Atopy -

Atopy typically follows a predictable chronological progression:

Atopy is a genetic predisposition toward developing exaggerated IgE-mediated immune responses to common environmental allergens. Clinically, it manifests as a triad of conditions—, allergic rhinitis (hay fever) , and allergic asthma —often appearing sequentially in a pattern known as the "atopic march". 1.

While there is currently no cure, management focuses on controlling inflammation and restoring barrier function. Atopy - StatPearls - NCBI Bookshelf - NIH allergic rhinitis (hay fever)

: Upon re-exposure, allergens cross-link IgE on the surface of mast cells, causing degranulation and the release of inflammatory mediators like histamine and leukotrienes. 2. The Atopic March allergic rhinitis (hay fever)
