Obstetrics is the branch of medicine that focuses on the care of women during pregnancy, childbirth, and the postpartum period (after childbirth). Obstetricians are medical doctors who specialize in the management of pregnancy, labor, and delivery, as well as the associated complications that may arise during these processes.

Key aspects of obstetrics include prenatal care, which involves monitoring the health of both the pregnant woman and the developing fetus through regular check-ups, screenings, and tests. Obstetricians also provide guidance on nutrition, exercise, and lifestyle choices to ensure a healthy pregnancy outcome.
