Bulimia nervosa and binge eating disorder are unique nosological entities. Both show a large variability related to its presentation and severity which involves different therapeutic approaches and the need to individualize the treatment, thus it is indispensable a multidisciplinary approach.

Patients with bulimia nervosa may suffer from malnutrition and deficiency states or even excess weight, while in binge eating disorders, it is common overweight or obesity, which determine other comorbidities. Many of the symptoms and complications are associated with compensatory behaviors.

There are many therapeutic tools available for the treatment of these patients. The nutritional approach contemplates the individualized dietary advice which guarantees an adequate nutritional state and nutritional education. Its objective is to facilitate the voluntary adoption of eating behaviors that promote health and allow the long-term modification of eating habits and the cessation of purgatory and bingeing behaviors.

Psychological support is a first-line treatment and it must address the frequent disorder of eating behavior and psychiatric comorbidities. Psychotropic drugs are effective and widely used although these drugs are not essential.

The management is carried out mainly at an outpatient level, being the day hospital useful in selected patients. Hospitalization should be reserved to correct serious somatic or psychiatric complications or as a measure to contain non-treatable conflict situations.

Most of the guidelines' recommendations are based on expert consensus, with little evidence which evaluates clinical results and cost-effectiveness.
