Detailed explanation-1: -Overview. Allergies occur when your immune system reacts to a foreign substance-such as pollen, bee venom or pet dander-or a food that doesn’t cause a reaction in most people. Your immune system produces substances known as antibodies.
Detailed explanation-2: -Allergic reactions start in your immune system. If you are allergic to a substance such as dust, mold, or pollen and you come into contact with it, your immune system may overreact. It may make antibodies that attack the substance.
Detailed explanation-3: -An allergic reaction is a set of symptoms that the body develops in response to a foreign substance. An allergic reaction occurs when the body becomes hypersensitive to a substance, such as a drug, dust, or pollen. The reaction can be localized, in an isolated place in the body, or wide spread.
Detailed explanation-4: -When a harmless substance such as dust, mold, or pollen is encountered by a person who is allergic to that substance, the immune system may over react by producing antibodies that “attack” the allergen. The can cause wheezing, itching, runny nose, watery or itchy eyes, and other symptoms.
