Chronic idiopathic urticaria is a term used to describe hives that occur at least twice a week and last for more than 6 weeks. It is a condition characterized by the development of itchy, raised patches on the skin. These hives can be very uncomfortable and may appear swollen. Chronic idiopathic urticaria is also known as spontaneous urticaria, with an unknown identifiable cause.
Common symptoms of chronic idiopathic urticaria include the presence of a rash consisting of smooth, raised welts of varying shapes and sizes. These hives can cause itching, burning, and stinging sensations. They may feel warm to the touch and often run together to form large, raised patches on the skin. In some cases, hives may appear in specific areas or cover a significant portion of the body.
The exact cause of chronic idiopathic urticaria is not fully understood by medical professionals. It is believed to be linked to a dysfunction in the autoimmune system, leading to the release of histamine in the body. Histamine plays a crucial role in modulating allergic reactions, and its release without a real threat can cause hives. Various triggers, including allergic reactions, exposure to extreme temperatures, stress, pressure on the skin, and certain medications, can lead to the development of chronic idiopathic urticaria.
Diagnosing chronic idiopathic urticaria often involves a dermatologist examining the skin and taking a person’s medical history. They may conduct a skin biopsy to confirm the diagnosis and determine the underlying cause of the condition. Individuals with hives lasting for 6 weeks or longer are typically diagnosed with chronic idiopathic urticaria.
While hives usually resolve on their own, treatment for chronic idiopathic urticaria aims to control itching, prevent new hives from developing, and avoid triggers. Dermatologists may prescribe soothing lotions, antihistamines, corticosteroids, or omalizumab to alleviate symptoms. Light therapy can also be used as a noninvasive treatment option for chronic idiopathic urticaria.
For some individuals, specific foods may trigger hives. Peanuts, eggs, shellfish, and certain additives present in foods can lead to allergic reactions. Keeping track of food intake and undergoing a skin prick test can help determine which foods may be causing hives. Once identified, avoiding these triggers can help manage chronic idiopathic urticaria effectively.
Chronic idiopathic urticaria is a challenging condition that causes prolonged hives on the skin. While the exact cause remains unclear, various triggers can lead to the development of hives. Treatment options, including medications and light therapy, can help alleviate symptoms and manage the condition. By identifying and avoiding triggers, individuals can effectively manage chronic idiopathic urticaria and improve their quality of life.
