Unraveling Urticaria: What Causes Those Itchy Hives?
Published: Aug 27, 2024
Urticaria, commonly known as hives, affects millions with its itchy, red welts. Discover the causes and what might trigger this skin condition.
Urticaria Uncovered
Urticaria presents as red, itchy welts that vary in size and shape. These welts can appear anywhere on the body and usually disappear within 24 hours. They are often accompanied by angioedema, which is deeper swelling in the skin, particularly on the face and extremities.
Common Culprits
The potential triggers for urticaria include infections, medications, foods, and insect stings. Viral infections are a frequent cause in children, while medications like NSAIDs can trigger hives in adults. Identifying a specific cause is often challenging, as many cases remain unexplained.
When It's More Than Just Hives
In some cases, urticaria can signal an underlying systemic disorder. Conditions like urticarial vasculitis or autoimmune diseases may present with persistent hives. It's crucial to consider these possibilities for a comprehensive diagnosis.
