Abstract
The effect of intracellular glucopenia induced by 2-deoxy-D-glucose (2-DG) on changes in hunger ratings, blood glucose, plasms cortisol, and prolactin levels were examined in six female patients with primary anorexia nervosa, three patients with bulimia nervosa, and six age-and sex-matched volunteers. In the normal subjects, hunger ratings obtained by the linear visual analog technique increased significantly at 60 minutes after 2-DG infusion and remained elevated. In Patients with anorexia nervosa, however, hunger ratins paradoxically decreased significantly at 90 minutes. In normal subjects, the ingestion of a 20-minute lunch relieved hunger, but neither the anorexic patients nor bulimic patients felt satiety even after food intake. These results suggest that the perception of hunger induced by 2-DG in anorexia nervosa and that of satiety in anorexia nervosa and bulimia nervosa are disturbed.
