Spring allergies
In the spring many people complain from sneezing, runny nose, red eyes and tears or have their throat feel sore. These signs indicate the presence of an allergy, that is an abnormal inflammatory reaction of the body as an acute sensitivity to certain substances called allergens.
The are 3 types of seasonal allergies:
- Spring allergy caused by pollen of trees and shrubs – starts in mid March and ends in June
- Summer caused by graminea pollen allergy (grass, hay, rye, corn)
- The late summer allergy caused by herbaceous pollen
For allergy prone patients , the spring allergy often ends with an asthma acute crisis. Generally, the disease begins in childhood or early adulthood and may disappear along with aging.
Studies have shown that there are a hereditary genetic predisposition, such as a person who has a parent with an allergic disease in high risk of developing such a disease itself.
In a healthy person’s immune system is mandated to protect the body against foreign bodies such as bacteria, viruses or toxins.
On allergy prone people but this protection system is extra effective and perceived as too dangerous common substances such as pollen or mold flowers. In contact with an allergen, the body of an allergic person produces large amounts of antibodies (proteins that protect the body against disease) which is fixed on certain tissue and blood cells and release powerful chemical agents which, circulating through the body, trigger allergy symptoms.
