Urticaria, also known as hives, is a common skin condition characterized by raised, itchy, and red welts on the skin. Angioedema is a related condition that involves swelling in the deeper layers of the skin and tissues. The causes of urticaria and angioedema can include allergic reactions to food, medications, insect bites, or environmental triggers like heat, cold, or sunlight. Stress, infection, and autoimmune disorders can also contribute to the condition.
Treatment for urticaria and angioedema often involves identifying and avoiding triggers when possible. Antihistamines, corticosteroids, and other medications may be prescribed to relieve symptoms and reduce inflammation. For severe or chronic cases, other treatments like immunosuppressive drugs or biologics may be recommended.
If left untreated, urticaria and angioedema can lead to complications such as infections, scarring, and life-threatening swelling of the airways or other parts of the body. It's important to seek medical attention if symptoms persist or worsen.
