Internists are medical specialists dedicated to global and comprehensive care for all of a person's illnesses, from adolescence to the end of life, coordinating between different professionals and doctors regarding a person's illness. As flexible specialists, we adapt our care work to the clinical aspects of the patient with the aim of improving quality of life in health or guiding their illness. We have the capacity to develop diagnostic reasoning with clinical judgment in each situation, based on the clinical history, physical examination, correctly indicating and interpreting the results of complementary examinations and prioritizing therapeutic options. The areas of interest of internal medicine are broad, performing tasks from outpatient consultation, hospitalized patients and critical care, with constantly updated training for the comprehensive investigation of non-surgical diseases.
