Allergy More Condition_symptoms Does Eating Something You Are Allergic To Make You More Sensitive To The Allergy?

Does eating something you are allergic to make you more sensitive to the allergy? - allergy more condition_symptoms

I am allergic to apples, my mouth itch. If I eat a lot of apples, make me allergic? Or less? Or remain unchanged?

What about dog / cat allergies, so I am exposed to a lot of cat hair, for example, to tolerate me cat shed? Or less?

Thanks
