On the back of this he ordered some blood tests which included Coeliac. Having read up on it, it seems to fit a lot of his symptoms (pale, sloppy poo for as long as I can remember, picky eater, insatiable appetite for carbs) but I realise there are A LOT of symptoms with CD. He is also quick to melt down. And I guess the trigger for the appointment was when my mum pointed out it wasn't normal to be buying a double buggy for a 4 year old...but I was sick of trying to push/carry him and DS2 who is 23m.

Anyway, I got a copy of is results and although Ttg was

Just to add for reference: his bloods show him to be mildly anaemic, low sodium (can't fathom why, doc said it would be something or nothing ) low monocytes and low lymphocytes.
