Internal Medicine specialists (internists, general physicians) are doctors who provide comprehensive assessment, diagnosis, and care to adult patients. They are often the first specialist seen by patients who have non-specific or atypical symptoms, or complex conditions. They are skilled in managing medical problems in a holistic way, considering all psychosocial and medical factors to enhance the quality of life. An internist understands disease affecting most body systems, and values the continuing care of all patients. Accredited general physicians are trained in the subspecialties of internal medicine, including emergency medicine and critical care.
