I have Sjogrens and gut problems, IBS is common with Sjogrens. If you are a
coeliac its likely you will have severe smelly diarrhoea
and a problem keeping your weight on. If you do cut out wheat, rye and barley totally from your diet it would be safer totalk to a dietition to make sure your diet is balanced withoutthe nutrients that these foods normally supply. There is a blood test which would indicate if you are a coeliac, but you need to be still eating gluten when tested.
