Fecal Microbiota Transplant (FMT) Donor Screening Questionnaire

Check the intro page to understand the importance of these questions, and for lots of info on the microbiome. Evidence throughout this wiki shows that nearly any condition can be transferred or cured via FMT.

The gut microbiome impacts/regulates the entire body. It is shaped by genetics, and affects genetic expression. Happiness, intelligence, & athleticism are some of the best signs. Younger is typically better since dysbiosis increases with age, and is looking to be the cause of most diseases associated with aging, including aging itself. The ultimate stool donor is probably something like a 2-18 year old Michael Jordan, or a guy like this who is both physically and mentally very fit:

Myron Rolle

Keep in mind there are numerous highly accomplished athletes who wouldn't qualify. And there are many unaccomplished athletes, and even non-athletes, who would. HumanMicrobes.org has a blog post that expounds on this. They are screening millions of applicants to try to find highly effective stool donors.

This questionnaire is not exhaustive. If you think of something else please include it. If there is something you don't want to disclose then please state that, instead of being untruthful about it.

For example, one person contracted their donor's sweet tooth, another person started having sleeping trouble after their FMT, a man experienced his mother's menopause symptoms when doing FMT from her, others have contracted obesity from their obese donors, depression from their depressed donor, others have reported hair loss or hair regrowth, others contracted dermatitis, another contracted their donor's cramping issues, ear issues, some body odors, food intolerances, etc.

And even if you don't transfer a specific condition, you transfer a dysbiotic gut microbiome which can have all sorts of detrimental effects. FMT is all about the risk-vs-reward ratio. Low-quality donors have a higher chance of harm and a lower chance of benefit. And the opposite for high-quality donors.

Currently I believe kids are ideal stool donors for 3 reasons:

  1. Dysbiosis increases with age, often including an onset at puberty.
  2. Less likely to have taken antibiotics.
  3. They're unlikely to have picked up an STD.

Babies/toddlers might work but are a bit more risky since it's harder to judge their health & development till they get closer to adolescence. For these cases the health & diet of the parents becomes more important: https://humanmicrobiome.info/maternity

It is probably generally a bad idea for parents to be stool donors for their kids, but there are some reports of parents being effective donors for their kids. The reasons include:

  1. Much of the microbiome is heritable, so if a child has a dysbiotic gut there's a good chance they inherited that dysbiosis from their parents. See Origins and Maternity.
  2. Dysbiosis increases with age. https://humanmicrobiome.info/aging
