Patients with urticaria typically present with raised, red, and itchy welts on the skin. These welts can appear suddenly and may change shape, move around, disappear, and reappear over short periods. The itching can be intense, and scratching may worsen the condition. In some cases, urticaria may be accompanied by angioedema, which is swelling beneath the skin, often around the eyes and lips.

The workup for urticaria involves a thorough medical history and physical examination. Doctors may ask about recent infections, medications, foods, and stress levels to identify potential triggers. In chronic cases, further tests such as blood tests, allergy tests, or skin biopsies may be conducted to rule out underlying conditions. However, in many cases, the exact cause of urticaria remains unidentified.

Treatment for urticaria focuses on relieving symptoms and avoiding triggers. Antihistamines are the first line of treatment, as they help reduce itching and swelling. For more severe cases, doctors may prescribe corticosteroids or other medications to control symptoms. Identifying and avoiding known triggers, such as certain foods or medications, is also crucial in managing the condition.

The prognosis for urticaria is generally good, especially for acute cases, which often resolve on their own within a few days to weeks. Chronic urticaria can be more challenging to manage, but with appropriate treatment, most patients can achieve good control of their symptoms. In some cases, chronic urticaria may persist for months or years but often improves over time.

Urticaria can be triggered by a variety of factors, including allergic reactions to foods, medications, insect stings, or environmental factors. Non-allergic triggers such as stress, infections, or physical stimuli like pressure, temperature changes, or sunlight can also cause urticaria. In many cases, especially chronic urticaria, the exact cause remains unknown.

Urticaria is a common condition, affecting up to 20% of people at some point in their lives. It can occur at any age but is more prevalent in young adults. Women are slightly more likely to develop chronic urticaria than men. The condition can affect individuals of all races and ethnicities.

The pathophysiology of urticaria involves the release of histamine and other chemicals from mast cells in the skin. This release leads to the dilation of blood vessels, causing redness and swelling, and stimulates nerve endings, resulting in itching. The exact mechanisms triggering this release can vary and are not always fully understood.

Preventing urticaria involves identifying and avoiding known triggers. Keeping a diary of food intake, medications, and activities can help identify potential causes. Stress management techniques and maintaining a healthy lifestyle may also reduce the frequency and severity of episodes. For those with chronic urticaria, regular follow-up with a healthcare provider is important for ongoing management.

Urticaria, or hives, is a common skin condition characterized by itchy, red welts. It can be acute or chronic and is often triggered by allergic or non-allergic factors. While the exact cause is not always identifiable, treatment with antihistamines and avoidance of triggers can effectively manage symptoms. The prognosis is generally favorable, with many cases resolving over time.

If you experience sudden, itchy welts on your skin, you may have urticaria. These welts can appear anywhere on your body and may change in size and shape. While they can be uncomfortable, they are usually not serious. Over-the-counter antihistamines can help relieve symptoms, but if your condition persists or worsens, consult a healthcare provider for further evaluation and management. Keeping track of potential triggers can also help in managing the condition effectively.
