Allergic asthma is the most common form of asthma*. Many of the symptoms of allergic and non-allergic asthma are the same. However, allergic asthma is triggered by inhaling allergens. An allergen is a typically harmless substance such as: dust mites, pet dander, pollen or mold. If you are allergic to a substance, this allergen triggers a response starting in the immune system. Through a complex reaction, these allergens then cause the passages in the airways of the lungs to become inflamed and swollen. This results in coughing, wheezing and other asthma symptoms.
Allergic Conjunctivitis (ocular allergy*) is the most common allergy affecting the eyes. Many people with allergies experience allergic conjunctivitis when their eyes come in contact with an allergen. The allergen triggers the release of histamine. This typically results in itching, redness, burning or tearing of the conjunctivae (the thin membranes lining the eyelids and the exposed surface of the eyes). Allergic conjunctivitis can be seasonal or perennial. The seasonal version is much more common. It is related to exposure to airborne allergens such as grass, tree and weed pollens or molds. The perennial form persists throughout the year and is usually triggered by dust mites, animal dander or molds. Irritants such as cigarette smoke, strong odors or fumes are not necessarily allergens, but they can make symptoms worse.
Sometimes called Immunologist, are specialists in the diagnosis and treatment of allergies, asthma and immune deficiency disorders. Allergists in the United States have completed medical school, at least three years of residency in pediatrics or internal medicine, then at least two years of specialized training in allergy and immunology. To be Board- Certified, they must pass an examination given by the American Board of Allergy* and Immunology. To maintain their board-certification, allergists must regularly attend continuing medical education programs in allergy and immunology. After completing medical school and graduating with a medical degree, physicians undergo three years of training in internal medicine or pediatrics and pass the exam of either the American Board of Internal Medicine (ABIM) or the American Board of Pediatrics (ABP). Make certain you are treated by an expert.
