Allergic disease may undergo dynamic changes over time, and the term "allergy march" is often used to describe this characteristic disease progression. Because allergies change over time, many people will outgrow allergies they’ve had and develop new ones. The allergy march, also called the allergic march or atopic march, is a specific way that allergy symptoms often progress in children.8
Allergic eczema is often the first step of the allergy march.9 Children with early onset eczema are three times more likely to develop allergen sensitization by the age of two.10 As the march continues, children are at increased risk to develop allergic rhinitis or asthma later in life.10-13
