Dr. Robert Grayson is an obstetrician who also handles crisis situations for women in labor. A cesarean section is sometimes the necessary solution in a crisis. If the umbilical cord is being compressed, if the cord is around the baby's head and cutting off circulation, if the placenta detaches too suddenly, all of these situations and more can require a cesarean section.
There are other reasons for performing a cesarean section. For instance if the baby is too big to pass through its mother's pelvis, a cesarean section may be the only safe way to go. And many doctors will automatically plan for a cesarean section in the case of a mother who has had one before.
