Symptoms, Treatment & Advice
What is an Allergy?
An allergy is a disorder of the immune system which, causes an exaggerated response within the body when you come into contact with a foreign substance, that would be harmless in most people. The contact can be with your skin, mouth, gullet (oesophagus), stomach, intestine or with the lining of your lungs. Substances in the environment that cause the response are known as allergens and someone who suffers a response to a particular allergen is said to be allergic to it. If you are allergic to a particular allergen you may suffer from a mild cough or a sneeze attack, but for others the symptoms can be much more severe, and can even lead to death. Almost any substance can be an allergen for someone.
Allergies are generally the body’s way of eliminating something it considers unsuitable. Allergies are responsible for many illnesses, especially in young children. If you think you have an allergy, you must contact your doctor who will help you to control the symptoms.
What causes allergies?
An allergy occurs when the allergen in question e.g. pollen, triggers a reaction in the body of the individual. When the allergen comes into contact with the body, the immune system believes that the specific allergen is harmful and so produces an antibody called IgE (E-class Immunoglobin) to fight it. This antibody then triggers chemicals, including one called histamine to be released from cells (called mast cells) in our skin, lungs, nose or intestine, causing the various symptoms of an allergic reaction.
The most common allergens are as follows:
