I think they have stopped doing them in the UK.They just go straight to colonoscopy.SIBO is one of the many frustrating chicken and egg situations that comes with IBS. Even if you have SIBO you need to find out what has caused it. If you dont find the underlying cause then you can get rid of the bacteria with antibiotics but it will return. IBS may cause SIBO rather than the other way around.Do they do these tests in the uk? I'm really interested in SIBO, it sounds like something I should definitely be tested for.
