Allergies

Allergies can be caused by any number of factors – natural products are just as likely to cause reactions as man made.

The most common causes of allergies are:

Grass/tree pollen (Hayfever)
Dust mites
Animals
Food
Insect bites and stings
Medications
Mould
Household cleaners

Allergy Symptoms

Whilst the symptoms of allergies are unpleasant, they are often not serious and do not cause too much concern. However some reactions are serious and require immediate medical attention (please see below).

The most common symptoms of allergies are:

Sneezing or an itching/runny/blocked nose
Itchy, red, watering eyes
A raised, itchy red rash
Dry, red or cracked skin
Swollen lips, tongue or face – Be aware these can be early symptoms of a severe reaction

Severe Allergic Reaction (Anaphylaxis)

In very rare cases an allergy can be serious and can lead to anaphylaxis and/or anaphylactic shock which can be life threatening. This affects the whole body and occurs within minutes of being exposed

Symptoms include:

Swelling of throat and mouth
Difficulty breathing
Light-headedness
Confusion
Collapse and loss of consciousness

How to minimize the effects of allergies

Sometimes it may not be possible to identify what is causing an allergy, however if you are able to identify what is causing the allergy then the following advice may help:
Avoid contact with allergens where possible
Ask for accurate food content details of you have food allergies
Take antihistamines at times when you are likely to have a reaction
For patients who have severe allergies, they may be required to carry an ‘Epi-pen’ – this will be prescribed by a specialist and training will be provided on how to use them
