Nickel allergy is a common cause of allergic contact dermatitis — an itchy rash that appears where your skin touches a usually harmless substance. Nickel allergy is often associated with earrings and other jewelry. But nickel can be found in many everyday items, such as coins, zippers, cellphones and eyeglass frames.N
Nickell is one of the most common causes of allergic contact dermatitis: a skin rash or irritation caused by touching an allergen. In fact, it is estimated that more than 18 percent of people in North America are allergic to nickel, including 11 million children in the U.S.
If you have a nickel allergy, the best way to avoid symptoms is to avoid objects containing nickel. However, this can be challenging, since nickel is present in many common household items.
Allergic contact dermatitis occurs when a red, itchy rash develops on skin that has touched an allergen. An allergy to nickel is among the most common causes of this reaction.
Rashes often occur on the earlobes or wrists, because many earrings and watches contain nickel. The reaction may occur immediately after contact, or it may develop after repeated exposure.
When a person with a nickel allergy comes into contact with the metal, their immune system mistakenly believes that it is causing harm. The immune system produces a hormone called histamine in response. This can cause a rash to develop, as well as other symptoms.
Here, we look into the everyday objects and foods that contain nickel and provide detailed information about the allergy, including symptoms, methods of diagnosis, and treatment options.
