Although gynecology and obstetrics are closely related, they cover different medical fields. While gynecology mostly treats women of all ages that have various health issues, obstetrics deals with pregnant women and their health conditions. In many cases, doctors specialize in both fields and are trained for both professions. Your gynecologist will tell you from the start if they are experienced in both so you can find an obstetrician in case they aren’t. As a medical field that takes care of pregnant women, obstetrics covers pregnancy, childbirth, and the postpartum period.
