This dissertation consists of a theoretical - psychoanalytic analysis of anorexia with a focus on issues related to emotional maturation in the mother - baby relationship, as well as on issues involving trauma in psychic maturation. Firstly, we will conceptualize anorexia both in its pathological aspect and in the use of the disease as a way of maintaining oneself alive, in order to approach the Winnicotian concepts regarding the maternal primordial relationship with the anorexic individual. And finally, present the models of trauma through the Freudian bias. The present study deals with the psychic organization of the individuals compromised by anorexia, looking at the failures of the primordial object at an early moment of the psychic unfolding, as well as the individual s need to use the illness as a way to stay alive and try to separate from the external object.
