If you or a loved one has been diagnosed with ‘atopic’ eczema or dermatitis you might be wondering what the ‘atopic’ bit means.
Basically, atopy is the term used to describe those people who develop allergic conditions including allergic rhinitis (including hay fever), asthma and atopic dermatitis/eczema (AD). It usually means that the diagnosed individual has greater immune response, or ‘atopic reaction’ to common allergens including environmental triggers such as pollen and grasses etc.) and food.
Atopy versus Allergy
Atopy is a Type I hypersensitivity reaction, which means that there is an immediate hypersensitivity to an antigen which results in an over-exaggerated IgE mediated immune response. Allergies are an exaggerated immune response regarding of the mechanism. This means that whilst all atopic reactions are considered allergies, not allergies are considered atopic.
Could Irritable Bowel Syndrome (IBS) be atopic?
In 2008 scientists published a paper naming a new subtype of IBS, atopic IBS (1). More recent studies appear to confirm the connection between atopy and IBS, with those diagnosed with atopy being at much higher risk for IBS and even Intestinal Bowel Disease. (2,3)
Which symptoms are linked to atopy?
Nutrition and atopy
Nutrition to support an atopic medical diagnosis will need to be individualised to the food or environmental triggers involved and the specific atopy – skin, gut, lung etc.
