[Psychological preparation for gastric bypass surgery].

Bariatric surgery is one of the treatment of choice for morbidly obese patients. However some of them regain weight post-surgery. Psychological factors involved in weight regain have not been clearly identified yet. The Geneva University Hospitals offer patients a psychological preparation for gastric bypass. In order to evaluate this preparation, 22 patients completed questionnaires assessing depressive symptoms (BDI-II), anxiety symptoms (HAD), and the presence of eating disorders (EDI-2) before and after psychological treatment. The results showed a significant improvement of the following EDI-2 subscales: drive for thinness, bulimia, interpersonal distrust, asceticism and interoceptive awareness. These results highlight the importance of a psychological preparation before surgery.
