Abstract

Obesity is a leading global epidemic. Bariatric surgery is the only treatment demonstrating substantial long-term weight loss and medical benefits. However, there is limited research on the psychological outcomes following surgery. Therefore, the primary aim of this study was to systematically review depression, anxiety, and binge eating outcomes at different time points following bariatric surgery and identify whether bariatric surgery significantly reduces psychological symptoms over time. These outcomes were also examined among endoscopic bariatric procedures as a secondary aim. Forty-eight studies met inclusion criteria. Findings suggested that most patients experience a short-term reduction in anxiety and depression symptoms from pre-surgery. Over time, however, these symptoms increase and may even return to pre-surgery levels. Furthermore, while binge eating was uncommon after surgery, other disordered eating patterns may emerge. Binge eating may also restart over time as the stomach enlarges again. Overall, the complex psychological difficulties faced by individuals with obesity continue after surgery and may contribute to longer-term weight recidivism. More comprehensive and standardised psychological assessment procedures, including clinical interviews and longer-term follow-up, may provide insight into the psychological mechanisms maintaining weight management issues, and may serve as a starting point for improving the long-term success of patients with obesity.
