The word 'allergy' means an altered or abnormal tissue reaction after exposure to an antigen (also called an 'allergen'). The allergic reaction occurs if the body tissues are sensitive to the allergen. The allergen may reach the tissues by direct contact with the skin or various mucous membranes of the organs or through the bloodstream after absorption. Almost any part of the body can be affected by allergies. Allergic reactions are caused by a wide range of substances and conditions. These include pollens, dust, cosmetics, and animal hair; poisonous plants, serums, vaccines, and drugs; physical agents such as heat, cold and sunlight, as well as a variety of foods. The foods that commonly cause allergic reactions are oranges, milk, eggs, wheat, fish and other sea foods, chocolates, tomatoes, and strawberries.
