Red irritated eyes, constant sneezing, runny nose are common symptoms of inhalant allergies. Typical inhalant allergens are pollens from grasses, trees and weeds, mold spores, pet dander, and dust mites.
What causes the allergic reaction?
When your body encounters an allergen for the first time, your immune system over-reacts and produces IgE antibodies.
The more times you are exposed to an allergen, a chain of reactions occurs in your immune system. The most important of these is the release of a chemical in your body called histamine. Histamine can be present in the nose, sinuses, ears, and throat. It is the production of histamine that produces your allergic symptoms.
Over 40 million Americans are living with inhalant allergies. Unfortunately, allergens sufficient to cause a reaction can be found extensively in the environment. Prominent grasses, trees, weeds, including ragweed, plus indoor and outdoor molds have the potential to cause an allergic response. Your doctor may ask you at which time of the year are you most troubled by allergies. For example, pollen travels the most easily in hot, dry, windy weather, so these conditions can worsen your allergy symptoms. Dust mites, pets and cockroaches are some of the most common indoor allergy triggers. In order to get relief from allergy, patient history, early diagnosis and treatment is very important.
