HIVES:

An allergic reaction to a drug or food usually causes hives. People who have other allergies are more likely to get hives than non-allergic people; but hives can be caused by infections and stress as well.

What are hives (or urticaria)?

Hives are an inflammation of the skin triggered when the immune system releases histamine. Two kinds of hives exist: acute and chronic. Acute cases happen after eating a particular food or coming in contact with a particular trigger. Chronic hives can last for months or years.

 

Hives can result from non-allergic causes such as heat or exercise. Hives can also be an allergic reaction to medications, foods or insect bites. Although often uncomfortable and sometimes painful, hives are not contagious.

 

What are the symptoms of hives?

Hives are identified by a swelling of the skin or raised red or white bumps or welts. Hives can appear anywhere on the body and can vary in size of the affected area. Hives can also move from one place to another. Because of the released histamine, the area will itch.

 

How are hives diagnosed?

The allergists/immunologists at Allergy & Asthma Physicians of Rochester Hills will conduct allergy testing to determine what may be triggering your reaction. If you notice a reaction when eating a particular food or coming in contact with a particular item, plant or animal, please be sure to let us know.

 

How are hives treated?

If we can determine the cause of your hives, simple avoidance will help minimize or eliminate your symptoms. Most hives reactions can be treated with oral antihistamines. Severe flare-ups may require taking corticosteroids to reduce inflammation.
