If you feel itchy eyes, sneezing more than usual and have welts on the body … Most likely you are suffering from the dreaded allergy, an enemy who attacks us with more force when the spring begins.
What are allergies, what causes them?
An allergy is an overreaction of the body to a substance perceived as a harmful agent. The human body contains a number of components, cells and proteins that are responsible to defend when attacked by foreign agents. These components form the immune system.
Sometimes agents are considered harmful to the body, are not dangerous but that is as perceived by the defense system. When these agents come into contact with the body produces an exaggerated response that causes the symptoms of allergies. Substances that can cause this type of allergy are many but the most common are pollen, certain foods, medicines, etc.
Anyone can have allergic reactions?
There is a predisposition to allergies. For example in 1966 was found to be responsible for the immune system’s reaction to the pollen, was immunoglobulin E. Until then, only knew of other types of immunoglobulins, G, M, A and D.
It was through this discovery that identified what was happening to these patients when they came into contact with pollen.
They were detected in high concentrations of IgE antibodies (immunoglobulin E) directed against pollen grains.
E immunoglobulins bind to the pollen and release substances, histamine is one of them, producing reactions in the body leading to symptoms that characterize allergies.
