Allergies and heredity

It is known that allergies run in families, with a approxiamtely 50% of the population suffering with allergic reactions..
  • These people, are known as hypersensitive or atopic and produce large amounts of antibodies against certain allergens.
  • Their sensitivity is encoded in their genetic makeup, which is passed on by their parents through their chromosomes.
  • Atopic people are likely to pass it on to each generation. So the cycle never ends!


A hypersensitive person does not necessarily develop an allergic disease.
The earlier preventive measures are implemented, the less likely there will be allergic reactions.
Yet, for a few years now, there has been a noticeable increase in the number of people allergic to pollens with no atopic (hypersensitive) background.

Risks for children

  • If a mother is allergic , the risks of her child developing allergies will be between 30% and 40%.
  • If the father is allergic, this risk will be of 30%.
  • If both parents are allergic, this risk will be between 70 and 80%.

It is useful to bare your family history in mind especially when a person is showing chronic symptoms such as allergic rhinitis, coughs, asthma, eczema....
A medical assessment by a doctor who specialises in allergy can identify the specific allergens and put in place an appropriate therapeutic treatment plan.
