An obstetrician is a medical doctor who specializes in pregnancy, childbirth, and the postpartum period. They provide care for women during pregnancy, monitor the health of both the mother and the baby, and assist in labor and delivery. Obstetricians are trained to handle various complications that may arise during pregnancy and childbirth. In addition to delivering babies, obstetricians also offer prenatal care, which includes regular check-ups, ultrasounds, and screenings. They may work closely with other healthcare professionals, such as midwives and pediatricians, to ensure comprehensive care for both mothers and their newborns.
