title: Bipolar disorder symptoms in patients seeking bariatric surgery.
abstract: BACKGROUND
  Mood disorders are common among patients seeking bariatric surgery although little data exist regarding the prevalence of bipolar symptoms in this population and how they influence surgical outcomes. Our aim was to describe baseline rates of bipolar symptoms and their relationship to psychological factors and completing surgery in a sample of adults seeking bariatric surgery at an academic medical center.
  
  
  METHODS
  We retrospectively reviewed the relationship of bipolar symptoms to demographic characteristics, baseline weight, psychological factors, and bariatric surgery completion.
  
  
  RESULTS
  Nine hundred thirty-five patients completed the preoperative psychological evaluation. Six percent of the preoperative sample screened positive for symptoms of bipolar disorder. Patients with bipolar symptoms endorsed more robust psychopathology, trauma history, and problematic eating behaviors than patients without bipolar symptoms. Twenty-two percent of the patients with bipolar symptoms underwent bariatric surgery (n = 12), yet only 13 % were denied bariatric surgery for psychiatric reasons, suggesting that other variables may influence the completion of bariatric surgery for these patients.
  
  
  CONCLUSIONS
  Prevalence rates of bipolar symptoms may be greater in patients seeking bariatric surgery compared with the general population, and few patients with bipolar symptoms actually undergo bariatric surgery. Psychological factors differentiate patients with bipolar symptoms who undergo bariatric surgery vs those who do not.
