Thanks to your expertise and diligence in checking everything when the provisional diagnosis of SIBO didn't quite ring true with you, I was officially diagnosed with Exocrine pancreatic insufficiency (EPI) (after a second sample was taken for confirmation at the GP). I'm really grateful for you finding it as I don't know where I'd be otherwise!
