Cows’ Milk Allergy (CMA)

Cows’ Milk Allergy

Cows’ milk allergy is the most common food allergy in babies and young children. But for many it can take numerous visits to medical professionals and months of treatment before the cause of their symptoms is finally identified. This is partly due to a low awareness of cows’ milk allergy amongst parents and healthcare professionals as well as treatment focusing on the individual symptoms, such as eczema and colic, rather than the underlying cause.

There are different types of cows’ milk allergy with differing symptoms – some children suffer immediately and others have a delayed response, showing symptoms hours or even days later. The chart below shows some common signs and symptoms that may indicate an immediate or delayed allergy to cows’ milk:
