BACKGROUND: In recent decades, several longitudinal studies show the efficacy of bariatric surgery on long-term weight control and reductions in mortality due to clinical complications associated with obesity. However, studies also show significantly increased mortality due to suicide and impulsive behavior, for reasons largely unknown, which demonstrates the paucity of information concerning the clinical management of bariatric patients. This study aims to synthesize the current state of knowledge regarding the psychiatric care of bariatric patients. METHOD: A selective review of literature involving articles indexed on Medline and PubMed up to June 2010, using the terms: bariatric surgery, psychiatry, binge eating, follow-up, and outcome. RESULTS: The literature is somehow consensual in which there is no absolute psychiatric contraindication for bariatric surgery, although the preoperative evaluation is of extreme importance for the diagnosis and treatment of any psychiatric disorder, to assure adherence to the multidisciplinary approach, improved quality of life and possibly a better prognosis after surgery. Among the most prevalent disorders in this population is the binge-eating disorder (BED), which is associated with lower weight loss and poor quality of life, especially when present in the postoperative period. In the postoperative follow-up one should also be alert to the emergence of impulsive symptoms, including abuse of alcohol and other substances. DISCUSSION: Several studies indicate high prevalence of mental disorders and psychopathology in the population of bariatric patients. Although most patients experience adequate weight control and improved quality of life in the medium and long term, some patients develop abnormal behavior relating to dysfunctional eating patterns, abuse of alcohol and other substances, and complications associated with impulsive behavior, which suggests etiological hypotheses involving from neurochemistry to psychosocial theories. For all these reasons, it is of fundamental importance that mental health professionals to integrate the teams that evaluate and monitor the bariatric patients.
