The allergy march² is a series of allergic diseases that follow a fairly defined path as the allergic patient ages. Typically, eczema occurs between birth and three months of age; gastrointestinal symptoms related to food allergens are most prevalent during the second year; allergic rhinitis and other upper respiratory conditions due to inhalant allergens, as well as recurrent otitis media, generally manifest between the ages of three and seven; and asthma is usually diagnosed between the ages of seven and fifteen. Early diagnosis and appropriate treatment of allergies is vital in order to interrupt the progression of the disease and thus derail the allergy march.
