Two therapeutic approaches are contemplated

The pharmacological and the psychotherapeutic. Cognitive behavioral therapy has been very successful. It is very important that parents go to the doctor because patients often deny the symptoms and try to hide the seriousness of the problem.

Clinical diagnosis

Medical causes of loss of food control and vomiting should be ruled out in bulimia.

  • Diagnostic interview.
  • Rule out organic disease through: magnetic resonance imaging, general and specific tests and assessment by other specialists (endocrinologists).
  • Psychodiagnostic tests.
  • Carrying out the diagnosis following the ICD-10 and DSM-IV-TR criteria.

Treatment of bulimia nervosa

  • The disappearance of binge eating and purgative behaviors.
  • The development of standard eating patterns.
  • The modification of dysfunctional attitudes and ideas regarding weight and body image.
  • The disappearance of the associated symptoms (mainly anxiety and depression).
  • Learning guidelines to create and maintain stable social relationships.
  • Relapse prevention.
  • In a team with different specialists, which is usually led by a psychiatrist or child psychiatrist, a plan for weight recovery and dietary and nutritional re-education should be made.
  • A very close follow-up is done so that the recovery of the weight is gradual, with frequent controls.
  • Diet problems that affect the patient are studied and improved, as well as factors that influence binge eating and vomiting (anxiety about school, problems with parents or friends).
  • In addition to the physical improvement of weight, diet and eating habits, a psychiatric treatment is carried out, which combines psychoeducation, individual psychotherapy, group psychotherapy and family therapy.

  • Precipitating factors: crisis situations, such as loss of affection or the start of a strict diet due to personal or bodily dissatisfaction.
  • Perpetuating factors: malnutrition clinic and associated affective clinic (anxiety, depression …)
