How allergy is different from asthma?
Hello, My Pulmonology Dr. said this was not Asthma, but can be swelling, tightness, or secretions in bronchitis. Referring me back to an allergist. Can anyone tell me how these two are different from one another? How is Allergy different from Asthma?
@aaana Hello, Allergies are basically an overreaction to substances called allergens (could be food, pollen, animal dander, etc.). The reaction in the body is a release of histamine when the body tries to rid itself of what it perceives as an offender. Usually, this is a temporary condition as long as the allergen is present and the host is exposed. Asthma is an actual blockage of the airways, which results in breathing difficulties. It can be brought on by allergies or by exercise, weather extremes, air pollution, etc. It is considered a chronic health condition, though it can be controlled with medication, therapy, biofeedback, etc.
