A physician, medical practitioner, medical doctor, or doctor is a medical professional who is concerned with promoting, maintaining, or restoring health through the study, diagnosis, and treatment of disease, injury, and other physical and mental impairments. Doctors are formally trained in medicine, meaning the treatment of disease through medication, medical procedure and sometimes surgery. Physicians spend more time in school and conduct deeper study of diseases.
Many physicians will identify specific diseases categories, types of patients and methods of treatment area or specialty that they have the most knowledge or interest in to pursue as a career. Others decide to provide general comprehensive medical care to individuals, families, and communities. Most medical practitioners work along side or under a physician’s orders.
