Allergy or Intolerance?

An allergy is the body’s immune system responding to what would normally be considered a harmless substance such as pollen, food, mould, pets’ hair, insects, medicines or house dust mites. The body perceives this substance to be a ‘threat’ and produces an inappropriate response, with symptoms usually starting within a few minutes but also as long as two hours later. Whereas a food intolerance is a difficulty digesting certain foods and experiencing physical symptoms as a result of eating them, with symptoms emerging hours to days later.

Remember:
Allergy = fast symptoms
Intolerance = symptoms emerging later

What is the difference between IgE & IgG4?

Our body’s defence system, the immune system, protects us from disease. Antibodies produced by the immune system are one method of protecting us from foreign bodies. They recognise and prevent bacteria and viruses from entering the body. The IgE class of these antibodies is responsible for allergic reactions. Lifelab IgE tests will provide you with results on certain allergies.

If you believe you have an allergy you will need an IgE test. If you believe you have an intolerance you will need an IgG4 test.

The IgG4 subclass is the least abundant type of antibody, and often needs building up. Intolerance reactions are usually subtler than IgE symptoms – and include headaches, nausea, stomach cramps, diarrhoea or constipation, fatigue, skin disorders and lethargy – but can cause long-term damage and chronic discomfort. Lifelab IgG4 tests will provide you with results for an intolerance.

  • What is Coeliac Disease?
  • Allergy & Intolerance prevalence in the UK
  • Food labelling
  • Post-test analysis: What is an Elimination Diet?

Coeliac disease is an autoimmune condition where the body mistakes the protein gluten, found in wheat, barley and rye, as a threat to the body and attacks it. This damages the lining of the small intestine producing inflammation and physical symptoms.

A staggering 44% of British adults now suffer from at least one allergy and the number of sufferers is on the rise, growing by around 2 million between 2008 and 2009 alone. Almost half (48%) of sufferers have more than one allergy (Mintel, 2010)

There are 14 foods which must be labelled and identified as ingredients on all pre-packed food:

Cereals containing gluten, crustaceans, eggs, fish, peanuts, soybeans, milk, nuts (almonds, hazelnuts, walnuts, cashews, pecan nuts, Brazil nuts, pistachio nuts, macadamia nuts), celery (including celeriac), mustard, sesame, sulphur dioxide/sulphites, lupin, molluscs

An elimination diet is the removal of foods, which have been identified as causing an allergic or intolerant reaction, from your daily diet.
