According to wikipedia, The caesarean section is a surgical procedure in which incisions are made through a mother's abdomen (laparotomy) and uterus (hysterotomy) to deliver one or more babies. It is usually performed when a vaginal delivery would put the baby's or mother's life or health at risk, although in recent times it has been also performed upon request for childbirths that could otherwise have been natural. The World Health Organization (WHO) recommends that the rate of Caesarean sections should not exceed 15% in any country. The lower uterine segment section is the procedure most commonly used today involving a transverse cut just above the edge of the bladder and results in less blood loss and is easier to repair as well as minimal scarring.
It is important to remember that, with the exception of specific medical issues, a vaginal birth is healthier for both parent and child and a c-section is a serious surgery that can possibly result in complications and therefor the decision should not be made lightly.
