What is allergy?
First reaction is altered, ie a wrong and harmful response of the body’s defense mechanism against substances that usually are harmless.
Normally, the human body defends itself against harmful substances such as viruses or bacteria, but sometimes the defenses aggressively attack usually innocuous substances such as dust, some fungi, or pollen.
The immune system generates large amounts of antibodies called immunoglobulin E (IgE), a complex chemical weapon to attack and destroy the supposed enemy. Each IgE antibody specifically targets a particular allergen – the substance that causes allergy. In this process of combating the disease, are released or produced inflammatory chemicals, and will be responsible for all these uncomfortable symptoms (and, in extreme cases, life threatening).
