    Procedure DIY FMT Beginner's Questions

    Wherever you read that is a low-quality source of information because that's not correct. The wiki covers FMT prep: https://humanmicrobiome.info/fmt/

    Blog The FDA and FMT regulation, part 2. (Jul 2024, HumanMicrobes.org) I met with the FDA. Here's what I shared with them, and their response.

    Looking at the link, there doesn't seem to be a way to send it to anyone. It looks like just another petition site, and there's already a petition. It's also missing context and citations, so it doesn't seem like a useful thing to send to anyone, as it assumes that people will already be...

    Is a lot of probiotics the same as FMT? Anyone try VSL 3? I’m trying a high dose (around 230 billion CFU daily)

    If you take FMT that lackadaisically, you're likely to get worse. What you listed is not how you select & screen a donor. https://humanmicrobiome.info/fmt/ This does not exist.

    Not even close. Probiotics can be, and often are, highly disruptive. https://humanmicrobiome.info/probiotic-guide/ In large part, the opposite of FMT.

    I’m terrified and don’t want to eventually develop a horrible disease, my gut is ruined! Help!

    Did you review the wiki? https://humanmicrobiome.info/testing/ That's generally correct. This is misleading to the point of being misinformation. Presumably they have already seen a doctor and ruled out other causes. It is very rare that something like this is not related to the gut microbiome.

    FMT and COVID-19, vaccines. Any concerns about COVID vaccination affecting FMT quality? Does it matter if the donor is vaccinated?

    FMT and COVID-19, vaccines. Any concerns about COVID vaccination affecting FMT quality? Does it matter if the donor is vaccinated?

    One should be extremely cautious, especially because, in my opinion, there are no safe sources of FMT right now. But further discussion of that in this thread is off-topic.

    FMT and COVID-19, vaccines. Any concerns about COVID vaccination affecting FMT quality? Does it matter if the donor is vaccinated?

    The wiki has a page on this that includes a section covering vaccines' impacts on the gut microbiome: https://humanmicrobiome.info/immune-system/ There's a good quote from researcher Rob Knight. There are much more important considerations when selecting a donor.

    Small intestine/upper GI SIBO YOGURT

    Certain strains of it. Are there specific human-sourced strains that people use for "SIBO yogurt"? You clearly didn't read and understand the citation. That's really low-quality evidence. But sure, the potential benefits likely outweigh the risks for "L.Reuteri and L.Gasseri yogurt".

    FMT The Super-Donor Phenomenon in Fecal Microbiota Transplantation (Jan 2019, review)

    Citation needed. This is not the simple task widely claimed. See the probiotic guide: https://humanmicrobiome.info/probiotic-guide/#fermenting-your-own-probiotics-at-home This is silly. No probiotic comes close to FMT. No. The onus of proof is on the person making the claims. Given that SIBO...

    Worse after FMT from a hospital

    Extremely unlikely. This is why I've spent the past 10 years warning people about using low-quality donors, and the poor donor screening & selection at hospitals, clinical trials, and stool banks.

    Worse after FMT from a hospital

    In general, it seems like the only way to recover from a bad FMT is to do FMT from a better donor. Where did you get the FMT? From a hospital, using their donor? They did it for IBS? Was it part of a clinical trial?

    Donors Does stool donor sex and age matter? Are there differences in receiving fecal transplants (FMT) from male vs. female donors? And different age groups and enterotypes? Donor matching

    If you mean studies supporting your claim, you need to cite them. As you note, I already commented on that anecdote and debunked the claim.

    Donors Stool donor with family history of colon cancer

    What criteria? https://humanmicrobiome.info/cancer/ You can see there is plenty of basis for concern that you may "transplant a biome that supports the development of cancer". It's largely unknown. FMT is all about risk vs reward, and family history is an added risk.

That's irrelevant to whether it's his responsibility. He is the head of numerous agencies that should be solving the problem...
