Avoidance of allergens
The best method for treating allergic diseases is to avoid exposure to the substances that trigger the symptoms, such as pollens or mites. However, this is hardly a practical solution. It is of course an advantage for patients to know what substances they are allergic to, particularly in the case of food allergies to avoid those allergens. And treatment recommended by doctors (diets, special building projects, holidays) must be reasonable and practicable to be followed by patients.
