Anorexia Nervosa is a restrictive eating disorder diagnosis that has two subtypes, Anorexia Nervosa-Restricting Type and Anorexia Nervosa-Binge/Purge Type, that can occur alone or together. Though presentations vary among each individual, the DSM-V includes the following in its diagnostic criteria: a) Persistent restriction of energy intake, leading to low body weight or failure to meet growth trajectories, b) Intense fear of weight gain or becoming fat, and c) Disturbance in how the body is experienced or undue influence of shape and weight on self-evaluation. Anorexia Nervosa, as with all eating disorders, can impact those of all genders, sexes, race/ethnicities, sexual orientations, and ages. A common goal in treating Anorexia Nervosa is establishing consistent and appropriate nutritional intake as well exploring distortions around one’s body and weight.
