Anorexia nervosa (AN) is marked by low body weight and restrictive eating habits. Individuals with AN often report a fear of gaining weight or becoming fat. Many people with AN describe feeling isolated from other people and some will also engage in binge eating and/or purging. There are often medical complications from the dietary restriction that individuals with AN practice. AN can affect individuals of all ages, races/ethnicities, and both males and females.
The research for adults with AN has been limited, but the current best-practice guidelines recommend treatments such as interpersonal psychotherapy and supportive clinical management with involvement from a physician. For adolescents, Family-based Treatment (i.e., Maudsley approach) has been shown in a series of research studies to be the first-line treatment for AN. Another approach with scientific support is adolescent-focused therapy.
