What is the main focus of the medical branch known as obstetrics?

The primary focus of obstetrics is on pregnancy and childbirth. This branch of medicine is dedicated to the health care of women during pregnancy, labor, and the postpartum period. It encompasses a wide range of care including prenatal check-ups, monitoring the growth and development of the fetus, managing complications during pregnancy, facilitating the delivery process, and providing postnatal care for both mother and baby. Obstetricians are specialized medical professionals trained to handle the complexities and potential complications associated with pregnancy and childbirth, ensuring the safety and health of both mother and child throughout these critical stages. Therefore, the emphasis on pregnancy and childbirth distinctly defines obstetrics from other medical practices that focus on various other health issues, making this the correct answer.
