Allergy-Symptoms, Causes and Complication

Allergy is a common disease. The symptoms are experienced by many people. It is a word used to describe an adverse (bad) reaction that the body has to a particular substance in the environment. Allergies, if left untreated leads to many complications.
Most substances that cause allergies are not harmful and have no effect on people who are not allergic. It develops when the body’s immune system reacts to an allergen as though it is a threat, like an infection. It produces antibodies to fight off the allergen. Common allergic disorders include asthma, eczema and hay fever.
