How are allergies formed?
Allergens over stimulate your immune system and sometimes, for some UNKNOWN reason, your immune system not only identifies and destroys the chemical "intruder" but as a side-effect it produces toxic chemicals itself. A common chemical is histamine (hense Anti-histamine meds ex. Claritin and flonase) that is responsible for the symptoms of an allergy.
Up to 20% of the US population are affected by a food allergy resulting in diarrhea, nausea and upset stomach. Contact dermatitis (I think thats how you spell it?) is an allergy to a chemical coming in contact with your skin, such as a certain brand of soap,detergent or shower gel. Your symptoms will probably appear in the form of an itchy rash. The long and short of it... sometimes your born with an allergy and grow out of it and sometimes they just show up...In an allergic reaction the immune system mistakenly interprets a harmless substance as a harmful one. The immune system responds by producing antibodies. These antibodies are designed to help neutralize specific parasitic invaders and protect the person from future exposures. Upon first exposure to an allergen, no allergic symptoms develop. But when the person is exposed to the same substance at a later time, the antibodies against the allergen activate an allergic reaction. Allergy symptoms may include itching, sneezing, a stuffy nose, watery eyes, swelling of the airways in the lungs and wheezing (asthma), and even allergic shock and death in RARE situations.
I don't know that answer but I know I hate them. I also hate food allergies like shrimp. I think I have a new one Peanut Butter. The trick is that I was eating them fine before.
