What is Urticaria?
Urticaria, also known as hives, is a skin condition characterized by itchy, raised, and red welts or bumps on the skin. These bumps may be small or large and can appear anywhere on the body, sometimes in clusters.
Urticaria occurs when the body releases histamine and other chemicals in response to an allergen or trigger, causing the skin to become inflamed, red, and intensely itchy.
Symptoms of Urticaria
The main symptom of urticaria is the sudden appearance of raised, red, and itchy bumps or welts on the skin, known as hives. They can disappear quickly or persist for hours or days, and may cluster or spread over a larger area.
- Intense itching or burning sensation
- Swelling around the affected area, sometimes warm to touch
- Pale or red skin around the hives depending on severity
- In rare cases, swelling of the throat or other areas causing difficulty breathing or wheezing
Severe or persistent symptoms require immediate medical attention.
Causes of Urticaria
Urticaria can be triggered by a variety of factors. Common causes include:
- Allergic reactions: reactions to foods, medications, insect bites or stings, or environmental allergens like pollen, dust, or animal dander
- Infections: viral or bacterial infections, such as strep throat, that trigger an immune response
Identifying the underlying cause is important for effective management and prevention of future episodes.
Importance of Specialist Care
Recurrent or chronic urticaria can significantly impact quality of life. Early evaluation by a specialist ensures proper diagnosis, identification of triggers, and tailored treatment to manage symptoms and prevent complications.
Role of a Specialist
A dermatologist or clinical immunologist assesses your condition, determines the underlying cause, and develops a personalized treatment plan which may include antihistamines, lifestyle modifications, or advanced therapies for chronic cases.
