Children with eczema: the link to food allergies is not clear cut
Children’s allergy specialist, Dr Robert Boyle, unpicks the evidence behind the value of allergy tests for children with eczema.
Around one in five children have eczema – and even mild cases can have a big impact on both the child and their family. For many, symptoms will come and go before they start primary school, but for others it can indicate the beginning of a genetic tendency to develop allergic conditions such as hay fever or asthma (or both).
