The elemental diet for SIBO is typically VERY effective at reducing gas. When I'm in a UC flare I have tons of gas, no matter what I do. That said, there may be some 'die-off' symptoms you're experiencing such as gas, discomfort.
Those of us with UC in combination with SIBO are a bit more complicated. Though SIBO treatment can dramatically help UC symptoms, it isn't actually the cause of our UC. Therefore, treating SIBO can be more hit-or-miss with regard to efficacy.
I urge you to consider that some of the symptoms you're experiencing are direct from the UC condition, and less from SIBO, hence the lack of improvement with the elemental diet. Also, don't rule our the possibility of C. Diff, especially if you have undergone antibiotic therapy (prescription or herbal) in the recent past (I dont think you mentioned when, so I figure better safe than sorry).
Anyway, I hope you feel better soon, and that you find some answers! Good luck!
