Q: For a few years I’ve suffered with bloating, colicky abdominal pains and occasional diarrhoea. I also get a dull headache and feel as though I have no energy. My GP did some blood tests for anaemia and coeliac disease, which came back normal, so my GP said it’s probably irritable bowel syndrome. I tried a gluten-free diet anyway and felt much better. The brain fog and irritability lifted, too. But when I ate a slice of bread the symptoms returned, only settling after a few days back on a gluten-free diet. Could I have coeliac disease after all?
