This diagnosis is applied to a poorly defined group of patients.
It consists both of patients who simply fail to meet the diagnostic criteria of anorexia or bulimia nervosa, i.e. a normal weight anorexic (due to beginning anorexic behaviour from a heavier weight), as well as patients with distinct conditions. The latter group consists of patients who vomit when they are anxious or patients who are unable to swallow in public.
It is thought that this diagnosis may be applied to as many as 5% of the population.

In binge eating disorder the person engages in uncontrollable episodes of binge eating, but s/he does not use compensatory purging behaviours (1).

Most patients with BED can be successfully managed in primary care. Give patients, other family members and carers ongoing information and support, including self-help information. Evidence-based self-help programmes and/or medication with an antidepressant such as fluoxetine 60 mg daily are the treatment options (2).
If treatment is unsuccessful in primary care, consider direct referral for cognitive behaviour therapy if it is available, or for secondary care support via an eating disorders clinic, or the specialist psychiatric services, if the patient meets local referral criteria (2).
