Does Bariatric Binge-Eating Size Matter? Conceptual Model and Empirical Support

Area of Science:

• Bariatric Surgery
• Eating Disorders
• Psychopathology

Background:

• Bariatric surgery aims to limit food intake, but some patients experience loss of control (LOC) eating.
• Understanding different types of LOC eating post-surgery is crucial for effective treatment.

Purpose of the Study:

• To examine a novel classification system for binge eating and LOC eating in individuals who have undergone bariatric surgery.
• To differentiate between traditional binge eating, bariatric-specific objective binge eating, and bariatric-specific subjective binge eating.

Main Methods:

• A cross-sectional study involving 168 individuals who had bariatric surgery 6 months prior and reported LOC eating.
• Utilized the Eating Disorder Examination-Bariatric Surgery Version interview and self-report measures for depressive symptoms, functional impairment, and quality of life.
• Classified participants into three groups based on LOC eating episode characteristics: traditional objective binge, bariatric-objective binge, and bariatric-subjective binge.

Main Results:

• 75% of participants fell into the bariatric-objective binge episodes group, 10% into the traditional objective binge-eating group, and 15% into the bariatric-subjective binge episodes group.
• Significant differences were observed across the three groups in global eating disorder psychopathology, depressive symptoms, and functional impairment, showing a graded pattern related to binge size.
• No significant differences were found in quality of life among the groups.

Conclusions:

• The findings support a new classification system for binge/LOC eating following bariatric surgery.
• Binge size appears to be associated with distinct patterns of psychopathology in this population.
• Further longitudinal research is recommended to evaluate the impact of these classifications on clinical outcomes.
