I had someone contact me last week on behalf of a woman who had just been diagnosed with coeliac (wheat/gluten intolerance) on top of having Type 1. Boooo hiss. Totally not fair. I remember being at kids camp a couple of years ago and there were several kids there who had the two. Camp were brilliantly prepared, often with two different queues for kids with “just” T1 and those with coeliac as well. I also remember Elissa Renouf at DYNZ conference last year saying that a couple of her kids have both and they have to have special gluten free jellybeans for hypos – gah!

Apart from “they’re both auto-immune conditions”, I know nothing about the connection between the two so I thought I’d do a bit of googling on the topic. I read several articles, but this one was the easiest to digest.

Essentially:

  • Research has found that coeliac disease is five to 10 times more common in people with type 1 diabetes than in the general population
  • “The overlapping genetic variants occurred on regions of chromosomes (parts of cells that carry genetic code) that are believed to regulate the gut’s immune system” – that is, some of the genes which affect how the gut works are different (to regular genes) in both T1 and coeliac patients
  • This has raised the question of whether eating wheat/gluten in those pre-disposed to diabetes might actually trigger the onset of T1.

I did a little bit more searching and it appears that studies on non-diabetic mice have concluded that -

a) Non-diabetic mice fed a gluten-free diet were less likely to develop T1 diabetes.

b) Those on a gluten-free diet who did develop T1 did so later in life.

Hmmmm – all interesting stuff – but as yet obviously not proven widely enough to be an absolute fact.

What are your personal experiences and thoughts on this, people?
