With the discoveries in the field of Complexity, many scientific disciplines have begun to make efforts to face the new challenges that presume that this situations affects them as much from the epistemological point of view as the ontological effect on the composition and behavior of the very subjects of this study. Medicine does not escape this current which emerges and has begun to give shape and content to 21th Century knowledge, as well as to scientific production. The present article examines the current epistemilogical situation within medicine and the impact that advances in the field of biology, chemistry, and physics have had on it. It exposes considerations that latin-american doctors are already making in terms of complexity and its incidence in interorganism, doctor-patient, mind-body, and individual-society-environment relationships. Finally, the authors proposethat given the present conditions, an advance in the field of medicine should occur within transdisciplinarity, in a way in which one can consider the form of interaction, knowledge production, and a new relationship with the object and its surroundings; all of which we wish to term Complex Medicine.
