Causes and Symptoms of Allergy


The word allergy refers to a changed or unusual tissue reaction after it is exposed to an antigen or allergen. Allergy occurs when our body becomes too sensitive and gets susceptible to allergic reaction. There is no specific area in the body where allergy takes place. It can happen anywhere and is mostly caused by pollens, dust, cosmetics, animal hair, poisonous plants, serums, vaccines and drugs. At times, it can also result from over exposure to physical agents, such as heat, cold and sunlight.

On other occasions, it has been found that some food items can also be the reason for allergic reactions. Careless diets and faulty style of living are some other causes of allergy. Last, but nor the least, allergy might be the result of mental or physical stress and strain. Frequent headaches, eczema and swelling on the face and eyes are some of the symptoms of an allergy. If you are looking for some home remedies for curing the problem, the following tips will come handy.
