Is sibo curable? can it ever go away with antibiotics and never come back?

Yes, but maybe no...: If you have ibs due to sibo (small intestinal bacterial overgrowth)--antibiotics like xifaxan (rifaximin) may help. Sibo may also occur from anatomic variations in the small bowel, altered small bowel motility, or a variety of systemic conditions that prevent permanent cure (e.g. The bacteria just grow back).

It depends: It depends upon the cause. Try probiotics and prebiotics like acidophillus, Florastor, Activia yogurt, for example as well. " Rifaximin is probably the only antibiotic that is capable of achieving a long-term favourable clinical effect in patients with irritable bowel and SIBO[43]." from article below. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2890937/
