Which sign is associated with self-induced vomiting in Bulimia Nervosa?

Russell's Sign is a specific indicator associated with self-induced vomiting in individuals with Bulimia Nervosa. This sign refers to the presence of calluses or abrasions on the dorsal aspect of the first and second knuckles, which develop as a result of recurrent forceful purging behaviors. Patients may use their fingers to induce vomiting intentionally, and the friction caused during this action can lead to these physical changes on the hands.

In the context of Bulimia Nervosa, this sign serves as a physical manifestation of the individual's eating disorder and highlights the often hidden struggles related to body image and eating behaviors. Identifying Russell's Sign can help healthcare professionals recognize patterns of eating disorders and engage in conversations with patients about their behaviors in a sensitive manner. This recognition is critical in providing appropriate care and interventions.
