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.

How to treat chronic urticaria?

Chronic urticaria often utilizes antihistamine medications to control symptoms, combined with Traditional Chinese Medicine (TCM) and differential diagnosis and treatment. Treating chronic urticaria generally requires long-term use of antihistamines, sometimes for two or three months, or even up to six months, a year, or more. Typically, treatment involves the combination of two or more types of antihistamines. For cases of chronic urticaria where antihistamines are ineffective, immunosuppressants may be used to adjust the body’s immune state, thus controlling the outbreaks of chronic urticaria. Chronic urticaria is a long-term, slow process that cannot be resolved quickly, so it is important to try to identify the triggering factors of chronic urticaria, or to identify specific allergens. However, finding the allergen is usually challenging because many patients with chronic urticaria have conditions that are also related to their own immune status.

Urticaria is not contagious.

Urticaria is a hypersensitive skin disease related to the immune system, often occurring in patients with allergic constitutions. Urticaria is not contagious, so there is no need to worry about that. The causes of urticaria are mainly related to food, food additives, viral or bacterial infections, medications, and environmental factors such as climate and pollen. Therefore, if urticaria occurs, it is crucial to promptly identify the allergen and actively avoid triggers to prevent its occurrence. If urticaria does occur, it is essential to seek medical advice promptly.

How is urticaria caused?

There are many causes of hives, and the most common is related to genetics. If one of the parents has an allergic constitution, then the likelihood of allergies in their offspring significantly increases. Environmental factors also play a role in the occurrence of hives. For example, environments with a lot of dust or dust mites can trigger allergic reactions. Additionally, a humid living environment can promote the growth of fungi, which can also cause hives. The occurrence of hives is also related to food. Individuals who are allergic to proteins might experience hives when consuming high-protein foods like fish, shrimp, crabs, milk, and eggs. Furthermore, viral infections, bacterial infections, and parasite infections can also trigger hives.

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.
