International guidelines developed to help doctors diagnose cow’s milk allergy may lead to over-diagnosis, according to University of Bristol-led research published in the journal Clinical and Experimental Allergy today [8 December]. The study found that three-quarters of infants have two or more symptoms at some point in the first year of life which guidelines say may be caused by cow’s milk allergy, yet the condition only affects one in 100.
Cow’s milk allergy can present with either acute or delayed symptoms. Delayed symptoms are more varied and include gut and skin symptoms, such as posseting (bringing up milk) and vomiting, colic, loose stools or constipation, and flaring of eczema.
