I never thought gas was a big deal either until post j pouch surgery. It's annoying as hell now. Besides your diet, there's no real cure for it. And even trying to eat the right foods leaves a lot to be desired. The problem is before your surgery your gas had a huge colon all it itself. With all that space and room if it made any noise, it didn't bother you much. But now that your colon is gone your gas has gone through the equivalent of moving from a huge mansion to a studio apartment.
