ICD-11 code : 6B80;
Preferred Label : Anorexia Nervosa;
ICD-11 definition : Anorexia Nervosa is characterized by significantly low body weight for the individual's
height, age and developmental stage (body mass index (BMI) less than 18.5 kg/m2 in
adults and BMI-for-age under fifth percentile in children and adolescents) that is
not due to another health condition or to the unavailability of food. Low body weight
is accompanied by a persistent pattern of behaviours to prevent restoration of normal
weight, which may include behaviours aimed at reducing energy intake (restricted eating),
purging behaviours (e.g., self-induced vomiting, misuse of laxatives), and behaviours
aimed at increasing energy expenditure (e.g., excessive exercise), typically associated
with a fear of weight gain. Low body weight or shape is central to the person's self-evaluation
or is inaccurately perceived to be normal or even excessive.;
