Positives

• An ME/CFS patient reported a remarkable recovery from a ten-year illness after ten consecutive fecal transplant treatments, with improvement persisting at follow-up Health Rising.
  
  
• A fibromyalgia case report documented gradual symptom improvement after FMT, with the patient reporting full recovery nine months after the last treatment SCIRP.
  
  
• In SIBO and IBS clinical experience, increasing fecal transplant dose from 30g to 60g raised response rates — supporting the clinical pattern that properly-dosed protocols outperform under-dosed home regimens Health Rising.
  
  

Negatives

• The first FMT study in ME/CFS was light on methodology and has not been replicated — no other formal studies have been completed yet, leaving the field with promising but unconfirmed signals Health Rising.
  
  

Hurdles & Side Effects

• Outside C. difficile infection, FMT is not FDA-approved in the US, so ME/CFS or Long COVID patients pursuing it must travel internationally (commonly to The Taymount Clinic in the UK or Bahamas) at out-of-pocket costs of $5,000-$15,000 per protocol MEpedia.
