My 84 year old father has IBS and has recently been complaining of unusual abdominal pains and telling me "something isn't right." An abdominal ultrasound came back normal and now he is being sent by his GI doctor for breath testing, which is done to determine SIBO and a variety of other gastrointestinal disorders:

I was wondering if anyone here has had this testing done for SIBO or other disorders, and if so whether it was helpful as a diagnostic tool.
