Introduction:

Urticaria, also commonly known as hives, is a skin condition that causes itchy, raised welts to form on the skin. These welts, or wheals, can vary in size and shape, and they can appear anywhere on the body.
Hives are a very common condition, affecting up to 20% of people at some point in their lives. They can be caused by a wide variety of triggers, including allergies, infections, medications, and stress.
In most cases, hives are not serious and will go away on their own within a few hours or days. However, in some cases, hives can be a sign of a more serious condition, such as anaphylaxis, which is a severe allergic reaction.

What causes urticaria?

Hives can be caused by a wide variety of triggers. The most common triggers include:

• Allergies: Allergies to foods, medications, insect stings, and other substances are a common cause of hives. Common food allergens include nuts, shellfish, eggs, and milk.

How is urticaria diagnosed?

Urticaria is usually diagnosed based on your medical history and a physical examination. Your doctor will ask you about your symptoms, when they started, and what triggers them. They will also examine your skin.

The treatment for urticaria depends on the cause and severity of your symptoms.
For most cases of acute urticaria, the hives will go away on their own within a few hours or days. However, if your hives are bothersome, your doctor may recommend the following treatments:

• Antihistamines: Antihistamines are medications that block the effects of histamine, a chemical that is released by the body when it has an allergic reaction. They are the most common treatment for hives.
• Corticosteroids: Corticosteroids are medications that reduce inflammation. They may be used for severe cases of hives or for hives that do not respond to antihistamines.
• Epinephrine: Epinephrine is a medication that is used to treat anaphylaxis, a severe allergic reaction. It may also be used for severe cases of hives.

There are two main types of urticaria:

• Acute urticaria: Acute urticaria is hives that last for less than 6 weeks. It is usually caused by a specific trigger, such as an allergy or infection.
