Abstract
BACKGROUND: Bariatric surgery is an effective treatment for severe obesity; however, high rates of psychiatric comorbidity complicate bariatric surgery care. As a result, importance has been placed on the need for ongoing psychiatric support in patients undergoing bariatric surgery. Given the lack of conclusive presurgery psychosocial predictors of postoperative mental health outcomes, studies have now shifted their focus to understand the long-term psychosocial sequalae that arise after surgery. Increasing evidence has demonstrated the potential for psychiatric care to stabilize psychiatric symptoms and minimize patient distress. OBJECTIVE: To review psychopharmacological and psychological interventions for patients undergoing bariatric surgery and their impact on mental health and weight outcomes after surgery. METHODS: We performed a comprehensive literature search in Ovid MEDLINE for studies examining the impact of psychopharmacological and psychological treatments on bariatric patients' postoperative mental health and weight outcomes. RESULTS: Overall, 37 studies were included in the review. Preliminary evidence suggests that psychiatric medications do not negatively impact weight loss or health-related quality of life in the short term; however, more rigorous research designs are needed. There are insufficient data on specific psychiatric medications and long-term impact on weight loss and psychosocial outcomes. Postoperative psychological interventions have evidence for improving eating psychopathology, anxiety, and depressive symptoms; however, effects on weight loss remain unclear. CONCLUSION: Evidence for psychopharmacological and psychological treatments remains preliminary. Consideration should be given to integrated, stepped-care models to provide personalized psychiatric interventions after surgery. Future research on expanding current psychiatric interventions, timing of delivery, and predictors of response is needed.
