RESUMEN
INTRODUCTION: In recent years, euthanasia has been decriminalized or legalized in several countries. The debate on whether to legalize such a practice is open in many places and is a topic that arouses great controversy. Euthanasia has been presented as a response to situations of advanced, incurable, or irreversible disease, or situations that cause intolerable suffering to the person. However, in recent years, the claim has been asserted that this practice does not have to be associated with such situations. It may happen that a person wants to die and asks for help to do so, even if they are not in a specific clinical situation (pathology or condition) but are experiencing advanced age or present 'vital fatigue'. AIM: The objective of this article is to critically analyse the concept 'vital fatigue': define its meaning, its characteristics, its causes, and its consequences in the debate around euthanasia. To do this, a critical review of the main discussions and arguments present in the literature is made. CONCLUSIONS: It is concluded that vital fatigue can be understood as a product or manifestation of an individualistic and productivistic vision of the human being, in which its relational nature and intrinsic value remain in the background. The loss of the meaning of life also influences him. Therefore, in the face of this phenomenon, the most guaranteeing and ethical option is -we believe-accompaniment and holistic care of the person that allows the causal factors to be modulated, without the need to resort to euthanasia.
