1. What is a milk allergy?


Allergies are the body's immune system's defensive response to a foreign object (in this case, proteins in milk). This means that when children drink milk, their immune system will mistake the proteins for harmful foreign antibodies and start working against them, causing milk allergy in babies. Similarly, the baby's body will find it difficult to absorb the proteins in formula milk, accompanied by allergic reactions, so the child may become depressed and lack nutrition. Depending on the signs of an allergy to formula milk, we determine the severity of the reaction. Often children who are allergic to the proteins in cow's milk will also react to the proteins in sheep's and goat's milk.

In addition, the appearance of allergic diseases also depends on the location, living environment and daily diet of the child. The manifestations of milk allergy in children are often a combination of many symptoms and these symptoms will increase if the child continues to be given the allergen milk.
