Hi. I had a blood test as I was suffering extreme acid reflux and it showed that my thyroid gland is only just functioning..it does run in the family and I'm to be retested in Jan to see if it has failed completely. But I've recently found out my grandad has crohns disease and due to the fact I'm getting horrid tummy aches generally feeling unwell and very tired. How do I go about asking my doctor if I can be tested for crohns. My grandad eventually died of bowel cancer probably linked to his crohns..so I'm a little panicked. Am I being silly and stressing over nothing. Would my doctor even listen?
