Vomiting remains a prevalent and potentially destructive symptom of eating disorders, with significant dental and medical morbidity. Our findings suggest that certain clinical and personality variables distinguish individuals with purging-type eating disorders who vomit from those who do not, although there were no marked differences in Axis I or II comorbidity. Specifically targeting treatment to decrease duration of exposure to this dangerous symptom continues to be an important clinical objective.

The function of laxative abuse may differ across individuals with eating disorders, alternatively serving as a method of purging and a form of self-harm.
