Final answer:
Urticaria is the medical term for hives, which are often associated with various allergic responses ranging from mild, localized reactions to severe systemic events like anaphylaxis. Identification and management of the underlying allergens are key to treatment.
Step-by-step explanation:
Urticaria is the medical term for hives, which are a common skin reaction to an allergen, infection, or stress. Hives are part of the body's allergic response and can be triggered by various factors such as localized and systemic anaphylaxis, seasonal allergies including hay fever, and food allergies to items like shellfish and peanuts. Hives present as red, itchy welts that can vary in size and shape. Sometimes, in allergic reactions, skin testing is used where a wheal and flare response indicates a positive allergic reaction. It is important for individuals experiencing hives, particularly if accompanied by more severe allergic symptoms such as difficulty breathing or swelling of the face and throat, to seek medical attention.
Allergic reactions can vary, from mild and localized reactions like hives to severe and potentially life-threatening cases of anaphylaxis. Effective management of allergic symptoms often requires identification of the allergens and appropriate medical treatment which can include antihistamines, immunosuppressants, or epinephrine in cases of anaphylaxis.
