translated from Spanish: What are allergies and why increase in September?

as we know, the largest number of allergic episodes in the Chilean population are given in September, because of the onset of pollinating trees, and in particular larly, of the well-known oriental plane. In this regard, Dr. Macarena
Sobarzo, Immunology clinic city of the sea, believes that early pollination of which there is talk these days has no necessary relationship with the drought our country suffers, but that there is a clear implication of the “in this global warming phenomenon”.
Along the same lines, it adds that higher temperatures and fecto greenhouse gases extend the pollination season and intensify at the molecular level of pollen allergenicity. Associated with this, there is a key genetic factor, will determine where the expression of genes associated with atopy, with an increased susceptibility to allergic diseases.
Symptoms and prevention the Krueger Sobarzo said that both persons nominated as perennial seasonal allergies should consult a specialist for handling with antihistamines and/or corticosteroids inhaled, as well, established a treatment to long term as immunotherapy provides it.
The pollen of all types, grasses, weeds and trees, top the list of most common allergens in the national population. So the presence of rhinitis and allergic conjunctivitis by these dates is common and occurs in individuals in a 30 and 20 percent respectively.
Allergic rhinitis symptoms are nasal and pharyngeal itching and watery rhinorrhea, sneezing, congestion nasal and loss of smell that can be associated to bronchial symptoms (dry cough and tight chest feeling) or conjunctival (red eye, eye itching and) tearing).
To prevent symptoms it is recommended to consult a specialist with a month prior to the onset of symptoms to start anti-allergy medications.
