There are some people that have taken weaker Antibiotics that have developed SIBO. I think it depends on the strength,type, and the duration of the Antibiotic of whether they can develop more severe candida.
Its not the absolute truth but
the majority of our immunity(gut flora) still resides in our gut.
For people that have the majority of the candida under control in their gut the next step would be to try to fine tune their immunity/immune response.
