Obstetrics studies pregnancy, childbirth, and the postpartum period. It includes the care of both mother and baby throughout pregnancy, labour, and the puerperium (or immediately following birth). The word obstetrics comes from the Latin Ostara, meaning “to stand by”, as in “standing by to help”. Gynecology deals with women’s health, including their reproductive systems (Uterus, Ovaries, and Fallopian Tubes) and the general health of women and babies. An OBS Gynae is a doctor who specialises in Obstetrics & Gynaecology.
