Skin Hives And Allergies: Identifying Culprits And Solutions

Skin hives and allergies can be incredibly disruptive to one’s daily life, causing discomfort and often affecting mental well-being. In order to effectively manage these conditions, it is crucial to identify the culprits and explore suitable solutions. Below, we provide insights into the causes of skin hives and allergies, as well as evidence-based strategies for identifying triggers and finding relief.

What are skin hives and allergies?

Skin hives, medically known as urticaria¹, are raised, itchy welts on the skin. These welts can vary in size and shape and may appear suddenly or persist for extended periods. Allergies, on the other hand, occur when the immune system reacts to a foreign substance or allergen, triggering symptoms such as itching, swelling, and inflammation².

Common culprits

Several factors can contribute to the development of skin hives and allergies. Some of the most common culprits include:

1. Food allergens: Certain foods, such as nuts, shellfish, eggs, and dairy products, can trigger allergic reactions in susceptible individuals.

2. Environmental allergens: Pollen, dust mites, pet dander, and mould are examples of environmental allergens that can provoke allergic reactions.

3. Insect bites and stings: Insect venom from bees, wasps, and mosquitoes can cause localised allergic reactions, leading to skin hives and swelling.

4. Medications: Some medications, including antibiotics, nonsteroidal anti-inflammatory drugs (NSAIDs), and certain painkillers, may induce allergic reactions in certain individuals.

5. Chemical irritants: Exposure to harsh chemicals found in household cleaning products, cosmetics, and personal care items can trigger skin irritation and hives in sensitive individuals.

Identifying triggers

Identifying the specific triggers of skin hives and allergies is essential for effective management. Keeping a detailed diary of symptoms, activities, and exposures can help pinpoint potential culprits. Additionally, healthcare providers may recommend allergy testing³, such as skin prick tests or radioallergosorbent (RAST) blood tests, to identify specific allergens. Patch testing is also sometimes carried out to look for contactants that may give rise to urticaria.

Exploring solutions

Once triggers have been identified, it is important to explore suitable treatment options for managing allergies and skin hives. Here are some evidence-based strategies:

Avoidance: Whenever possible, avoid exposure to known allergens or triggers. This may involve making dietary changes, implementing allergen-proofing measures in the home, or using protective clothing to minimise contact with irritants.
Medications: Antihistamines can help alleviate symptoms of skin hives and allergies by blocking the release of histamine, a chemical involved in allergic reactions. Sometimes, a combination of a few types of antihistamines may be required when the hives are more extensive. In severe cases however, oral medications such as corticosteroids or immunomodulators may be necessary to control symptoms. Chronic idiopathic urticaria that is refractory to management with antihistamines may also be treated with a biologic injection known as Omalizumab.
Topical treatments: Calamine lotion, hydrocortisone cream, and oatmeal baths can provide temporary relief from itching and inflammation associated with skin hives.
Allergen immunotherapy: For individuals with severe allergies, allergen immunotherapy, also known as allergy shots, may be recommended. This treatment involves gradually exposing the individual to increasing doses of the allergen, helping to desensitise the immune system over time.
Lifestyle modifications: Adopting a healthy lifestyle, including regular exercise, stress management techniques, and a balanced diet, can help strengthen the immune system and reduce the frequency and severity of allergic reactions.

Conclusion

Skin hives and allergies can significantly impact the quality of life, but with proper identification of triggers and appropriate management strategies, individuals can find relief and lead happier, healthier lives. By avoiding known allergens, utilising medications and topical treatments, and making lifestyle modifications, it is possible to minimise the frequency and severity of allergic reactions. Consulting with a certified dermatologist from a dermatology clinic or allergist can provide personalised guidance and support in managing skin hives and allergies effectively.
