Bulimia nervosa is an eating disorder characterized by recurrent episodes of binge eating in combination with inappropriate compensatory behaviours (e.g., self-induced vomiting, laxative misuse).

Understanding the latest bulimia nervosa statistics is important for increasing awareness around the condition, especially as the condition is associated with profound medical, psychological, and social complications. Key statistics on bulimia nervosa are:

  1. The lifetime prevalence of bulimia nervosa for adult women ranges from 1.7%-2.0% and for men ranges from 0.5-0.7% 1Keski-Rahkonen A, Raevuori A, Hoek HW. Epidemiology of eating disorders: an update. Annual Review of Eating Disorders: CRC Press 2018:66-76..
