Allergy - What is an allergic reaction and what can you do about it?
An allergy is an unjustified and extremely strong physical response of the immune system to harmless substances from outside. One can be allergic to anything.

What is an allergic reaction?
Our immune substances to clean should not belong in our bodies. An allergy is an overzealous immune system against the efficacy of specific substances. Non-hazardous substances where our immune system reacts strongly to unjustly called allergens.
What causes an allergy?
When someone is allergic in nature, will his body through regular contact with an allergen, such as ...
• Inhalation
• Nutrition
• Physical contact
• Injection
• Insect stings
• Medical treatment
... Specific antibodies. This is called allergic sensitization. These antibodies - depending on the allergen - so attach to mast cells:
• Skin
• Mucous membranes
• Respiratory
• Nose
• Eyes
• Digestive
The formation and attachment of antibodies to mast cells can persist years unnoticed. Once mast cells, which have now have antibodies attached, again in contact with the relevant allergen, the allergen is recognized and the mast cells stimulated to issue large amounts of protective active substances (mediators). Too much makes you sick mediators. What a large scale protection action should be ends in a sickly, allergic condition.
