Objectives
We explored the severity of binge eating, loss of control over eating, emotional eating, and night eating before bariatric surgery and annually for 3 years following surgery. We also assessed the impact of post-operative eating psychopathology on weight outcomes.
Methods
Eight hundred forty-four patients participated in this prospective cohort study. Demographic factors, self-report measures of eating pathology (BES, NEQ, EES, EDE-Q), and weights (kg) were collected pre-surgery and annually for 3 years after surgery.
Results
The severity of problematic eating behaviors decreased after surgery and remained lower than baseline throughout follow-up. An increase was noted in binge eating scores (change in mean score ± SD = 0.85 ± 4.71; p = 0.002), emotional eating scores (2.00 ± 13.63; p = 0.033), and loss of control eating scores (1.11 ± 7.01; p < 0.001) after the first post-operative year that continued to the third post-operative year. There was also an increase in night eating scores between 2 and 3 years post-surgery (2.52 ± 8.00; p = 0.01). Higher 1-year post-operative binge eating scores were a significant predictor of lower 2-year % total weight loss (β = − 0.39, confidence interval (CI) − 1.23, − 0.16, p = 0.012).
Conclusions
The severity of problematic eating behaviors decrease after bariatric surgery, but increase significantly between the first and third post-operative years. Binge Eating Scale score at 1 year post-surgery was the only significant predictor of reduced percent total weight loss at 2 years. Additional prospective studies with adequate power are required to assess the progression of these eating pathologies beyond 3 years and their impact on weight outcomes beyond 2 years.
