Information for Patients


Childbirth Problems

While childbirth usually goes well, complications can happen. They can cause a risk to the mother, baby, or both. Possible complications include

  • Preterm (premature) labor, when labor starts before 37 completed weeks of pregnancy
  • Problems with the umbilical cord
  • Problems with the position of the baby, such as breech, in which the baby is going to come out feet first
  • Birth injuries

For some of these problems, the baby may need to be delivered surgically by a Cesarean section.
