… The authors of the piece refer to a study (due to be published) in which 920 patients with symptoms of irritable bowel syndrome (e.g. abdominal discomfort and bloating) have wheat (as well as other foods including cow’s milk) removed from the diet . On blind challenging with food (participants did not know what food they were being challenged with), a full third of patients responded adversely to wheat and not with placebo. As the authors say:
The evidence therefore suggests that, even in the absence of coeliac disease, gluten based products can induce abdominal symptoms which may present as irritable bowel syndrome.As a result of this and other evidence, non-coeliac gluten sensitivity was recognised earlier this year by a group of 15 international experts . Common symptoms that are attributed to this condition include “intestinal symptoms such as abdominal discomfort, bloating, pain, and diarrhoea (also consistent with irritable bowel syndrome) or with a variety of extra-intestinal symptoms such as headaches, “foggy mind,” depression, fatigue, musculoskeletal pains, and skin rash.”
The authors conclude:
For patients who report wheat intolerance or gluten sensitivity, exclude coeliac disease… and wheat allergy…. Those patients with negative results should be diagnosed with non-coeliac gluten sensitivity. These patients benefit symptomatically from a gluten-free diet. They should be told that non-coeliac gluten sensitivity is a newly recognised clinical entity for which we do not yet fully understand the natural course or pathophysiology.I am almost speechless at the balanced and honest nature of this account of gluten sensitivity: it recognises the limitations of medical testing and admits there’s things we simply don’t know or understand. I have a feeling there’s going to be plenty of people reading this who will feel inclined to shove these findings in the face of a practitioner who told them their tests were negative and that their wheat sensitivity is imagined and ‘all in their mind’.
