INSIGHT

DSM-5 Diagnostic Core

  • Bulimia requires recurrent binge eating plus compensatory behaviors and distorted self-evaluation related to weight or shape.
  • The DSM-5 threshold is at least once weekly for three months to qualify for diagnosis.
ANECDOTE

McDonald's Example And OCD Comparison

  • Dr. Nygorgen gives a vivid example of binge eating: sitting in a car at McDonald's and eating six Big Macs.
  • He compares purging rituals to OCD-like behaviors that relieve anxiety after binges.

Typical Body Weight Profile

  • People with bulimia are often normal-weight or overweight, not typically obese, and may restrict between binges.
  • They avoid high-calorie foods to prevent triggering binges, so obesity and bulimia rarely overlap.
