Quality of Life and Psychological Changes in Bariatric Surgery: An Observational Study.

Introduction: Candidates for bariatric surgery may have psychiatric disorders that must be evaluated. The aim of this study was to describe the psychological state and quality of life (QoL) of patients with obesity awaiting bariatric surgery prior to surgical procedure and 1 year after surgery.
Methods: A longitudinal retrospective observational study was carried out in 71 patients awaiting bariatric surgery. Anthropometric data were collected, and the following were evaluated before and 1 year after the intervention: 44 patients were evaluated to rule out personality disorder, using the Salamanca Questionnaire of Personality Disorders; eating disorder, with the Bulimia Test of Edinburgh (BITE); depression, using the Beck Depression Inventory (BDI); and 71 patients were evaluated QoL, with the "36-Item Short Form Health Survey" (SF-36).
Results: A total of 34.1% (n = 15) of patients presented personality disorder (group B most frequent). A total of 31.8% (n = 14) obtained scores suggesting anomalous food behavior (6.8%, n = 3 severe). According to the BDI, 43.2% (n = 19) showed low mood prior to the intervention. Lower scores were obtained when evaluating QoL for physical functioning (physical function: 56.81 ± 24.9; physical problems: 66.76 ± 37.64). One year after the intervention, QoL improved in those patients who underwent the sleeve gastrectomy (SG).
Conclusions: Patients with bariatric surgery more frequently presented with type B and C personalities. One year after bariatric surgery, an improvement in QoL test was observed. Patients who underwent SG technique showed better mean scores than those after biliopancreatic diversion.
