title: Pain sensitivity in anorexia nervosa and bulimia nervosa.
abstract: Pain threshold was measured with short heat stimuli using a contact thermode in 19 patients with anorexia nervosa, 20 patients with bulimia nervosa, and 21 control subjects. Both patient groups had significantly elevated pain thresholds compared with the control subjects. In the total sample, no substantial covariation could be demonstrated among pain threshold and clinical, physiological, metabolic, or psychological data. However, in separate regression analyses pain threshold correlated significantly (negatively) with local skin temperature in the anorectic patients and almost significantly (positively) with body weight in the bulimic patients. This finding suggests that the reduced pain sensitivity in the two kinds of eating disorders might have different causes.
