The primary duties of a physician include patient evaluation, diagnosis, and offering preventive care and proper treatment. They also come up with treatment plans, train assistants, educate patients and their families on medical conditions, and may also take up research and teaching works at medical colleges. Working in inpatient and outpatient settings, physicians are in direct contact with patients and their families, addressing their health and medical needs.
Physicians need to undertake a four-year undergraduate degree program, followed by a four-year in medical school. Then they will need to complete three to seven years of residency training. Once the education and training are done, they need to take up licensure and certification examinations approved by the authorized board to be able to practice. Based on any particular area of medicine such as bone, heart, skin, digestive system, etc., physicians can specialize further with advanced training.
