After 5 years of living hell my 4th GI consultant has mentioned the possibility of being referred to St Marks in Middlesex where they have a specialist GI department that accepts national referrals. I have been through every test you can name plus dietary advice (including FODMAP) with no success. The only things I eat are plain boiled potatoes and grilled lean meat (no seasoning) and drink only water. If anyone has any experience of this hospital would love to hear it-with several months between appointments I fear it will be 2014 before I get to a "super specialist" but fingers crossed they can help. I am at the end of my tether.
