In general, it is more appropriate to perform a cesarean section around 39 weeks of pregnancy, because at 39 weeks of pregnancy, the fetus is not only more mature in terms of body organs development, but also has relatively less possibility of developing diseases. Theoretically, it is considered that after 37 weeks of pregnancy the fetus is basically developed and can be delivered by cesarean section, but there are some special cases. Since pregnancy is counted from the last menstrual period, if the date of pregnancy is in the second half of the pregnancy month, the fetus is actually less than 37 weeks, its organs are not developed and it may not be able to withstand the external environment at a premature birth, which may lead to illness and premature death. If the patient decides to have a cesarean section, she should have an ultrasound to find out the actual maturity of the fetus and decide on the timing of the cesarean section based on her actual condition and the doctor’s recommendations. However, if there are symptoms such as abnormal amniotic fluid and fetal hypoxia, a cesarean section should be performed in time to avoid the occurrence of intrauterine asphyxia of the fetus. In addition, if there are special circumstances, such as a history of more than two cesarean deliveries, or if there is gestational diabetes or gestational hypertension and the condition is serious enough to require an early end to the pregnancy, it may also be performed earlier after weighing the pros and cons. After cesarean delivery, patients should turn more often to promote intestinal peristalsis and speed up exhaustion to avoid intestinal adhesions and other conditions. In addition, patients should enhance nutrition and consume more protein-rich foods, such as egg custard, to promote wound recovery.
