The main organs that suffer from food allergies are the gastrointestinal tract, skin and respiratory system. Therefore, the most common symptoms are:
- coryza;
- cough or frequent sneezing;
- redness, rash or itching of the skin;
- nausea, vomiting, or intestinal colic.
Having found out the relationship of signs with several food products, you can find out what an allergy is, by doing such an analysis as a provocative elimination test - the reproduction of an allergic reaction by taking an allergen. It will allow to exclude suspect products, which are actually absolutely safe for health. During this study, all antiallergic drugs must be withdrawn.
In addition to provocative elimination tests, to learn what a person is allergic to, such studies as skin tests will help. It can be scarification tests with simultaneous application of different allergens or prik-test. With their help, you can identify not only the causally significant allergen, but also the exact degree of sensitivity to the organism.
