What foods should you eat with erythema nodosum?

Erythema nodosum causes tender nodules through inflammation in deeper skin. Food usually does not directly remove the nodules, and a severe elimination diet can make it harder to meet nutritional needs. Aim for regular meals containing vegetables or fruit, protein foods, whole grains or other tolerated carbohydrates, and sources of calcium. Drink enough fluid for your usual needs. If diarrhoea, abdominal pain, mouth ulcers, or weight loss are present, tell your clinician because these symptoms may point to an underlying condition rather than a food intolerance alone.

Choose foods you tolerate and enjoy, and keep a simple note of meals only if you suspect a repeated personal reaction. Avoid starting supplements or removing dairy, gluten, or several food groups without professional guidance. If pain or another illness reduces your appetite, try smaller meals and soft options. Nutrition supports general wellbeing but does not replace assessment or treatment of an infection, medicine reaction, or inflammatory illness. Your clinician may discuss medicines, including oral corticosteroid treatment, when appropriate: [Oral Corticosteroid Treatment](/treatments/medical-dermatology/oral-corticosteroid-therapy/).

Get medical advice promptly if you cannot keep fluids down, have persistent diarrhoea, blood in the stool, marked weakness, breathing difficulty, or rapidly worsening painful swelling. Seek urgent help for faintness or severe dehydration symptoms.

Do my digestive symptoms need assessment? Should I change any food or supplement? How can I maintain nutrition if appetite is low? Could my current medicines affect my skin reaction?
