Allergy Information

A reaction, which occurs in the immune system of the body, because of certain environmental substances is referred to as allergy. Known as atopy as well, allergy is characterized by extreme activation of certain white blood cells called mast cells and basophils. In general, our immune system fights germs and gives out signs in the context as well. However, in case of allergies, it raises false alarms. The foreign substance that enters the body, in case of allergies, is generally harmless and remains as such to non-allergic persons. Some of the most prevalent allergic reactions include eczema, hives, hay fever, asthma, food allergies, etc. Allergies range from being mild to moderate to severe. At times, they can be life threatening as well and prove fatal. Know more about the various causes and symptoms of allergy.
