I have been Gluten Free now for a few years but still had attacks of stomach upsets and diarrhoea. I have been convinced there was gluten in something and have accused everyone and everything being the culprit until....I recently discovered SIBO which is caused essentially by too much bad bacteria build up in the small intestine, common in people diagnosed with IBS and with intolerances. I couldn't understand why I reacted to different foods and couldn't find a link until now - which for me is mainly Sugars (not just refined sugar) which are high in a lot of gluten free food and bread. Apparently sugars feed bad bacteria and cause them to multiply and neutralise the good bacteria causing SIBO. I have been taking a strong probiotic tablet in the morning (not a probiotic drink) and cutting down on my sugars and it's like a miracle. I know things don't work for everyone, but if there's someone like me out there that's still having problems on a GF diet, it's worth reading about it, particularly if you are older, like me and your gut doesn't heal as fast as young'uns! Anybody else had any experience of this?
