An alternative to that may be trying to get stool from humanmicrobes.org or a more "legit" way which is through the center for digestive diseases in Australia. I don't know if FMT's are helpful for all IBS patients (the research is not there yet) but anecdotally it seems like the most desperate IBS patients end up trying it to varying efficacy. I can't recommend FMT as I'm sure everyone's pathology is different and there are more traditional therapies that may work such as low FODMAP, rifaximin, or meds that increase/decrease intestinal transit time. For me, all of those therapies are embarrassingly ineffective and I think that IBS patients should at least know that FMT therapy is a thing; since it has lead to remission for many community members which gives hope that there may finally be a treatment for the most desperate.
So the FMT helps in my case as well as the BPC-157 which someone else linked in the comments. I was quite surprised when my resting heart rate and blood pressure returned to my pre-disease levels within a day or two of starting the peptides. I have probably tried 3 or 4 dozen drugs at this point (mostly doctor recommended but also some from my own research); none to any effect, so seeing quick results from this new compound was shocking. I now also have more of type 2-3 stools rather than the unescapable type 1 that has plagued me ever since the diseases' inception. So that's good. I've only been using the peptides for a month so don't know what to expect. I am hoping if I can mega dose with some FMT and keep using the peptides maybe I could get into remission. Who knows. Luckily I am able to function as an engineer again for the first time in years (the brain fog is less remarkable now) so I am hoping things will return to normal but only time will tell. I hope this information is helpful but feel free to reach out if you have questions or just would like to chat because I know how lonely and lost in translation these type of health maladies can be.
Anyways, if I am taking a lot of fecal matter and using the peptides; the fallout I get from eating is not as bad. There are still other issues, but it seems to work at at least within a few days with the fecal matter and instantly with the peptides. Very sadly, I've noticed the benefits go away pretty quickly once I stop using each treatment as well. It really is a nightmare, but I am sure others have it worse.
Just googling now it seems there is no real test for IBS. How did you know that was the cause? Also, I've taken peptides before for different reasons, which ones helped you with your stomach?
That sounds like you're (involuntarily) on a CRON diet; calorie Restriction optimal nutrition.
