Explaining Fecal Transplant

In this segment from his book Brain Maker, Dr. David Perlmutter explains fecal microbial transplantation (FMT) as a method to regenerate and reset a compromised gut microbiome. He notes that FMT has been used for many years in the United States to treat Clostridium difficile infection, with more than 150 hospitals employing the procedure. Perlmutter discusses the emerging interest in applying FMT to other conditions where the gut microbiome is disturbed, specifically mentioning autism and multiple sclerosis as examples under investigation. He emphasizes that such uses are not yet mainstream, are not FDA‑approved, and he does not perform FMT in his own clinical practice. The purpose of highlighting FMT in Brain Maker is to explore its potential as a powerful tool for microbiome restoration.
