A history of adjustment disorder predicts greater weight loss after sleeve gastrectomy


      • A previous diagnosis of adjustment disorder is predictive of a better surgical outcome.
      • Older patients have a higher probability of therapeutic failure after surgery.
      • The presence of diabetes predicts a poorer bariatric surgery outcome.
      • Respiratory problems predict a poorer bariatric surgery outcome.
      • The higher the body mass index, the poorer the results of bariatric surgery.



      Bariatric surgery is one of the most effective long-term options for treating class III obesity or class II obesity with medical co-morbidities; however, a significant number of patients do not achieve the expected weight loss. New studies are needed to find the predictive value of different variables on surgery outcomes.


      Our aim was to study a number of physical, medical, and psychopathological variables as potential risk factors for poor outcomes in patients with class II–IV obesity scheduled for sleeve gastrectomy.


      Sagrat Cor University Hospital in Barcelona, Spain.


      This prospective longitudinal study enrolled a sample consisting of 441 patients from whom a descriptive analysis was obtained. For 235 of them, we performed a comparative analysis between the patients with differing responses to sleeve gastrectomy after 1 year of follow-up. The remaining patients had differing follow-up data or were lost to follow-up. To collect the data, a semi-structured interview was conducted, and various tests were administered to assess the patients’ psychopathology (Hamilton Rating Scale for Depression, Hamilton Anxiety Rating Scale) and functionality (Global Assessment of Functioning Scale).


      The results show the prognostic relationship between certain presurgery variables and the good or poor outcomes of the bariatric surgery, based on the patients’ weight loss. Advanced age, high body mass index, diabetes, and respiratory problems were significant predictors of a poor response to surgery. Contrarywise, a history of adjustment disorder predicted a better response.


      The results allow us to conclude that, beyond well-established physical and medical conditions, a psychopathological study of patients prior to bariatric surgery including adjustment disorders could be predictive of therapeutic response and could help to personalize the follow-up.
