Q: Can you develop an allergy later in life?
Yes. You can develop a new allergy
as an adult.
After you move to a new area, you may experience new allergy symptoms. You may be developing new allergies to the specific regional allergens you haven’t been exposed to in the past.
Similarly, you might also find that you are allergic to a food
you have never tried, such as shrimp or shellfish.
