Allergy - The Voice of the People

The voice of the people. We need to do more. The adaptive immune response provides specific protection against infection with bacteria, viruses, parasites, and fungi. The immune system is devised by nature primarily to protect the human body against pathogens. Sometimes the system becomes over enthusiastic and brings discomfort This phenomenon is similar to the over-enthusiastic servant who tried to kill the fly sitting on the King’s nose with a strong sharp knife. Immune response is always directed towards the protection of the host. But in Hypersensitivity, the immune response becomes injurious to the host. Hence the immune response becomes a destructive process in hypersensitivity.

In a protective immune response, the antigen or bacterium or virus is killed or neutralized.But in Hypersensitivity, the cells of the host are killed or the host itself isdamaged or killed.Hypersensitivity is the changed reactivity of the immune system.It is a beneficial protective system gone out of order.In clinical terms hypersensitivity is called Allergy.Some immune responses, however, give rise to an excessive or inappropriate reaction-this is usually referred to as hypersensitivity term “hypersensitivity”, or “allergy”, (1).In a given individual, such reactions typically occur after the second contact with a specific antigen(allergen). Your immune system process antibodies to halt the “invasion”. The resulting chemical release can cause skin reactions, breathing problems and digestive difficulties.
