What is allergy?
An allergy is the response of the body's immune system to normally harmless substances, such as pollens, foods, and house dust mite. Whilst in most people these substances (allergens) pose no problem, in allergic individuals their immune system identifies them as a’ threat’ and produces an inappropriate response.
What causes allergy?
The most common causes of allergic reactions are:
- pollen from trees and grasses
- proteins secreted from house dust mites
- moulds
- foods such as peanuts, tree nuts, milk and eggs
- pets such as cats and dogs, and other furry or hairy animals such as horses and rabbits
- insects such as wasps and bees
- medicines
What Happens When You Have an Allergic Reaction?
When a person comes into contact with a particular allergen they are allergic to, a reaction occurs. This begins when the allergen (for example, pollen) enters the body, triggering an antibody response. When the allergen comes into contact with the antibodies, these cells respond by releasing certain substances, one of which is called histamine. These substances cause swelling, inflammation and itching of the surrounding tissues, which is extremely irritating and uncomfortable.
Common symptoms associated with allergic conditions include:
- sneezing
- wheezing / coughing / shortness of breath
- sinus pain / runny nose
- swelling
- itchy eyes, ears, lips throat and mouth
- sickness, vomiting & diarrhoea
How Do I Manage My Allergy?
The first step in managing an allergy is identifying the cause(s) of the problem.Here are 3 key things to remember when it comes to managing your allergy:
- Documenting where and when a reaction occurs
- Reducing the risk of an allergic reaction by avoiding the allergen, wherever possible.
- Medical treatments to reduce symptoms including medications and immunotherapy.
