Which of the following is NOT a symptom of Bulimia Nervosa?

In the context of Bulimia Nervosa, the primary characteristics include cycles of binge eating followed by compensatory behaviors to prevent weight gain. Binge eating refers to consuming an excessive amount of food within a short period, and this is typically accompanied by feelings of loss of control. The compensatory behaviors, which are essential to the diagnosis of Bulimia Nervosa, include self-induced vomiting, misuse of laxatives, and excessive exercise.

The symptom "excessive binging without purging" does not fit within the diagnostic criteria for Bulimia Nervosa because, for a diagnosis to be made, there must be both binge eating and compensatory behaviors. Without purging, such behavior might be indicative of Binge Eating Disorder instead, where there is no engagement in compensatory behaviors following the binge episodes.

Thus, the correct answer highlights the distinction between the symptoms associated with Bulimia Nervosa and those aligned with other eating disorders, emphasizing the necessity of both components for the diagnosis of Bulimia.
