Hives avoidance is actually based on the specific type of hives. If the patient belongs to peptonic urticaria, he needs to avoid protein-based foods, especially seafood products and animal proteins, such as beef, lamb, chicken, eggs, milk, etc. If the patient does not belong to peptic urticaria, but rather cold urticaria, there is usually no obvious requirement for avoiding food, and there are no special requirements when consuming food. For patients with febrile urticaria, they should try to avoid eating hot and spicy foods such as spicy hot. For patients with skin scratching signs or pressure urticaria where a rash appears on scratching, there is also no obvious contraindication, as long as you usually pay attention and try to avoid external stimulation of the skin.
