37 weeks and 40 weeks of pregnancy are both full term , so what is the difference between the two?

Babies born at 37 weeks of pregnancy may have lower resistance and are prone to colds, and babies born at term at 40 weeks have better resistance and are healthy and not easy to catch colds.

At the end of 37 weeks of pregnancy and the fetus weighs more than 2,500 grams, it can be considered full-term, but the baby born at this time is slightly weaker than the baby born after the 40th week, and the whole body system and nervous system of the baby born at 40 weeks of pregnancy will be more sound.

37 weeks then it must be that the child's nutrition still can't keep up, the immunity will be low, 40 weeks will definitely be the month of satisfaction, such a child is very healthy, and the immunity is also very strong.

1. First of all, there is a difference between 38 weeks and 40 weeks of babies, mainly in the development of digestive function, respiratory function and brain nerves. In general, a fetus born between 39 and 41 weeks is medically defined as a full-term baby. Full-term babies must be relatively well developed in the brain nerves, breathing, and digestion, which is what we call innate basic advantages.

Vice versa. 2. The baby who is 37 weeks pregnant should be classified as an early child, at this time, the baby's organ development and 40 weeks of the baby's respiratory and digestive functions will be relatively poor, and the only big difference is in the development of brain nerves. Data show that at 37 to 39 weeks, the brain nerves are the fastest developing period, and these cannot be compensated for by learning and training in the later environment.

The baby born after 40 weeks is closer to the due date, and the development of the fetus in all aspects should be more perfect. Therefore, the more pregnant mothers reach the age of pregnancy, the more they must be patient. At this time, the baby stays in his womb for one more day, and the baby's organ development will be more perfect.

After the baby is born, the family takes care of the baby, and the effort is also different for the baby born at about 38 weeks, because the weight is light and the height is relatively thin, the family may have to work more hard when taking care of it. The baby born after 40 weeks will basically weigh more than six pounds, or even seven or eight pounds, don't underestimate the baby's weight is so much, the family can save a lot of worry and effort when taking care of it. The difference between the baby's immunity and resistance, those who stay in the mother's womb for 40 weeks and then give birth to the baby, it can be said that the baby is very dominant in terms of resistance and immunity after birth.

In this way, the baby is in good health and is not easy to get sick, so it can be said that the baby suffers less, and adults do not need to worry too much. And those who have just been born at 38 weeks of the baby, in terms of resistance and immunity will be poor, just like the baby born less than 37 weeks may be sent to the incubator after birth, if the baby is just 38 weeks old, after the baby is born in a series of newborn examinations parents should also be more worried, after all, the baby was born half a month ahead of schedule, although the pregnant mothers are liberated, but the baby is good before the test results are not out of the mother's heart is also hanging.

There will be slight differences in the height and weight of the fetus, and the kidney function at 40 weeks is more mature at 40 weeks, and there is not much difference between 38 weeks and 40 weeks.

Text|Good pregnant sister.

A friend of mine was diagnosed with fetal malposition during pregnancy, and the doctor recommended a caesarean section. My friend learned that the fetus is considered full-term when it reaches 37 weeks of pregnancy, so I want to have a caesarean section at this time. However, her family told her that she could not be dissected so early, which was not good for fetal development.

Advise her to wait until 40 weeks so that the fetus is more fully developed.

Generally, after 37 weeks, it is a full-term pregnancy, but 37 weeks of pregnancy and 40 weeks of pregnancy are in different stages of pregnancy: 37 weeks of pregnancy + 0 to 38 weeks of pregnancy + 6 is an early term pregnancy; 39 weeks gestation +0 to 40 weeks gestation +6 is a complete term pregnancy; 41 weeks' gestation +0 to 41 weeks' gestation +6 is the third term pregnancy.

Studies have shown that babies born at 37 weeks have higher risk factors than babies born at 39 weeks in terms of breathing, feeding, body temperature control, infection, etc. Therefore, a full term pregnancy is less risky and healthier than an early full-term pregnancy. Namely:

It is better for a baby to be born at 40 weeks of pregnancy than to be born at 37 weeks.

The weight gap is significant

Many older generations say, "The baby stays in the mother's womb for 1 day, which is better than 10 days after birth", which means that the baby grows more in the womb, the development will be better, and the birth will be healthier. The baby born at 37 weeks of pregnancy is about 500g lighter than the baby born at 40 weeks of pregnancy, and the weight difference is still quite obvious. Because, although the organs of the fetus are basically fully developed at 37 weeks of pregnancy, the body will enter the stage of growing flesh after that.

There is a clear gap in the development of the respiratory system

We know that the lungs are the latest of all the body organs in your baby. It is usually at 37 weeks, still developing. If the baby is born at this time, the lung function will be relatively weak, and the respiratory system will be significantly weaker than the baby born at 40 weeks.

There is a significant gap in the development of the nervous system

The nervous system is the first part of the fetus to begin to develop, and the development process continues through the prenatal period. Therefore, babies born at 37 weeks of pregnancy will significantly lag behind babies born at 40 weeks of pregnancy in terms of neurological development.

Of course, in addition to these important developments, the surface development of the two is also obvious. At 40 weeks pregnant, part of the surface fetal hair and fetal fat will fall off in the uterus, while 37-week babies will not, so babies born at 37 weeks will look dirtier than babies born at 40 weeks.

Since the baby born at 37 weeks is at a disadvantage in all aspects compared to the baby born at 40 weeks, is it better for the baby to stay in the mother's womb for as long as possible? In fact, it is not, because if you stay for more than 42 weeks, it is an overdue pregnancy, which can easily lead to weakened placental function, turbid amniotic fluid, and intrauterine hypoxia, which endangers the baby's health. In addition, the fetus may continue to grow and the skull bone hardens, causing dystocia.

Therefore, if the baby does not start at 40 weeks, pregnant mothers should not delay it and go to the hospital for examination in time. If the situation is abnormal, it is time to be ready to induce labor or have a caesarean section.

Discussion: Pregnant mothers, how many weeks are you pregnant now? Can I have an early birth by caesarean section? 】

The same is a full-term baby, 37 weeks and 40 weeks born of the child is still very different, the general doctor will recommend that pregnant women go to the hospital to give birth at the expected date of delivery, although pregnancy is very hard, especially in the third trimester, because the belly is very large in the third trimester, whether it is sleeping or life is very inconvenient, so at this time many people are eager to go to the hospital for a caesarean section, some people will choose 37 weeks to cut the child down, but in fact, the baby is raised in the belly for a day, which is equivalent to a week of birth, Even if they are both full-term, there are many differences, so don't choose to have a caesarean section when your baby is 37 weeks old. <>

Generally, the fetus is full-term at 37 weeks, if the mother requires a caesarean section at this time, the doctor will also give you surgery, but in fact, the baby is born at 40 weeks is the best, if there is a red or other situation at 37 weeks, he has to do a caesarean section, because he is going to be born at 37 weeks, his lungs may not be fully developed, and those who stay in the mother's belly for 40 weeks baby, their lungs will be more complete. And even the crying will be extraordinarily loud, and the development of other organs of the fetus is also different, so don't rush to a caesarean section in order to unload the goods early, because this is not good for the growth and development of the fetus. <>

Some pregnant women give birth to babies at 37 weeks will actually weigh less, lighter weight babies are generally not good to feed, there will be a variety of problems in the body, some children will grow up and have poor physique, so if conditions permit, try to let the baby stay in the mother's belly for 40 weeks, some babies because of early delivery, so often gastrointestinal discomfort or decreased resistance, although the third trimester is very hard, but please expectant mothers must insist, Because the baby stays in the mother's womb for an extra day, it will be better for his development, but if the due date is exceeded, it is necessary to go to the hospital in time to give birth. <>

There will be a little difference, maybe the child born at 37 weeks is lighter, if the prenatal examination is normal, then the baby must be developing normally, under normal circumstances, the baby is born about a week before and after the expected date of delivery, and it is necessary to wait for the baby to start naturally and welcome the arrival of the baby.

It doesn't make any difference. Birth at term is the best, and the baby is the healthiest.

There is definitely a difference. A 37-week-old baby will be lower in height and weight than a 40-week-old baby. It is better to be born at 40 weeks, when the child's body is basically mature.

1. The difference in physical fitness, women enter the middle and late stages of pregnancy, nutrients mainly play a role in helping the baby's body improve its function, when it comes to physical fitness, if you look at external performance, it should be the most reflected in muscle strength. The longer the baby develops in the womb of the pregnant mother, the more nutrients will act on muscle growth and strengthen muscle strength, compared with the baby at 37 weeks, the baby at 40 weeks will show better physical fitness, such as fuller muscle tissue, stronger strength and so on.

2. In addition, the baby's health can also reflect the quality of the body, the baby is relatively fragile and has poor adaptability to the external environment, is susceptible to adverse effects, and has adverse reactions, while the 40-week baby is relatively mature in all aspects, especially the immune function, the baby can better adapt to the environment, and is naturally healthier.

3. The difference in cardiopulmonary function, the baby will cry when he is born, which means that the baby's lung function is turned on, and after the air enters the lungs normally, the baby's respiratory system will start to operate, and the crying sound will be very loud. The longer the baby is in the womb of the pregnant mother, the higher the maturity of all aspects of the body, including the cardiopulmonary function, and the greater the probability of loud crying after birth.

4. The difference in weight and body type, the longer the baby is in the womb of the pregnant mother, the more nutrients will act on the improvement of related functions, and weight and body shape are actually included. Through comparison, it is not difficult to find that the 37-week baby is obviously thinner than the 40-week baby, and the difference in weight can reflect the different levels of development of the baby. In the same pregnancy environment, the longer the pregnancy, the heavier the baby's weight and the higher the level of physical development.

5. It can be seen that there are still certain differences between full-term babies, but because the pregnancy life of each pregnant mother is not the same, and the development environment created for the fetus is also different, therefore, we do not rule out that some babies have developed relatively mature at 37 weeks and can be as healthy and worry-free as 40-week babies, but as long as it is naturally launched within the full-term range, it means that the baby is ready to be born.
