Hives
(Redirected from Urticaria papulosa)
Hives, also known as urticaria, is an itchy, inflamed skin rash that typically results from an allergic reaction. It manifests as raised, often red, bumps (wheals) on the skin that can appear anywhere on the body. Hives can be a distressing condition, but it is usually not life-threatening. However, in some cases, it can be a sign of a severe allergic reaction that requires immediate medical attention.
Overview[edit | edit source]
Hives are generally characterized by sudden outbreaks of swollen, pale red bumps, plaques, or welts on the skin. They can occur singularly or can connect to form larger areas known as plaques. They are usually itchy, but can also burn or sting. The lesions can appear on any part of the body and may move around, disappear, and reappear over short periods.
Causes and Triggers[edit | edit source]
Hives are often a response to the body's release of histamine as part of an allergic reaction. Common triggers include certain foods, medications, infections, insect bites or stings, exposure to sunlight or cold, stress, exercise, and contact with certain chemicals or plants. In some cases, the exact cause of hives can't be identified, a condition known as idiopathic urticaria.
Diagnosis[edit | edit source]
Diagnosis is typically based on the distinctive appearance of the rash and its tendency to come and go. In some cases, a doctor may recommend allergy tests to identify the cause of hives.
Treatment[edit | edit source]
The first line of treatment for hives is to identify and remove the trigger, if possible. Antihistamines are commonly used to relieve symptoms. In severe cases, corticosteroids or other drugs that suppress the immune system may be used.
Complications[edit | edit source]
In rare cases, hives can be part of a severe allergic reaction known as anaphylaxis. This is a medical emergency and requires immediate treatment.
