They are consultants to other physicians in these areas and serve as primary care physicians for women. As obstetricians, they care for the woman when she is pregnant. They have been trained to care for both the mother and the unborn child during both normal and complicated pregnancies. As gynecologists they care for the woman when she is not pregnant and treat both medical and surgical illnesses as well as provide preventative care.
