Binge eating in bariatric surgery patients

Area of Science:

• Bariatric Surgery Research
• Obesity Studies
• Eating Behavior Analysis

Background:

• Morbid obesity presents significant health challenges requiring interventions like gastric bypass surgery.
• Understanding pre-operative eating behaviors and psychological factors is crucial for successful surgical outcomes.
• Previous research suggests a link between obesity, eating patterns, and psychological well-being.

Purpose of the Study:

• To assess eating behaviors, attitudes toward eating, body weight/shape, and depression in gastric bypass surgery candidates.
• To identify characteristics of binge eaters among individuals seeking bariatric surgery.
• To explore the relationship between binge eating and psychological factors in this population.

Main Methods:

• Utilized the Beck Depression Inventory (BDI), Three-Factor Eating Questionnaire (TFEQ), and Eating Disorder Examination (EDE).
• Administered assessments during the initial preoperative visit for 64 morbidly obese candidates.
• Compared eating behaviors and attitudes between binge eaters and non-binge eaters.

Main Results:

• 39% of candidates reported weekly binge eating episodes prior to treatment.
• Binge eaters demonstrated significantly higher scores on TFEQ Disinhibition and Hunger subscales.
• Significant differences were observed in attitudes toward eating, body shape, and weight between binge eaters and non-binge eaters.

Conclusions:

• A substantial proportion of gastric bypass surgery candidates exhibit binge eating behaviors.
• Binge eaters represent a distinct subgroup within the obese population, warranting targeted interventions.
• These findings support the need for comprehensive pre-surgical psychological and behavioral assessments.
