The procedure of transferring stool to a patient — technically called
fecal microbiota transplantation — was first
performed in the United States in 1958 to treat an intractable case of C. difficile colitis, a gastrointestinal condition caused when the balance of microbes in the gut — called the microbiome — is destabilized or destroyed.
After the Mayo Clinic in Scottsdale, Arizona,
performed its first
fecal microbiota transplant in 2011, a patient who had been bed - ridden for weeks left the hospital 24 hours later.
