What is a delayed or non-IgE-mediated food allergy?

Who commonly gets delayed food allergies and which foods cause it?


Who commonly gets delayed on non-IgE-mediated food allergy?

Delayed food allergy typically develops in children, but can develop in adults too. A lot of affected children present with poor growth, stomach pain, poor sleep and diarrhoea.

If this sounds like your child, please do get them checked out by your doctor. Food diaries can be so useful in identifying the offending cause.

Which foods are the typical offenders?

The biggest food by far is cow's milk (and a lot of other mammalian milks, for example goat), along with soy (often used as a milk substitute), wheat and egg.

What may your doctor suggest as a treatment?

If a non-IgE-mediated food allergy is suspected, your doctor may suggest a trial elimination of the suspected allergen (normally for a period of between two to six weeks). It is then usually suggested that the suspected allergen is reintroduced to see the reaction and confirm there is a definite allergy. This should be done in combination with professional advice.

If multiple or complicated allergies are suspected, your GP may refer you or your child to a specialist to form a care plan and order any tests that may be needed.
