An obstetrician is a medical doctor who specializes in the care of pregnant women and their unborn babies during pregnancy, childbirth, and after delivery. They are trained to handle high-risk pregnancies and provide prenatal care, including regular checkups, ultrasounds, and tests to monitor the health of both mother and baby. During labor and delivery, an obstetrician is responsible for managing the process, providing pain relief, and ensuring a safe birth. After childbirth, they continue to provide postpartum care, addressing any medical concerns and helping new mothers recover from their deliveries.
