Urticaria

Hives are raised, often itchy, red welts on the surface of the skin. They are usually an allergic reaction to food or medicine.

 

Causes,

When you have an allergic reaction to a substance, your body releases histamine and other chemicals into your bloodstream. This causes itching, swelling, and other symptoms. Hives are a common reaction, especially in people with other allergies such as hay fever.

 

Incidence

When swelling or welts occur around the face, especially the lips and eyes, it is called angioedema. Swelling from angioedema can also occur around your hands, feet, and throat.

 

Risk factors

• Many substances can trigger hives, including:
• Animal dander (especially cats)
• Insect bites
• Medications
• Pollen
• Shellfish, fish, nuts, eggs, milk, and other foods
• Hives may also develop as a result of:
• Emotional stress
• Extreme cold or sun exposure
• Excessive perspiration
• Illness (including lupus, other autoimmune diseases, and leukemia
• Infections such as mononucleosis

 

Symptoms

• Itching
• Swelling of the surface of the skin into red- or skin-colored welts (called wheals) with clearly defined edges
• The welts may get bigger, spread, and join together to form larger areas of flat, raised skin.
• They can also change shape, disappear, and reappear within minutes or hours.
• The welts tend to start suddenly and go away quickly. When you press the center of a red welt, it turns white. This is called blanching.

 

Investigations

If you have a history of an allergy, then the diagnosis is even more obvious.

 

Occasionally, skin or blood tests are done to confirm that you had an allergic reaction and to test for the substance that caused the allergic response.

 

To reduce itching and swelling:

• Avoid hot baths or showers.
• Avoid irritating the area with tight-fitting clothing.
• Avoid exposure to substances that give you allergic reactions.
• Don't wear tight-fitting clothing and avoid hot baths or showers just after an episode of hives. These can both cause the hives to return.
