What is the Atopic March?
The Atopic March is the term given to the progression of allergic or atopic conditions from infancy into childhood.
The ‘march’ usually starts with atopic dermatitis/eczema (AD in babies and sometimes progresses to food allergy, asthma, and allergic rhinitis (hay fever),
Just because there is an atopic march, it doesn’t mean that every infant or child who has AD will go on to develop any of the atopic conditions listed ! Only 60% of children with severe AD go on to experience other conditions within the Atopic March and for those with mild AD, the figure is only 20%.
The reasons behind the Atopic March as like those thought to be behind AD generally. A fragile skin barrier that lets possible food or environmental allergens in, triggering the activation of an immune response. Once the initial reaction has been experienced, the body identifies the food or environmental particle as an ‘enemy’ and reactions will manifest either as continuing AD or via other reactions such as hay fever, food allergy or even asthma.
