What does a Doctor do?
Physicians work to care for patients in a variety of ways, from treating chronic illnesses to advising about preventative healthcare. While physician specialties might vary, the commonality across specialties is that physicians primarily work to diagnose and treat injuries and illnesses. They often do this by performing physical exams, taking medical histories, performing and interpreting diagnostic tests, and recommending a plan of treatment.
Physicians require a high level of education, which typically includes a bachelor's degree, a degree from a medical school, and an extended period of time in a residency program. In addition, all states require physicians to be licensed. Beyond licensure, many physicians take an additional test to become board certified in order to increase employment opportunities.
