Atopic dermatitis, also known as eczema, is a chronic condition often linked to other allergic diseases like asthma.
Hives, or urticaria, are raised, itchy welts on the skin that can appear suddenly and last for hours or days.

Recognizing the symptoms of skin allergies can help in managing and treating them effectively. Symptoms can vary depending on the type of allergy.

Redness is a typical sign, indicating inflammation and irritation.
Itching can range from mild to severe, often leading to scratching and further irritation.

Causes of Skin Allergies

Understanding what triggers skin allergies can help in avoiding them and reducing flare-ups. Various factors can cause these reactions.

Pollen from trees, grasses, and weeds can cause allergic reactions when it comes into contact with the skin.
Animal dander from pets like cats and dogs can trigger skin allergies in sensitive individuals.
Certain foods, such as nuts, shellfish, and dairy, can cause allergic reactions that manifest on the skin.

Diagnosing Skin Allergies

Proper diagnosis is crucial for effective treatment. Several methods can help identify the specific allergen causing the reaction.

Patch testing involves applying small amounts of potential allergens to the skin to see if a reaction occurs.
Skin prick tests are used to identify immediate allergic reactions by pricking the skin with a small amount of allergen.
Blood tests can measure the immune system's response to specific allergens.
Elimination diets help identify food-related skin allergies by removing and reintroducing certain foods.
