What is urticaria commonly characterized by?

  1. Skin discoloration

  2. The eruption of wheals or hives

  3. Dry, peeling skin

  4. Excessive hair growth

The correct answer is: The eruption of wheals or hives

Urticaria, commonly known as hives, is characterized by the eruption of wheals or hives on the skin. These hives are raised, itchy areas that can vary in size and often appear suddenly as a result of an allergic reaction or stimulus. The condition is typically associated with the release of histamine and other chemicals from the body, which leads to the inflammation and swelling that manifests as wheals. This response often indicates an underlying allergy or sensitivity, making it important for individuals experiencing such symptoms to monitor potential triggers. The other options, such as skin discoloration, dry peeling skin, and excessive hair growth, are not related to urticaria and signify different dermatological conditions.
