Artificial urticaria is a disease caused by allergies, and it is one of the more difficult types of urticaria to treat. This disease is not contagious and will not spread through contact with others. Once diagnosed with this disease, formal treatment is necessary, and one can visit the dermatology department of a standard hospital for oral antiallergic medication treatment. If the condition persists for a long time and the treatment effects are unsatisfactory, it might be helpful to check for allergens to ascertain what triggers the allergy. Common allergens often include diet, living environment, dust mites, or pollen. Therefore, during and after treatment, it is advisable to enhance physical exercise to boost immunity, avoid keeping pets, stay away from places with dense vegetation, and refrain from consuming spicy and stimulating foods.

What should not be eaten with hives?

Patients with urticaria have individual differences in their physical constitutions, and not everyone is allergic to the same foods. However, some foods have a higher likelihood of causing allergies, such as seafood, shrimp, crabs, silkworm pupae, beef, lamb, dog meat, various exotic birds and game, fruits like mango, pineapple, durian, and lemon, as well as various food additives. Additionally, spicy and stimulating foods and alcoholic beverages can aggravate allergic reactions and should be avoided as much as possible. Patients who frequently suffer from urticaria may consider undergoing allergen testing to identify which foods trigger allergic reactions. However, the allergen doses used in tests are very small and many factors can affect the results, hence the test outcomes may not fully reflect the actual situation within the patient's body. Moreover, the variety of foods tested is limited, and foods not tested could still potentially trigger urticaria in patients.

How should hives be treated?

Urticaria is divided into acute and chronic types. Antihistamines are the first choice of treatment for acute urticaria. If the condition is severe and antihistamines are ineffective, corticosteroids can be used to control the condition. The fundamental treatment for chronic urticaria is to remove the cause, and specific medications should be used under the guidance of a doctor.

Characteristics of papular urticaria

Papular urticaria is a type of allergic reaction, generally associated with contact with irritants, or bites from mosquitoes and fleas. The likelihood of occurrence increases if small animals are kept at home. Typically, small red papules or red wheals appear on localized areas of the body or extensively, with a transparent blister on top. The itching is quite severe, and the blisters are prone to bursting when scratched. Once symptoms appear, it is crucial to treat them with proper medication, and care should be taken to prevent infection if the blisters are scratched open. To prevent recurrence, it is advisable not to keep small animals at home, to frequently disinfect clothes, sheets, and duvet covers by exposing them to sunlight to eliminate mites or fleas, and to maintain a standard diet and lifestyle habits.

How to Distinguish Between Papular Urticaria and Urticaria

Papular urticaria, also known as insect bite dermatitis, is a different disease from urticaria. Urticaria, also known as wheals, is called yinzhen in traditional Chinese medicine, and it is a localized edema of the skin and mucous membranes due to temporary increased vascular permeability. For most patients with urticaria, the exact cause cannot be identified. Common causes include foods, such as animal proteins and certain food additives that induce urticaria. Urticaria can also be triggered by certain infections as allergens, as well as by certain medications such as penicillin, serum products, various vaccines, sulfonamides, etc. Additionally, common inhalants such as pollen, animal dander, dust, fungal spores, dust mites, and volatile chemicals can also trigger urticaria. Papular urticaria is characterized by a small blister in the center of a reddish area, often resulting from bites or stings of various insects like mosquitoes, mites, bees, etc., or from irritation by toxic sap on the skin. Improvement can be seen once removed from the allergenic environment.
