Bulimia nervosa (BN) is a severe, life-threatening eating disorder characterized by recurrent episodes of binge eating followed by self-induced vomiting or other purging methods (e.g., laxatives, diuretics, excessive exercise) to prevent weight gain. BN is rare in men compared to women. Etiology, treatment and information on the clinical appearance are limited in males patients with BN. A 23-year-old man with BN is discussed under the influence of his psychiatric illness and his childhood history in the light of the literature examining. In this study, general characteristics and treatment of BN in males are presented, emphasizing different features between genders.
