Differential diagnosis of food-induced symptoms.
The symptoms of patients presenting with non-allergic food-related reactions may partly mimic allergic responses. Therefore, correct delineation of food allergies is often difficult and various differential diagnoses have to be considered. We describe three cases of differential diagnoses to food-induced symptoms: A 14-month-old with lactose intolerance, an 8-month-old with severe diet-induced malnutrition and subsequent development of kwashiorkor and a 12-yr-old with chronic urticaria due to colouring agents. These cases represent common symptom constellations involving food-induced reactions. A proper and correct diagnosis of food-related symptoms is particularly important for children - not only in order to find the appropriate diet but also to avoid unnecessary exclusion diets, which may lead to severe impairments in growth and development.
