Problematic Eating Behaviors and Eating Disorders Associated with Bariatric Surgery.

Bariatric surgery candidates often report problematic and/or eating disordered behaviors. For most patients, these eating behaviors improve after surgery. A subset, however, experience a recurrence or new onset of problematic eating behaviors as early as 2 months to 18 months after surgery, which can result in compromised weight loss/excessive weight regain. Those most at risk are individuals with comorbid psychopathology (ie, loss-of-control eating or depression) after surgery. For some, such problems are present before surgery. Therefore, it is critical to monitor patients closely after surgery so that appropriate psychiatric treatments can be provided if indicated.
