RESUMO
OBJECTIVE: Data suggest that serotonin activity is reduced in women at normal weight who have bulimia nervosa. The authors tested whether acute perturbations in serotonin activity could alter short-term eating behavior and mood. METHOD: They examined the effect of acute tryptophan depletion in 10 women with and 10 women without bulimia nervosa. RESULTS: Women with bulimia nervosa exhibited an increase in caloric intake and mood irritability after acute tryptophan depletion. CONCLUSIONS: These results indicate that women with bulimia nervosa have an exaggerated or pathological response to transient alterations in serotonin activity.

After admission for weight restoration, restrictor anorectics (n = 17) gained significantly less weight than bulimic anorectics (n = 17) in a 30-day period. However, these groups had similar caloric intake. Severity of illness was found to be a predictor of rate of weight gain for restrictor anorectics, but not for bulimic anorectics.
