High-risk vs. low-risk pregnancies – OB-GYNs can manage high-risk or complicated pregnancies such as women who are expecting twins or have preexisting medical conditions. Midwives, on the other hand, can manage low-risk pregnancies and births, but can coordinate care with other specialists like OB-GYNs if necessary.

An obstetrician (OB) is a doctor who has special training in women's health and pregnancy. OB doctors specialize in both caring for women during pregnancy and labor and delivering their babies. Obstetrics involves care during pregnancy, childbirth, and the postpartum period. Gynecology deals with reproductive health and the functions and diseases specific to women and girls. What does OB/GYN stand for? It stands for obstetrician gynecologist, an expert on women's health who combines both specialties.
