How is this allergy managed?
Treatment options for non-IgE-mediated allergy are limited. The main stay really is complete removal of the offending allergen from the diet. This can be very hard to do because allergens are often hidden in processed foods.
However, improvements in food labelling are making this job easier, as is the expansion of ranges of 'free-from' foods in supermarkets.
Some non-IgE-mediated allergies are outgrown. For example, up to 80% of children outgrow cow's milk allergy by the age of five.
Other types of this allergy can be lifelong. There is also increasing evidence that some of these form of allergies can develop into IgE-mediated allergies after a period of elimination. Why that is we do not know, and it is an area that needs more research.
The good news is that the vast majority of individuals thrive once the offending allergen is removed from their diet, making the dietary modifications they have to make very worthwhile.
