Pollen allergy affects about six and a half million Spaniards, of whom 14% suffer rhinoconjunctivitis, and about 40% asthma, according to data from the SEAIC. The incidence of allergies is increasing, and the patient's profile has also changed in recent years. According to the president of the Society, Dr. Tomás Chivato, contamination and the proliferation of plant species from other countries are behind the increase of this type of pathologies in Spain.
Wild grasses such as weeds, grass, and herbs that grow freely in the field, are the main responsible for pollen allergy in our country, followed by olive and parietaria. These plants make up 20% of the plant surface.
14% of allergic sufferers suffer rhinoconjunctivitis and 40% asthma. It appears more frequently in adults, which shows that environmental factors are decisive
The specialists warn that this spring will be especially annoying for those allergic to grasses, unless unexpected weather variations occur. And is that, according to the prediction of a method, which takes into account the rains of the months of autumn and winter, devised by Javier Subiza, current coordinator of the committee of aerobiology of the SEAIC, this spring can reach 5,100 grams per cubic meter of air, almost twice as much as in 2009.
The pattern of evolution of the allergy, that is to say, how the symptoms of this pathology vary since the child is born until the age of five, when asthma manifests itself, continues to recur in many allergic people; However, a phenomenon that was not there before was occurring, and that is that these discomforts are also appearing in adults, and even the elderly, who previously had not presented allergy symptoms. According to Dr. Chivato, a couple of decades ago it was very uncommon for allergy to manifest for the first time in the Third Age. This change in the incidence of allergy is proof that, in addition to the genetic predisposition of each individual, the development of the pathology is determined by environmental factors.
