What role does the immune system play in allergy?
In the case of an allergy, the immune system reacts not only to harmful intruders, such as bacteria and viruses, but also to substances that are in fact harmless. The immune system overreacts to the substance entering our body. The 'immunological' reaction that takes place leads to the production of IgE-antibodies in the blood, causing hypersensitivity. This process is also known as 'allergic sensitisation'. This sensitisation exacerbates your allergic symptoms every time you come into contact with the allergen that initially triggered the reaction.
