What should you know about food allergy and itchy skin?

Food allergy may cause raised, itchy welts, flushing, or generalised itching. The skin reaction can occur with mouth symptoms, vomiting, cough, or breathing changes. Eczema, heat, contact irritation, medicines, and infections can also make skin itchy, so itching by itself does not establish the cause. A clinician will consider the food, timing, distribution, duration, and other symptoms when assessing Food Allergy.

Photograph visible hives before they fade and record the meal, packaged ingredients, timing, and symptoms. Avoid the suspected food until you receive personalised advice, but do not remove many foods without a nutrition plan. Use gentle, fragrance-free skin care for irritation. Do not test the food by eating it again at home. Ask about Allergy Testing if episodes recur or follow a consistent food pattern.

Call emergency services for itchy skin with trouble breathing, throat tightness, tongue or lip swelling, dizziness, collapse, or repeated vomiting. Use prescribed emergency treatment according to your plan. A rapid reaction involving several body areas can be Anaphylaxis, even if the skin findings later improve.

Do my skin changes look like hives or another rash? Which ingredients should I avoid? What should I do if I also develop an Itchy Throat? Do I need a written emergency plan?
