CMPA

Also called cow's milk protein allergy, cows' milk protein allergy, cow's milk allergy, CMPI

CMPA stands for cow's milk protein allergy, an immune reaction to one or more of the proteins in cow's milk. It is mostly seen in babies and young children, and parents and health professionals often use the four letters on their own.

How it's said

  • I know what CMPA is but what's the LA bit?
  • Can anyone relate and tell me if they think he's got CMPA?
  • Just one other thing: a lot of people confuse CMPA with lactose intolerance.

Who says it

  • Parents
  • Parents on forums
  • Health visitors
  • Doctors

Not to be confused with

  • Lactose intolerance is trouble digesting lactose, the sugar in milk, and it is very rare in babies. CMPA is the immune system reacting to the proteins in milk, so the two are different things.

Where it came from

CMPA is the short form of cow's milk protein allergy. It used to be called cow's milk protein intolerance, or CMPI.

The Canadian Paediatric Society notes that the words around reactions to cow's milk are used inconsistently, which confuses doctors and families alike. NHS hospital leaflets for parents use CMPA in their titles, as in Managing Cow's Milk Protein Allergy (CMPA).
