anorexia nervosa
Let an agent explain anorexia nervosa in general terms from clinical guidelines, describe diagnostic criteria, complications and treatment approaches, distinguish related presentations, and route anyone affected to emergency care or professional help first.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain anorexia nervosa in general terms from clinical guidelines, describe diagnostic criteria, complications and treatment approaches, distinguish related presentations, and route anyone affected to emergency care or professional help first.
An eating disorder characterised by restriction of food intake leading to low body weight, intense fear of gaining weight and a distorted perception of body weight or shape, with subtypes and related presentations such as atypical anorexia nervosa at normal weight, and terms such as anorexia athletica in sport and pregorexia in pregnancy used informally; anorexia nervosa affects people of all genders, has serious medical complications and one of the highest mortality rates of psychiatric conditions, and is treated with nutritional rehabilitation, psychotherapy and medical care.
