The authors, clinicians, and researchers in psychopathology, developed a trans-structural psychic phenomenon found in obese patients who have undergone bariatric surgery: fantasies and delusions of body fragmentation. The psychic impact of bariatric surgery was studied based on a clinical case of neurosis and another one of psychosis, highlighting an alteration of body image and its sensations which would be at the origin of this phenomenon of fragmentation.
