My son has had stomach issues for the last five weeks or so - ongoing nausea, stomach aches, constipation. He has been in tears going into school every day this week because of feeling ill, but apparently he perks up during the day. I feel really bad sending him in regardless, but he cants stay off every day, and he seems fine much of the time. We have so far been to the GP twice - the first one diagnosed constipation and prescribed movicol. The second time I asked for a blood test for coeliac, because quite a few people in my family have it (though I've never been tested). The GP was quite dismissive and googled coeliac and said that if he had it he would have diahorrea, not constipation, but he did agree to the test (we haven't managed to get the test done yet). He advised to up the dose of Movicol and said we would review after the bloods were done. DS does seem to be pooing more regularly now but still feeling really unwell so much of the time. He is quite small and skinny for his age, despite having tall parents, and eating loads.
Does anyone know whether this sounds like it could be coeliac? Or any other suggestions? We have wondered whether it could be connected to anxiety about school, but he says nothing is bothering him about school. Can coeliac develop so suddenly aged 8? Can he inherit it even if a parent doesn't have it? The GP said if no first degree relative has it he is less likely to have it, although my grandmother, aunt and uncle all have/had it.
