Physicians support and manage the health care of people of all ages. They take medical histories, perform physical examinations, conduct diagnostic tests, recommend and provide treatment, conduct research, and advise patients on their overall health and well-being. While there are many different types of physicians, they can usually be divided into three broad categories:
- Primary care physicians are the doctors patients usually visit most frequently. They treat a wide range of illnesses and regularly provide preventive care, and they also enjoy long-term relationships with their patients. Pediatricians, family practitioners and general internists are primary care physicians.
- Surgeons perform operations to treat diseases and repair injuries.
- Specialists have expertise related to specific diseases as well as body parts, organs, and systems. Cardiologists, oncologists, neurologists, and ophthalmologists are examples of specialists.
