Eating Disorder

Eating disorders involve persistent eating-related symptoms that impair health or functioning, and cannot be identified from body size or one habit alone.

An eating disorder is a mental disorder characterized by a persistent disturbance in eating or eating-related behavior that meaningfully impairs physical health or psychosocial functioning. Eating disorders are not defined simply by body weight, food choice, or a temporary change in appetite. They involve recognizable patterns of symptoms that can affect nutrition, behavior, emotions, and daily life .1

Major diagnostic groups include anorexia nervosa, bulimia nervosa, binge-eating disorder, avoidant/restrictive food intake disorder, and several other specified or unspecified disorders. These conditions differ in their defining features. For example, recurrent binge eating is central to binge-eating disorder, while anorexia nervosa includes persistent restriction leading to significantly low body weight together with characteristic fears or behaviors related to weight gain .1

The term should also be distinguished from disordered eating. A person can have irregular, restrictive, or distressing eating behaviors without meeting diagnostic criteria for an eating disorder. Conversely, an eating disorder can occur across a wide range of body sizes and may not be apparent from appearance alone. Diagnosis depends on the pattern, severity, duration, and consequences of symptoms rather than on a single eating habit .1
