What is an allergy?

An allergy is an excessive reaction of the immune system to small particles - the allergens - that hit the skin and mucous membranes. If such an allergen lands on the mucous membranes of the nose, eyes or bronchial tubes, the immune system, as the body's defence system, forms so-called antibodies that are directed precisely against a certain antigen. The antigens (allergens) can be very variable, e.g:

  • Animal epithelia
  • Pollen, grasses
  • Insect venoms (bees, wasps)
  • House dust mites
  • Moulds
  • Food / salicylates (aspirin)
