The current research aims to study the psychic aspects of binge eating in subjects submitted to bariatric surgery based on psychoanalytic theory, as well as to develop a reflection on the influences exerted by the surgical procedure on eating disorders and compulsive behaviors. t Bariatric interventions are important components in the treatment of obesity, aiming to promote weight reduction and improve the clinical comorbidities associated with this condition. However, the bariatric procedure is not a treatment for binge eating and the research on the subject presents contradictory results, which evidences the need for further investigations on the subject. We propose a study based psychoanalytically to try to reflect on possible arrangements that would lead to fixation in the diet and body, psychic aspects of binge eating unattainable to the scalpel and physical reduction of the stomach. To do so, we contemplate the early stages of infant development, its most archaic phases, the early mother-baby relationship and the vicissitudes of the alimentary function inherent to the maternal function, always valuing the dialogue with the other areas of knowledge involved in the etiology and treatment of obesity and eating disorders. In this way, we intend to build a approach that takes into account the singularity of each subject hidden behind the weight of obesity and compulsive stereotyped action.
