Purpose of review: Bariatric surgery has been consistently shown to be effective in long-term marked weight loss and in bringing significant improvement to medical comorbidities such as metabolic syndrome. Empirical data suggest a high prevalence of psychiatric disorders among bariatric surgery candidates. In this review, we focus on the studies published recently with a high impact on our understanding of the role of psychiatry in bariatric surgery.
Recent findings: This article reviews the specific psychopathologies before surgery, changes in psychopathologies after surgery, suicide risk related to bariatric surgery, factors associated with weight loss, and recommendations for presurgical and postsurgical assessment and management. Research indicates a decrease in certain psychiatric symptoms after weight loss with bariatric surgery. However, the risk of suicide and unsuccessful weight loss in some bariatric surgery patients make monitoring following surgery as important as careful assessment and management before surgery. Specific considerations for youth and older populations and future potential research foci are discussed.
Summary: Recent publications suggest new directions for psychiatric evaluation and interventions for bariatric surgery patients. Future research on outcomes of specific populations, effectiveness of psychopharmacotherapy, and underlying pathophysiology are warranted for the advancement of treating bariatric surgery patients.
