Solution Dear User, you have not mentioned the words limit in your question. so, a brief description of Allergies is provided below in my own words. Answer) Allergies are referred to several reactions or response as an outcome of hypersensitive reaction of our body’s immune system, when exposed to several allergic substances. these allergic substances are called as allergen. there are number of common allergens such as Dust mites, Pollens, Insect stings, Pet dander, Mold spores, Food, household chemicals and Medicines. these substances are not always allergic as the other people are not allergic to them, but some people are allergic to them. our immune system makes antibodies against the foreign particles entering our body. in case, when our immune system is weak (particularly in children) it is possible that encounter of such allergic substances during weak immunity may result in hypersensitive reaction. this first-time hypersensitive response is called as acute response when our immune system starts making antibodies against those substances. further multiple exposures to same allergens result in a higher response and the person becomes allergic to those substances. symptoms of allergies are sneezing, wheezing and coughing, a running nose or blocked nose, a red itchy rash, red itchy watery eyes. these symptoms can be observed within minutes of exposure to allergens. generally, these responses are mild but a prolonged hypersensitive reaction may result in anaphylaxis or anaphylactic shock which is a medical emergency. As per studies, one out of five American is affected with some sort of allergies. and the allergies are more commonly observed in the developed countries. there are different diagnostic tests to identify whether a person has an allergic response to possible allergens or not. these tests include patch testing, skin prick testing, blood testing etc. in these tests, a much smaller dose of allergen is provided to the person to observe the immune response. once a person is identified allergic to certain substance, it is consulted to avoid the exposure to those substances. while, in case of sudden exposure they are provided with the medications such as antihistamines, epinephrine and glucocorticoids etc. under certain limitations, immunotherapy is also provided as treatment against and asthma and allergies to insect bites.
