Chronic Urticaria

Chronic urticaria means hives, with or without deeper swelling called angioedema, that recur for six weeks or longer. The rash usually comes and goes, but the itching and uncertainty can be very disruptive. ^[1][2]

What is Chronic urticaria?

The condition is often driven by mast cell activation. In many people, no single external cause is found, which is why the term chronic spontaneous urticaria is commonly used. ^[1][3]

What are the symptoms and what causes it?

Typical features include itchy, raised wheals that change shape and location over hours, as well as swelling of the lips, eyelids or other tissues in some people. Triggers may include infections, pressure, heat, cold, NSAIDs or stress, but many cases are not caused by a classic allergy. ^[1][2][3]

How is it diagnosed?

Diagnosis is largely clinical and focuses on the pattern of lesions, duration and possible trigger clues. Extensive testing is not always needed unless the story suggests another disease or an inducible form of urticaria. ^[1][2]

What are the treatment options?

Non-sedating antihistamines are often the first-line treatment, sometimes at adjusted doses under medical guidance. Some people need additional therapies if symptoms remain uncontrolled. ^[1][2][4]

Possible complications and when to seek medical care

Chronic urticaria itself is often not dangerous, but swelling that affects the throat or trouble breathing requires urgent attention. The condition may also significantly affect sleep, concentration and quality of life. ^[1][2][3]

What may help in daily life?

Keeping track of possible triggers, photographs of the rash and the duration of individual lesions can help clinicians confirm the diagnosis and look for patterns. ^[2][3]

Common mistakes during follow-up

A common mistake is assuming every case is a food allergy. Another is using sedating treatments repeatedly without a clear long-term plan. ^[2][4]

How is chronic urticaria diagnosed?

Diagnosis usually starts with a medical history and examination, then moves to targeted tests depending on the symptom pattern and suspected cause. ^[1][2]
