What is Urticaria

Urticaria, also known as hives, is a common skin condition characterized by raised, itchy red or white welts on the skin. It occurs when the body releases a chemical called histamine in response to an allergic reaction or other triggers.

These raised welts can vary in size and shape and can appear anywhere on the body. They typically resolve within a few minutes to a few hours, but new welts may continue to appear in different areas. In some cases, urticaria can last for several weeks or even months, and this is referred to as chronic urticaria.

Urticaria can be triggered by a variety of factors, including:

1. Allergens: Common allergens include certain foods (such as nuts, shellfish, and eggs), medications (such as antibiotics or aspirin), insect bites or stings, and pollen.
2. Infections: Viral or bacterial infections, such as the common cold or a urinary tract infection, can sometimes lead to the development of urticaria.
3. Physical stimulation: Physical factors, such as pressure on the skin (from tight clothing or scratching), exposure to sunlight (solar urticaria), or exposure to heat or cold, can trigger urticaria.
4. Stress: Emotional stress or anxiety can sometimes trigger or worsen urticaria symptoms.
5. Autoimmune disorders: In some cases, urticaria can be a symptom of an underlying autoimmune disorder, such as lupus or thyroid disease.

The exact cause of urticaria is often difficult to determine, as it can vary from person to person. If you are experiencing recurrent or severe symptoms of urticaria, it is recommended to consult a healthcare professional for further evaluation and proper diagnosis.

Fortunately, there are several treatment options available to help manage and relieve the symptoms of urticaria. These may include over-the-counter antihistamines, corticosteroids, or other medications prescribed by a healthcare professional. Avoiding known triggers and adopting a healthy lifestyle can also be beneficial in managing this condition.
