Obstetrics and gynaecology (OB/GYN) is a medical sub-specialty that encompasses two distinct yet interconnected fields: obstetrics, which focuses on pregnancy, childbirth, and postpartum care, and gynaecology, which addresses the health of the female reproductive system throughout a woman’s life. OB/GYN specialists provide comprehensive care, including routine examinations, family planning, and the management of reproductive health issues and complications during pregnancy.
