From my light readings on SIBO, a periodic antibiotic "cure" is recommended. I can't remember if there is a diet change recommendation. I was tested for SIBO and came up negative; the doc wants me to do another, perhaps more sensitive (and expensive) SIBO test, but I just don't have any SIBO symptoms (I have IBS-C and the "C" doesn't seem to be SIBO at all).

I feel for you -- a persistent flare up is no fun at all. I didn't go into it at length, but I have to eat the Monash App-listed zero or trace FODMAP foods to get relief, and not too much of any one thing or too much food at once. Overlay that with no lactose and no grains (even rice bothers me), enough sleep, and reduced stress -- then I do just fine, which is better than no path to that outcome.

I would love a solution that doesn't require me to limit my food so much but I haven't found one yet.
