anorexia

lack or loss of appetite for food. Appetite is psychological, dependent on memory and associations, as compared with hunger, which is physiologically aroused by the body's need for food. Anorexia can be brought about by unattractive food, surroundings, or the presence of other animals. The existence of appetite in animals is assumed. For strictest accuracy the words aphagia, anophagia, etc. should be used but common usage includes anorexia, hyperorexia, etc. Called also inappetence.
