Purpose of Review

Individuals with morbid obesity benefit from bariatric surgery with respect to weight loss and decreases in obesity-related somatic disorders. This paper focuses on psychosocial outcomes and provides a narrative review of recent meta-analyses and controlled studies concerning postoperative depression and suicide.

Recent Findings

Considerable evidence shows short- and medium-term improvement in depressive symptoms after surgery. However, a subgroup of patients exhibits erosion of these improvements or new onset of depression in the long run. Some studies have found an increased risk for suicide among postoperative patients.


Prospective longitudinal examinations of factors contributing to the increased risk for postoperative depression and suicide and the interaction between these factors are warranted. The inclusion of mental health professionals in bariatric teams would help to monitor patients for negative psychosocial outcomes and to identify those patients who are vulnerable to depression, suicide, and any other forms of deliberated self-harm following surgery.

Ann Med. 2018;50(7):605–12. This is a large-scale 12-year cohort study from Taiwan that investigated the prevalence of major depressive disorder (MDD) in patients who received bariatric surgery. The findings suggest a higher risk of MDD in bariatric surgery recipients compared to controls, with patients who underwent malabsorptive procedures having a higher risk of MDD than those receiving restrictive procedures.PubMedGoogle Scholar
