Food allergy: Can it develop later in life?
Is it possible to develop a food allergy as an adult? On two separate occasions in the last few months, I've developed bad stomach pains and itchy hives after eating shellfish. This has never happened before.

Answer
A food allergy can develop at any time in a person's life. So it's possible to develop a food allergy as an adult. But it's not clear why or how this happens.
Symptoms such as you describe may indicate a food allergy and should not be ignored. Subsequent reactions may be more severe and even life-threatening. Until you consult an allergy specialist, it would be wise to avoid eating any type of shellfish.
