Hi! I had some blood work done a couple weeks back, as I've been feeling constantly tired and lethargic and it's making my 9-5 job really uncomfortable. The blood test (it was a fasting test, done in England with the NHS) came back all negative, so the docs can't help me out. It struck me last week that I feel most tired after eating lunch- and I always have a sandwhich which... you guesedt it- contains gluten. As of today, I'm going on a 2 week no gluten trial- but I was wondering if anyone knows if a regular fasting test examines gluten intolerance? In which case I should probably look at something else. Thanks! P.S. Oh, I've had IBS for about 6 years now.
