nokkosihottumasta

Nokkosihottuma, also known as urticaria, is a common skin condition characterized by the sudden appearance of raised, itchy welts called hives. These hives can vary in size and shape and may appear anywhere on the body. They are often accompanied by intense itching, and in some cases, burning or stinging sensations.

The underlying cause of nokkosihottuma is typically a release of histamine and other chemicals in the skin, leading to fluid leakage from small blood vessels. This leakage causes the swelling and redness characteristic of hives. Common triggers include allergic reactions to foods, medications, insect bites or stings, and environmental allergens like pollen or pet dander. Non-allergic triggers can include infections, stress, physical stimuli such as heat, cold, or pressure, and certain autoimmune conditions.

Nokkosihottuma can be classified as acute or chronic. Acute urticaria typically lasts less than six weeks, often resolving on its own. Chronic urticaria persists for longer than six weeks, and in many cases, the exact cause remains unknown. Diagnosis often involves a thorough medical history and physical examination. Allergy testing may be performed if an allergic trigger is suspected.

Treatment for nokkosihottuma primarily focuses on relieving symptoms and identifying and avoiding triggers. Antihistamines are the mainstay of treatment, effectively reducing itching and swelling. In more severe or persistent cases, corticosteroids or other medications may be prescribed. For chronic forms where triggers are not identifiable, long-term management may be necessary. While generally not a serious condition, severe cases with swelling of the airways can be a medical emergency.
