Do you know about Urticaria (Hives)

Posted on: November 12, 2008

Hives (urticaria), also known as welts, is a common skin condition with itchy, pink to red bumps that appear and disappear anywhere on the body. An individual lesion of hives typically lasts a few hours before fading away, and new hives can appear as older areas disappear.images5

Physicians arbitrarily divide hives into acute (new or periodic episodes lasting fewer than 6 weeks) and chronic (periodic episodes lasting more than 6 weeks). Though many people have a single episode of acute hives that goes away within a few days to weeks, some individuals may have chronic hives, periodic (recurrent) attacks of hives that come over periods of years.

Hives can be triggered by many things, including:

* Medications, especially aspirin, ibuprofen, naproxen, narcotic painkillers, or antibiotics
* Infections with viruses, bacteria, or fungi
* Environmental allergies such as insect bites, pollen, mold, or animal dander
* Physical exposures such as heat, cold, water, sunlight, or pressure
* A medical condition such as gland diseases, blood diseases, or cancer
* Food allergies, such as strawberries, eggs, nuts, or shellfish
* Stress

In approximately 50% of idiopathic urticaria outbreaks, hives are most likely caused by a reaction from the person’s own immune system (autoimmune reaction).
