Abstract

Introduction: Eating disorder is a common psychological complication following bariatric surgery and can adversely affect long-term weight outcomes. This study aimed to assess the prevalence of eating disorder and its association with weight loss outcomes in patients with a history of bariatric surgery. Methods and Materials: This cross-sectional study was conducted in Rasht during 2023–2024. A total of 350 patients with a history of bariatric surgery that had undergone the procedure at least one year prior to the study were included. Eating attitudes were assessed using the standardized Eating Attitudes Test (EAT-26). Total weight loss (%) was calculated based on pre-surgery and current body weight and weight regain was defined as gaining at least 5% of the lowest post-surgical weight. Data were analyzed using SPSS software. Mann–Whitney U and Chi-square tests (or Fisher’s exact test) were used to examine the associations between eating disorder status, demographic and weight-related outcomes. Results: Among 350 bariatric surgery patients, 23.1% showed signs of eating disorders, with anorexia nervosa (18.9%) being much more common than bulimia nervosa (0.3%). Although the weight regain did not differ significantly in patients with and without eating disorders (χ² = 0.022, p = 0.882), patients without eating disorders had a significantly greater total weight loss (p = 0.035). No significant association was found between total eating disorder score and age, sex, job status and education and type of surgery. Conclusion and Discussion: The results of the present study reveal a notable prevalence of eating disorderswhich is associated with reduced total weight loss. These findings underscore the importance of screening and managing eating disorders to improve long-term weight outcomes after surgery.Early identification and targeted interventions are crucial to enhance weight management and overall health after surgery.
