Anorexia nervosa en boulimia nervosa. I. Diagnostiek en behandeling

Disturbed eating behaviour and disturbed body experience are important features for the differential diagnosis of eating disorders from other disorders.

Eating disorders occur mainly in young females. The one-year prevalence of anorexia nervosa is 0.4 and that of bulimia nervosa 1.5 among young females.

To motivate patients for treatment it is important to discuss physical problems and the high risk of severe complications with them. It is difficult to motivate patients for treatment, because anorexia nervosa patients deny their illness and bulimia nervosa patients are ashamed and hide their disturbed eating behaviour.

The treatment of anorexia nervosa consists of two partly overlapping phases: normalizing the eating pattern to improve weight restoration and psychotherapeutic treatment for underlying emotional problems. Family therapy is effective for patients younger than 18 years with a short duration of illness. Cognitive behaviour therapy is the most important form of treatment for bulimia nervosa.
