anorexia (an″o-rek´se-ә)   lack or loss of appetite; 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 subjectively unpleasant food, surroundings, or company, or emotional states such as anxiety, irritation, anger, or fear; it may also be a symptom of a physical disorder or emotional disturbance.
