According to the DSM-IV-TR, a person must display:

• Refusal to maintain weight at or above a minimally normal weight for age and height (e.g., weight loss leading to maintenance of body weight less than 85% of that expected; or failure to make expected weight gain during period of growth, leading to body weight less than 85% of that expected).
• Intense fear of gaining weight or becoming overweight|fat.
• 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.
• In females (women who have had their first menstrual period but have not yet experienced menopause) amenorrhea (the absence of at least three consecutive menstrual cycles).

There are two subtypes of Anorexia, according to the DSM-IV-TR. The first subtype is known as the Restrictive Type. Restrictive type defines a person with Anorexia as not regularly binge-eating or purging – using laxatives, diuretics or enemas. The second type is Binge-Eating or Purging Type. This type defines a patient as regularly binge-eating OR purging. the misuse of laxatives, diuretics, or enemas).

When a patient has a serious condition that requires hospitalization, the first focus of treatment is to gain weight. This may be achieved via residential programs. Depending on the state mental health law, involuntary commitment may be used. Most patients with Anorexia Nervosa are treated on an outpatient basis.

Psychotherapy is the prime method of treatment, including family therapy. There are non-profit and community groups that offer support and advice. Drug treatments have not been found to be particularly effective.
