Anorexia Nervosa

• Restriction of energy intake relative to requirements leading to significantly lower body weight in the context of age, sex, developmental trajectory, and physical health.

• Intense fear of gaining weight or becoming fat, even though underweight.

• Disturbance in the way in which one's body weight or shape is experienced, undue influence of body weight or shape on self-evaluation, or denial of the seriousness of the current low body weight.

• Even if all the DSM-5 criteria for anorexia are not met, a serious eating disorder can still be present. Atypical anorexia includes those individuals who meet the criteria for anorexia but who are not underweight despite significant weight loss.
