Allergic Diseases on Its Peak: Fortis Doctor Informs School Students

Although almost any tissue in the body may be affected by allergy, yet it has a predilection for respiratory tissue and skin. The commonest manifestations are Asthma, Allergic Rhinitis, Allergic Conjunctivitis, Drug allergy, Food allergy, Insect allergy, Eczema, Urticaria, Angioedema and Anaphylaxis.

Speaking about the major sources of allergic symptoms Dr. Swati said, “Airborne dust and its particles, which include pollen grains, fungal spores, animal dander, mites and other allergens in indoor air, are major sources of allergic symptoms. They enter into the respiratory tract of human beings and trigger hypersensitivity reaction which is manifested in the form of allergic rhinitis, bronchial asthma, atopic dermatitis, eczema, gastrointestinal and autoimmune diseases.”

“Pollen grains are amongst the earliest known allergens and are found to be the major causes of bronchial asthma and allergic rhinitis. Seasonal allergic rhinitis usually caused by pollen grains of those plants which flower in a particular season for a short duration. Pollens can also irritate the eyes causing Allergic conjunctivitis”, she further added.

There are several reports from Europe and USA that climate change (global warming) increases the duration and concentration of pollens in the air because of early flowering and late finish during the season. Increased cabondioxide enhances the growth of plants and productivity of pollens. The sufferers of seasonal allergy know that some days will be worse than the others depending upon the prevailing weather conditions.

“People usually complain of catching cold soon in every season. That may be because he or she may be suffering from nasal allergy due to pollen grains which is perennial and may last for weeks or months. Whereas, cold usually lasts for 7-10 days”, stated Dr. Swati.

If one parent is atopic, then the chances of the child getting atopy are 50%. If both the parents are atopic then the chances of the child getting affected are 75%. Small houses, inadequate ventilation, dusty environment, usage of carpets and upholstery are recorded to know that dust mites may be the probable allergen. Wet environment and water seepage favors the growth of molds. Day care centers can be the source of recurrent viral and bacterial infections in children.

Speaking about the dire need for an evaluation of suspected allergy Dr. Swati said, “It must include a detailed history, thorough physical examination and appropriate diagnostic tests which include blood tests like complete blood counts, IgE levels, absolute eosinophilic count, allergy skin test, RAST and radiological investigations.”

“With the advent of new standardized tests and tools, the quest for allergy has found new horizons and success in finding out the allergen and curing the patient completely. But unlike other diseases, allergist needs to be thorough with the patient’s past and present history, family history as well as his diet, lifestyle, outdoor and indoor environments, drugs and so on”, she further added.
