Nearly one in 3 is affected by a problem today and allergic figures continue to rise steadily.
Many allergists believe that even in less than 10 years, a person is allergic 2
The percentage of allergies has doubled in 15 years in industrialized countries which particularly alert all doctors, including allergists, whereas this figure was just 5% in the early 70s.
Allergic diseases are ranked fourth by the WHO.
The most pessimistic forecasts give third place to allergies in the next decade.

* 40% of French have every opportunity to develop allergic manifestations.
* Allergies have assumed different forms over the last twenty years:
o The allergens involved are becoming more
o The allergic manifestations are more different in their lives.
o The age of onset of allergies now stretches from birth to over 80 years.
o Along with the increasing number of allergy sufferers, the features of manifestations of allergy has changed over recent years become increasingly severe and persisting longer. The person who made severe events and have had need to consult urgently have been multiplied by 40 for 10 years.
* 400 million people worldwide suffer from allergic rhinitis.
* 300 million people worldwide have asthma.

Yet over 50% of allergies are not diagnosed as such do not receive appropriate treatment and live events with embarrassing and sometimes debilitating worsening over the years.
The environment changes, our habitations, a comfortable life increasingly cozy, the increased use of cars, food very different from 30 years ago, advances in medicine and the frequent use of antibiotics are largely responsible for the explosion of allergies.
Our homes
Since the oil crisis of 1974, the lifestyle in industrialized countries have changed: A better insulation, smaller apartments, better insulated, more heated and the introduction of air resulted in a containment and a higher rate of ‘moisture thus promoting the development of mites, public enemy number one with allergies.
The loss of simple habits, such as suspending the sheets on the windowsills, a situation that now rarely seen, even in villages, has only increased the number of allergies.
Animals
On the other hand, the proliferation of pets is constantly increasing. More than ten million dogs, many cats and birds, hamsters, guinea pigs, rabbits and other exotic animals have invaded our homes. The rats also won a lot of success with girls since the success of the animated film Ratatouille.
More than one in two households owns a pet, also contributing to this increase in the number of allergy sufferers.
The landscape pollen
The landscape of our country has also changed over the last thirty years leading to an explosion of pollen into the environment more and more important every year, so that the term “pollution green is now used to pollens.
We begin to find pollen in the south of France to the north.
Our eating habits
The profound changes in our eating habits also contribute to this scourge of allergy. The French began to appreciate more and more menus Maghreb, Asian, Caribbean and exotic fruits like kiwi, mango, papaya.
Consumption patterns of food, with the development of frozen and canned, has also changed dramatically with the introduction of hundreds of new proteins to improve taste, change the color, consistency ….
Excessive hygiene

The arrival of many new allergens has destabilized our immune system has not managed to adapt to profound changes in our environment.
This one used to fight against microbes and viruses. The use of vaccines and the use of antibiotics has decreased the number of infections. Destabilized, our immune system has evolved and began to struggle against seemingly harmless items such as pollen or dust mites.
This explanation, called Officer theory is demonstrated by numerous studies showing that children living on farms in contact with germs developing in contact with the animals developed fewer allergies than those living in cities. Similarly, children living in families, frequent contact with microbes develop less allergic.
