Urticaria, also referred to as hives, is a dermatological condition distinguished by the abrupt development of elevated, crimson, and pruritic lesions or wheals on the body's surface. Variable in size and shape, these welts frequently resolve themselves within a brief time frame, usually within twenty-four hours. An allergic reaction to specific foods, medications, insect assaults, or other substances is the most common cause of urticaria. Furthermore, non-allergic stimuli including tension, infections, and exposure to extremely high temperatures may also elicit this response. Mast cells in the epidermis secrete histamine and additional chemicals, which give rise to the distinctive manifestations of inflammation, pruritus, and edema. Urticaria is typically not a life-threatening medical condition and is amenable to symptomatic treatment with antihistamines or other medications. Persisting symptoms for a duration exceeding six weeks are classified as chronic urticaria; further diagnostic evaluation may be necessary to ascertain the underlying cause. It is recommended that individuals with severe or persistent urticaria symptoms seek the assistance of a healthcare professional in order to obtain an accurate diagnosis and suitable course of treatment.
