This is also a more common food allergy in children than in adults and although the milk that usually causes the allergy is cow’s milk, it can also be caused by the milk of other mammals, such as goats, sheep etc. Symptoms vary from person to person and can be mild or severe.
As mentioned at the beginning, allergy to milk is different from intolerance to milk or milk protein. Milk allergy is more common in children than in adults. In the latter case, the immune system does not intervene and, therefore, its treatment is different. Milk allergy can cause anaphylaxis and therefore can be fatal. Symptoms include rash, itching around the mouth, swelling in the mouth, difficulty breathing and vomiting, among others.
