Yes, cuts and calluses across the top of finger joints can be physical signs of Bulimia Nervosa. These are commonly known as "Russell's sign" or "Russell's sign in bulimia."
Russell's sign is caused by the repetitive action of inducing vomiting, where a person uses their fingers to trigger their gag reflex. Over time, this can lead to skin irritation, cuts, and calluses on the knuckles or tops of the finger joints.
It is essential to recognize that Bulimia Nervosa is a serious eating disorder with both physical and psychological consequences. If you suspect someone might be struggling with bulimia or any other eating disorder, it is crucial to encourage them to seek professional help and support. Early intervention can significantly improve the chances of recovery.
