under normal circumstances, the sleeping position of pregnant women will not affect the baby's foot varus. The baby's foot varus is mainly caused by the baby's relatively large size and relatively small uterus, which leads to the pressure of the fetus. There is also the legacy factor.
When you go for a checkup, many doctors will advise you to sleep on your left side. But in fact, we are all comfortable and sleep in life. So personally, I don't think it's too serious. If you sleep on your left side, feel uncomfortable and feel pressure on your heart, then adjust your sleeping position.
Lying on your back during pregnancy will not cause varus and harelip. If you feel comfortable sleeping on your back, you can sleep on your back properly, which has little effect on your child.
However, as a pregnant woman, the sleeping posture is particular, such as not lying on your back in the second and third trimester of pregnancy and not sleeping on your stomach during the whole pregnancy. These two sleeping postures can affect the development of the fetus. It is reasonable to sleep on the side, and sleeping on the left side is the best sleeping posture. This position will not oppress the child and will not lead to difficulties in the supply of nutrients for the child.
In the first trimester of pregnancy (1-3 months), the fetus still lives in the maternal pelvic cavity, and the direct external pressure or self-pressure will not be very heavy, so the sleeping posture of pregnant women can be arbitrary, mainly taking comfortable positions, such as supine position and lateral position. The pregnant uterus begins to leave the pelvic cavity at 12 weeks, but generally by 20 weeks, the bottom of the uterus can be felt at the navel level, that is, the uterus really enters the abdominal cavity.
Therefore, experts suggest that pregnant women after 20 weeks of pregnancy must not lie flat at any time. Especially some high-risk patients, such as premature delivery, multiple births, macrosomia, obesity and other pregnant women.
Pay more attention when you are tired, because generally speaking, hypotension occurs within 3- 10 minutes after lying flat. If you fall asleep during this time, you may never wake up again.
The causes of varus include the following aspects:
1, congenital varus: foot varus has appeared during embryonic development;
2, acquired factors: disease leads to varus, such as neuromuscular damage, spinal cord damage;
3, trauma: all kinds of trauma, such as spinal cord trauma, thigh trauma can lead to nerve injury, foot muscle imbalance, leading to varus.
What is the cause of rabbit lip?
1, genetic factors
Most patients can also find deformities in their immediate family members. According to the survey, the incidence rate of cleft lip is 1.7%. If one parent has cleft lip, the incidence rate is as high as 2.6%-5.6%, which is 15 to 30 times higher than the natural incidence rate. If a healthy parent already has a baby with cleft lip, the probability of the second baby having cleft lip is 4%.
2. Nutritional factors
Female friends always vomit or have a partial eclipse during pregnancy, which will affect the intake of nutrients and lead to vitamin deficiency. If vitamins are lacking for a long time, cleft lip and palate will occur.
3. Virus infection
If you encounter rubella virus infection during pregnancy, the probability of cleft lip and palate will increase. Drug factors, some drugs will affect the development of the embryo through the placenta, such as sleeping pills or anti-allergic drugs, may lead to fetal malformation.
Can lying on your back during pregnancy cause harelip and foot varus?
Rabbit lip and foot varus are caused by exposure to some harmful substances during fetal development, which leads to developmental problems, and has nothing to do with the posture during pregnancy.
If these two are related to the position during pregnancy, almost every child has defects. Which pregnant woman can guarantee that she has never been supine during pregnancy? Some pregnant women are worried that not paying attention to the sleeping position during pregnancy will have a great impact on the fetus. In fact, there is really no need to worry.
On the contrary, maintaining a posture for a long time is even more harmful. For example, some people say that it is good for the fetus to lie on the left side during pregnancy. The person who said this must have never been pregnant or experienced the process from pregnancy to birth.
In the early pregnancy, in fact, it doesn't matter what the lying position is. Some people even sleep on their stomach. In the third trimester, they sleep on their left side every time. Would you try it? In fact, whether lying on the left side or the right side, it is very uncomfortable for a long time. At this time, the supine position is more comfortable. Anyway, I always turn it over, except for not lying down.
However, in my experience, in the third trimester, after 38 weeks, the supine position is very uncomfortable, and I feel a little breathless with heavy things on my stomach. By this time, I basically lie on my left side and lie on my right side alternately.
Hello, there will be all kinds of worries during pregnancy. Some will be very wonderful, and there are all kinds of wonderful worries. For example, is there a relationship between supine and abnormal fetal development? The answer is no. It doesn't matter at all. I won't take the blame.
But what is the relationship between the occurrence of rabbit lips and what factors? It is related to psychological factors, drugs, infection, radiation, nutritional deficiency and genetic factors.
Tips: Rabbit lips are medically called cleft lip, which can be found by general B-ultrasound examination, but it is not very powerful, and it is not necessary to give up the child. You can do cosmetic repair after delivery.
