The eating behavior disorders arise as a result of three factors: predisposing, precipitating and perpetuating. We must take into account the genetics and family history, dissatisfaction with body weight resulting in a restriction of diet and multi-disciplinary consequences of this disorder (physical, psychological and social) as perpetuating factors. We consider the coexistence of comorbidity between disordered eating behavior and personality disorders, mood disorders (depression) and disorders of impulse control.

Eating behavior disorders represent a major health problem that threatens the patient's life. Very important are the rapid detection of the same and the establishment of treatment. Treatment should be multidisciplinary with the patient and family, providing information on the approach to the patient, taking into account the lack of awareness of disease that often exists in patients.
