SIBO and IMO are definitely not shams. The basic problem is that SIBO results from different causes for various individuals, and the medical community is sorely lacking insight- many doctors have still not even heard of these conditions, and thus have no solutions. Other doctors swimming in this sea of ignorance prescribe treatments they hope will work as a shot in the dark. At this point in my own case, I've found that I know more about it than the doctors I've consulted. This leaves an open field for all manner of charlatans looking to make a buck.

A woman in Australia, Bella Lindemann, runs a clinic that focuses on IMO and SIBO and she has the best understanding of anyone I've found, but she no longer works with individual clients. She has posted multiple videos, writes a blog, and has assistants who conduct teleconferences worldwide. I tried that route until I realized that my assistant was providing just copy-and-paste generic advice, some unrelated to my own case- cost me several hundred $ before I pulled the plug. If you read her blogs you should come away with a deeper understanding and you may be able to help yourself. I was able to cure my IMO, still working on the underlying SIBO. In my case, since there are no other abnormalities, a lifetime of stress is almost certainly behind my SIBO- a conclusion reached after a whole bunch of lab tests, all on my dime. I know which bacteria strains are the culprits and which are not. But there is no treatment for specific bacteria. I also know that the several side effects that have circumscribed my life are due to my immune system's interpretation of the overgrowth as an infection (it's not). Read my previous posts here for more of the sordid details.

Fun fact- the ancient Greeks figured out that most infirmities originate in the gut.
