[Cow's milk protein allergy].

Cow's milk protein allergy affects gastrointestinal morphology and function. The clinical symptoms depend on the localisation in the gut and on the type of the allergic reaction. In some patients cutaneous, respiratory and even urinary symptoms may also be present. As the condition is almost limited to the first year of life, transitory elimination of cow's milk from the diet is the treatment of choice. A number of patients with intractable diarrhoea suffers from undiagnosed cow's milk protein allergy.
