Allergist and Immunologist Questions Allergies

Do allergies change?

Can I be allergic to something for a while and then not be allergic to it anymore?

Yes, that can happen
Yes. We can both acquire or we can lose an allergy to given allergen over time.
Yes, that is possible. Allergies can change over time - sometimes new sensitizations develop or old ones resolve. It is important to follow up with your allergist on a regular basis and update your evaluation periodically. Especially if you note any changes in your reactions. 

Hope that helps. 
Allergies can change over time. With lack of exposure, there is a decrease in allergic antibodies. Some changes occur with aging. How they change over time depends on the allergy. Some drug or insect sting allergies decrease over time with lack of exposure.
