Russell’s sign is a physical indicator that may occur in people who engage in self-induced vomiting. People with Russell’s sign may have calluses, abrasions, or scars on the knuckles or back of their hands.
Russell’s sign is a physical symptom found in some people with eating disorders, such as bulimia nervosa. The abrasions can occur when someone repeatedly uses the fingers to induce vomiting, causing the skin on the knuckles to rub against the teeth.
However, other activities that cause friction against the back of the hand or knuckles can also lead to these calluses. Russell’s sign does not always indicate an eating disorder.
This article looks at the conditions that may cause Russell’s sign, including their symptoms and treatment, when to speak with a doctor, and how to get support with an eating disorder.
When a person inserts their fingers into their mouth and throat to trigger their gag reflex to induce vomiting, the skin on the knuckles or back of the hand rubs against the teeth.
Over time, this repeated action can cause damage to the skin, resulting in the formation of calluses, abrasions, or scars, collectively referred to as Russell’s sign.

Russell’s sign can indicate eating disorders, particularly bulimia nervosa and the binge-purge subtype of anorexia nervosa, as it often results from the repeated action of self-induced vomiting.
However, someone can have calluses or abrasions on their knuckles from other activities or conditions that cause repeated friction on the hands, such as certain types of manual labor or martial arts training.
While Russell’s sign is a strong indicator of self-induced vomiting and may raise suspicion of an eating disorder, it is not definitive proof. A thorough assessment by a healthcare professional is necessary for an accurate diagnosis.
People should speak with a doctor if they notice they experience symptoms of an eating disorder. Early intervention is
Eating disorders are complex mental health conditions that often require a multidisciplinary approach to treatment.
However, to treat Russell’s sign, doctors may suggest the following:
- soaking affected areas in warm water to soften the skin
- gently file calluses with a pumice stone
- apply moisturizer and lotion
- stop activities that cause friction on the hands and knuckles
In the United States, there are several organizations and places where people can seek support for eating disorders:
- National Eating Disorders Association (NEDA): NEDA provides support services, resources, and information on treatment options.
- Eating Disorder Hope: This organization offers recovery tools, information, and resources for those experiencing eating disorders. They also offer online support groups.
- National Association of Anorexia Nervosa and Associated Disorders (ANAD): ANAD offers support groups, recovery mentors, and other resources for people and families affected by eating disorders.
- FindTreatment.gov: This is a searchable database of treatment facilities provided by the Substance Abuse and Mental Health Services Administration (SAMHSA).
People should speak with a healthcare professional for personalized advice and treatment options. A doctor may be able to suggest local support groups and other resources.
Supporting someone with an eating disorder
It can be challenging for people with eating disorders to seek help or even acknowledge they have a problem. The following methods may help people offer support to someone with an eating disorder:
- Getting educated: People should learn as much as possible about eating disorders. People can offer better support when they understand the challenges a loved one is facing.
- Listening without judgment: Be a supportive listener and avoid making judgmental or critical comments about their appearance or eating habits.
- Expressing concerns: Express concerns honestly and kindly. Focus on their feelings and behaviors rather than their appearance.
- Encouraging professional help: Encourage them to seek help from a healthcare professional or support group. Offer to help them find a treatment center or accompany them to an appointment.
- Being patient: Recovery from an eating disorder is a long process, and there will be ups and downs. Be patient and offer support throughout their journey.
Not everyone with an eating disorder will develop Russell’s sign, and its presence does not definitively confirm an eating disorder.
However, Russell’s sign can indicate self-induced vomiting and may raise suspicion of an eating disorder, such as bulimia nervosa.
A thorough assessment by a healthcare professional is necessary for an accurate diagnosis and prompt treatment, which may include therapy or medications.
