General Physicians are highly trained specialists who provide a range of non-surgical health care to adult patients. They care for difficult, serious or unusual medical problems and continue to see the patient until these problems have resolved or stabilised. Physicians examine patients; take medical histories; prescribe medications; and order, perform, and interpret diagnostic tests. They counsel patients on diet, hygiene, and preventive healthcare. Surgeons operate on patients to treat injuries, such as broken bones; diseases, such as cancerous tumors; and deformities, such as cleft palates.
