Summary

Pre-surgery eating pathology, including binge eating, was common in bariatric patients and linked to cognitive distortions. However, it did not predict weight outcomes or later vomiting.

Area of Science:

  • Bariatric Surgery
  • Eating Disorders
  • Psychopathology

Background:

  • Eating pathology is prevalent in patients seeking bariatric surgery.
  • Understanding pre-surgical eating behaviors is crucial for predicting post-surgical outcomes.
  • The relationship between pre-surgical eating pathology and psychopathology requires further investigation.

Purpose of the Study:

  • To determine the prevalence of eating pathology before and after bariatric surgery.
  • To assess the association between pre-surgical eating pathology and psychopathology.
  • To evaluate the link between pre-surgical eating pathology and surgical outcomes.

Main Methods:

  • 116 patients were assessed pre-surgery and at an average 5.5-year follow-up.
  • Prevalence of binge eating, binge eating disorder, and night eating syndrome were recorded.

  • Associations with psychopathology and surgical outcomes (weight, vomiting) were analyzed.

    • Main Results:

    • 52% of patients reported pre-operative binge eating; 16% met binge eating disorder criteria; 10% had night eating syndrome.
    • All forms of pre-surgical eating pathology were significantly associated with cognitive distortions.
    • Post-operatively, 33% of patients vomited weekly, but pre-surgical pathology did not correlate with weight outcome or vomiting.

    Conclusions:

    • Post-operative vomiting may indicate failed binge attempts rather than purging.
    • Pre-surgical eating pathology is common and linked to cognitive distortions but not long-term outcomes.
    • Further research is needed to understand the nuances of eating behaviors and outcomes after bariatric surgery.
