Eczema used to be a relatively unusual skin condition. According to the American Academy of Dermatology, eczema is now becoming much more common. Up to 20 percent of children across the world will get eczema, or atopic dermatitis. Most people develop eczema before they are 5 years old, but older people can also have eczema. Since the condition is becoming more prevalent, eczema causes should be understood.
Causes of eczema. The exact mechanisms that set eczema in motion in certain people are largely unknown at this point. More research needs to be performed in order to find a direct cause, but studies have shown some interesting data worth taking into consideration.
Eczema risk factors. A genetic link exists for the development of eczema. The skin disorder tends to run in families. Eczema is also more common in families that have asthma and hay fever. Additionally, children are much more likely to have eczema if one or both parents have asthma or hay fever. Those that develop severe eczema also tend to develop either asthma or hay fever as well.
Food link to eczema. A few dietary sources may have a link to eczema. While foods cannot actually cause eczema directly, some food allergies may make eczema worse. Foods like milk, milk products, nuts and shellfish are often linked to allergic reactions. Never remove a food from a child’s diet, however, without first consulting with his or her doctor first.
Investigating eczema causes. Many unanswered questions remain about eczema causes. Research is ongoing, but it is thought that several factors in eczema development may interact with one another, bringing about the eczema reaction. The American Academy of Dermatology states that the immune system, the environment and genetics may work together to play a part in the disease’s origin.
