Is it better to have a natural birth or a cesarean section?

The health of the pregnant woman's body and fetus is very critical during the pregnancy process. In the late pregnancy, natural birth and cesarean section are the two more common methods of delivery. Generally speaking, natural birth may be better for the body, with less trauma and faster postpartum recovery. However, the conditions for natural birth are also required, and a physical examination is required before delivery.

Is natural birth or caesarean section better?

Normal delivery, that is, vaginal delivery, is also a natural process, with less trauma, less bleeding, and quick postpartum recovery. Early contact, early sucking, and early milk production can be achieved in the delivery room. Postpartum mothers have fewer complications and shorter hospitalization time. The opposite is true for cesarean sections. The mother takes a longer time to recover and is more likely to develop chronic abdominal pain and leave scars. If you get pregnant with a second child or have a miscarriage after giving birth, it can easily be dangerous. For babies, natural delivery is facilitated by the squeezing of the birth canal, which helps the newborn to establish breathing and reduces the incidence of respiratory tract infections. Based on clinical experience, most pregnant women prefer natural birth. But natural childbirth is conditional, especially in some crisis situations, cesarean section can ensure the safety of mother and child.

Whether to have a natural birth or a caesarean section depends on the doctor's advice based on the specific conditions of your baby, such as the condition of the placenta, the condition of the amniotic fluid, and other factors, such as uterine height, size of the birth canal, etc. Taken together. If all data is normal, it is recommended to have a natural birth.

The complications of vaginal delivery for mothers and newborns can be reduced by 2-5 times compared with cesarean section, and the incidence of neonatal respiratory diseases is also significantly reduced. The mother recovers quickly after surgery and there is no scar on the uterus, which is beneficial for future pregnancy and childbirth as well as for taking contraceptive measures. The benefit of cesarean section is that it avoids the pain of natural childbirth, but it is not desirable compared to the complications and sequelae it brings to mother and baby. Cesarean section can only be used as a remedial surgery for pathological factors of the mother and baby.
