Common causes of urticaria: 1. Food: fish, shrimp, eggs, and milk are the most common, followed by certain meats and certain plant foods such as strawberries, cocoa, tomatoes, or garlic and other condiments. In addition, spoiled food decomposes into polypeptides, and alkaline polypeptides are histamine releasers. Protein foods are absorbed in the form of peptones or polypeptides before being completely digested, which can cause urticaria. This is more common in children and may also be due to the different permeability of the digestive tract mucosa in children and adults. In addition, coloring, flavoring, preservatives, and natural or synthetic substances added to food can also cause urticaria. 2. Inhalants: Various inhalants from the outside world may cause urticaria, such as various pollens, dust mites, cotton wool, animal fur, chemical gases, etc. may be the cause of urticaria. 3. Infection: Bacterial infection, viral infection, fungal infection and parasitic infection in the body can cause urticaria. In addition, papular urticaria may occur after bites from mosquitoes, mites, fleas, bedbugs, etc. These are common causes of urticaria. 4. Cholestatic urticaria: more common in young people aged 23 to 28 years old. The lesions are characterized by small wheals with a diameter of 1 to 3 mm, surrounded by red halos, which are sparsely distributed, not fused together, and cause severe itching.
