What is allergic rhinitis?
Pollen Allergy is also known as seasonal allergic rhinitis. According to the Asthma and Allergy Foundation of America, pollen allergy is most commonly caused by grass whereas Ragweed is the main cause of pollen allergy caused by weeds Species of trees like oak, cedar, birch are also common sources of pollen allergy. Some people show the symptoms of pollen allergy throughout the year whereas others have them during a certain time of the year, depending on the type of pollen causing the allergy. When a human body is exposed to a foreign harmful invader, our immune system defends the body against these invaders to ward off illness. Pollen is a harmless invader however in people with pollen allergy when they breathe pollen the pollen releases water-soluble proteins on the respiratory lining. Their immune system recognizes these harmless proteins as harmful and dangerous invaders; thus it begins to produce chemicals to fight back the proteins produced. The body reacts to the threat by producing and releasing IgE antibodies. These IgE antibodies attach to most cells of the body to produce a chemical known as histamine.
Allergic Rhinitis Types and Symptoms
When histamine chemical is produced, a person shows symptoms like an itchy throat, red and watery eyes, running nose, sneezing and coughing. Hence, Histamine is the main cause of pollen allergy. Other common symptoms of pollen allergy are:
