Urticaria, commonly known as hives, is a skin condition marked by red, raised, itchy welts that can appear anywhere on the body. These welts may last a few hours or days and often vanish without leaving a trace, though in some cases they reoccur and significantly affect quality of life.
Urticaria occurs when mast cells release histamine, causing fluid to leak from small blood vessels under the skin. The result is swelling and itching. Symptoms include:
-
Hives: Red or skin-colored welts, often with pale centers
-
Itching: Ranges from mild to severe
-
Evanescent nature: Welts usually disappear within 24 hours
-
Angioedema: Deep swelling in areas like the lips, hands, or eyelids, sometimes requiring emergency care
There are two main types:
-
Acute urticaria (under 6 weeks)
-
Chronic urticaria (longer than 6 weeks), often autoimmune in nature
Triggers can include allergies (foods, medications), infections, physical stimuli (cold, heat, pressure), and stress.
Treatment focuses on symptom relief:
-
Antihistamines are first-line treatment
-
Corticosteroids may be used short-term
-
Avoiding triggers is essential
If you or your child develop sudden itchy welts, don’t ignore it—monitor symptoms and seek medical advice if they persist or worsen.
