An 'allergy' can be described as sensitiveness of the body to a substance which does not normally affect other persons. There are innumerable substances in the environment which can cause mild to violent reactions in many people. These reactions range from true allergies due to intolerance of certain foods and substances, to those resulting from pollution.

Allergic reactions may occur within a few minutes of the patient coming in contact with the allergen, or they may be delayed for several hours or even several days. Almost any part of the body can be affected by allergies. The portion of the body which is affected is called a shock organ. Common sites are the nose and eyes, the skin, chest, intestines and ears.

Allergic reactions are caused by a wide range of substances and conditions. These include pollen, 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. Among the numerous allergens in the food department, the more common ones are oranges, milk, eggs, wheat, fish, chocolates, cabbage, potatoes, tomatoes and strawberries.


The symptoms of allergy are as varied as the substances causing the reaction.
These include recurring

  • headache,
  • migraine,
  • dizziness,
  • irritability,
  • nervousness,
  • depression,
  • neuralgia,
  • sneezing,
  • conjunctivitis,
  • diabetes,
  • eczema,
  • heart-burn,
  • hay fever,
  • indigestion,

  • asthma,
  • overweight,
  • high blood pressure,
  • chest pain,
  • heart attacks,

The same food can cause different symptoms in different people. Many allergies are multiple and may be caused by multiple allergens.
