Can Asthma Cause Atopy?

When you have atopy, your immune system is more sensitive to common allergic triggers that you breathe in or eat. So you have a stronger-than-normal reaction to these allergens, such as dust, pollen, peanuts, or shellfish. If you have allergies or asthma, there's a chance atopy is behind it.

Is atopy associated with asthma?

Share this page: Atopy refers to the genetic tendency to develop allergic diseases such as allergic rhinitis, asthma and atopic dermatitis (eczema). Atopy is typically associated with heightened immune responses to common allergens, especially inhaled allergens and food allergens.

Does atopy always precede asthma?

Atopic March (Triad)

The “atopic march” describes the tendency for AD to precede the development of other atopic diseases such as food allergies, asthma, and allergic rhinitis in a temporal sequence. A 2008 study showed that the march does not necessarily always happen in order, as some patients with asthma develop AD.
