1 Allergy to cow's milk proteins
- mediated by immunoglobulin E (IgE): its reaction is very fast, almost immediately after drinking milk, and the main symptoms are skin reactions, respiratory symptoms, edema ... or even anaphylaxis and shock.
- not mediated by immunoglobulin E: symptoms are later, which makes diagnosis very difficult (stools with red blood, vomiting, diarrhea, little weight gain, constipation, gastroesophageal reflux, severe colic ...)
2 Lactose intolerance
3 Gluten intolerance and celiac disease
4 Therefore, milk proteins, lactose and gluten are different things.
- Lactose intolerance is a condition in which the immune system does not come into play. It occurs when lactose is poorly absorbed by the body. In general, the symptoms are not serious, although they are very unpleasant and painful.
- As in any other food allergy, an allergy to cow's milk proteins involves the immune system, so if the child has a high degree of allergy, her life could be in danger if she comes into contact with this protein.
- In gluten intolerance there is an enzymatic deficit that does not allow gluten to be digested correctly. In this case, the immune system is not involved, as is the case with celiac disease. Therefore, we should not confuse both pathologies either.
