What’s the difference between a baby born at 37 weeks and 40 weeks? The following gap can not be compared

When it comes to giving birth to children, they all pay attention to “ripe fruits and good taste”, that is, when the fetus grows to full term, it will naturally start, so that the baby’s development will be better. However, there are some special cases, we can not wait for the fetus to start reproduction, but to “unload” in advance through caesarean section. < / P > < p > a friend of mine found that there was abnormal fetal position during pregnancy, and the doctor suggested cesarean section. Friends learned that the fetus to 37 weeks of gestation, even if it is full-term, would like to have a cesarean section at this time. However, her family told her that it was not good for the fetus to be dissected so early. Advised her to wait until 40 weeks, so that the fetus more complete development. < / P > < p > generally, after 37 weeks of gestation, it belongs to full-term pregnancy, but 37 weeks of pregnancy and 40 weeks of pregnancy, in different stages of pregnancy: 37 weeks of pregnancy + 0 to 38 weeks of pregnancy + 6 is early full-term pregnancy; 39 weeks + 0 to 40 weeks + 6 is full-term pregnancy; 41 weeks + 0 to 41 weeks + 6 is late term pregnancy. However, studies have shown that infants born at 37 weeks have higher risk factors in respiration, feeding, temperature control and infection than those born at 39 weeks. Therefore, a full-term baby is less risky and healthier than an early full-term pregnancy. That is: 40 weeks gestation is better than 37 weeks. < / P > < p > many older people say that “babies stay in their mothers’ stomachs for one day more than 10 days after birth”, which indicates that babies are more likely to grow in the womb, develop better and be born healthier. However, the weight of the baby born at 37 weeks of gestation is about 500g lighter than that at 40 weeks’ gestation. Because, 37 weeks of gestation, although the fetal organs are basically complete development, but after the body will enter the stage of long flesh. < / P > < p > we know that the lung is the latest development of all body organs in a baby. It’s still developing at 37 weeks. If the baby is born at this time, the lung function will be relatively weak, and the development of respiratory system will be significantly weaker than that of the baby born in 40 weeks. < / P > < p > the nervous system is the first part of fetal development, and the development process has been throughout the prenatal period. Therefore, the baby born at 37 weeks of gestation will obviously lag behind the baby born at 40 weeks in terms of nervous system development. Of course, in addition to these important development, the surface development of the two is also obvious. 40 weeks of gestation, the surface of the baby’s hair, fetal fat in the uterus will fall off part of itself, and the 37 week baby will not, so the baby born at 37 weeks of gestation will look a little dirtier than the baby born at 40 weeks of gestation. < / P > < p > since the baby born at 37 weeks is inferior to that born at 40 weeks in all aspects, is it possible that the longer the baby stays in the mother’s stomach, the better? In fact, it is not, because if you stay for more than 42 weeks, it belongs to overdue pregnancy, which can easily lead to weakened placental function, amniotic fluid turbidity, intrauterine hypoxia, and endanger the health of the baby. Moreover, it is possible that the fetus continues to grow and the skull hardens, leading to dystocia. < / P > < p > therefore, if the baby does not start after 40 weeks, pregnant mothers should not delay and go to the hospital in time. If the situation is abnormal, it is necessary to prepare for hasty delivery or caesarean section. Cai Shaofen stopped pregnancy for the first time. The 4 indexes on the B-ultrasound sheet in the early pregnancy were used to see whether the fetal development was good or not
