Your body does this in order to fight off the allergens. Unfortunately with an allergy, the immune system is not always able to defeat the allergen's effect. The second time you are exposed to an allergen, it reacts with the specific IgE type antibodies in your system. This causes a chain of reactions in your body. The most important of these is the release of a chemical in your body called histamine.
Histamine can be present in the nose, sinuses, ears, and throat.
Unfortunately, allergens sufficient to cause a reaction can be found extensively in the environment. Ragweed plant, grass pollens, dust, wool, and even common household mold and mildew have the potential to cause an allergic response. In order to get relief from allergy, early diagnosis and treatments are very important. Conrad Concepts offers colorful buttons, stickers and other products to remind people that your child has an allergy.
