The correct answer is: May be indicative of either anorexia or bulimia, depending on other symptoms.
Frequent purging behaviors, such as making oneself vomit and using laxatives, are commonly associated with bulimia nervosa. However, individuals with anorexia nervosa (specifically the binge-eating/purging type) may also engage in these behaviors. Therefore, it's important to consider other symptoms and behaviors to determine the specific eating disorder.
