Background: Bulimia nervosa (BN) and related eating disorders such as binge eating disorder are common. General practitioners can play a key role in the identification and management of BN and related eating disorders.
Objective: This article describes the presenting and associated features of BN and overviews evidence based treatment approaches.
Discussion: Key features are recurrent episodes of binge eating, extreme weight control behaviours and over concern about weight and shape issues. By definition people are not underweight. Risk factors include being from a western culture, obesity, exposure to a restrictive dieting environment and low self esteem. People are more likely to present asking for help in weight control or a physical problem secondary to the eating disorder. Evidenced based therapies with good outcomes in current use are cognitive behaviour therapy (in full or guided self help forms), high dose fluoxetine, and interpersonal psychotherapy. It is important to convey optimism about treatment efficacy and outcomes.
