The paper describes the physical and psychological symptoms of anorexia nervosa, treatment methods, and implications for the classroom. A rationale is offered for the predominance of upper-middle and upper class female adolescents in the anorectic population. Four models of treatment for the anorectic individual are considered: medical, psychodynamic, behavioral, and systems. The two predominant sub-types of anorexia nervosa (bulimic and restrictive) are explained; and characteristics of the "normal" family system versus the anorectic family system are considered. Hospitalization as a treatment is mentioned. Pointed out are flaws in existing research. Among the suggestions offered to teachers for dealing with anorectic students are: to provide a classroom environment that is consistent and clear in structure; to support students' individual needs and realistic abilities; and to act on student behaviors in an objective and appropriate manner. Tables listing characteristics of bulimic and restrictive anorectic patients, compiled from studies done in clinics and in psychiatric hospitals, are included. (SW)
