Origin of anorexia nervosa
"emaciation as a result of severe emotional disturbance," coined 1873 by William W. Gull (1816-1890), who also proposed apepsia hysterica as a name for it. See anorexia.
A psychosomatic disorder in which the sufferer refuses to eat and undertakes activities (such as self-induced vomiting) to bring about extreme weight loss. Anorexia, which is also characterized by a distorted self-image, occurs most often in young women aged twelve to twenty-one and may result in death if medical treatment is not obtained. Treatment for anorexia often includes extensive counseling to reveal underlying emotional problems.
