doctor
Quick Summary
Medicine is the practice concerned with maintaining health and preventing, alleviating, or curing disease. A doctor, or physician, is a person specially trained in healing human medical disorders. The term "doctor" originated in the Middle Ages and evolved to refer to those with advanced degrees, including medical professionals.1234
Since World War II, medical knowledge and technology have expanded rapidly, leading to increased specialization within medicine. Major specialties include internal medicine, surgery, pediatrics, and psychiatry, among others. Advances in fields like genetics, microbiology, and pharmacology have significantly improved disease understanding and treatment.5
Doctors in teaching hospitals have dual roles: caring for patients and educating students through lectures and ward rounds. The process of diagnosing a patient involves gathering medical history, conducting examinations, and ordering tests to identify the cause of illness, a process known as clinical decision making.67
