Allergies


Allergies: An allergy is a hypersensitivity disorder of the immune system. Allergic reactions occur when a person’s immune system reacts to normal harmless substances in the environment.

A substance that causes a reaction is called an allergen. Mild allergies such as hay fever are very common with symptoms like itchiness, hives, runny nose, eczema or an asthma attack. In some people severe allergies to environmental allergens, food or medication may result in life-threatening reactions.

Some of the most common allergens include:
  •     grass and tree pollen (hay fever)
  •     dust mites
  •     animal dander (tiny flakes of skin or hair)
  •     food allergy (particularly fruits, shellfish and nuts)
If you think you have an allergy, you should see your doctor. A variety of tests exist to diagnose allergic conditions. These include placing possible allergens on the skin and looking for a reaction such as swelling. Blood tests can also be carried out to diagnose allergies.
