Phase N/A

Fecal Microbiota Transplant (FMT) is a process where healthy bacteria from a donor's stool is placed into a recipient's gut to help restore balance. This study aims to track how safe and effective FMT and similar products are over time. It plans to include 4,000 patients from 75 locations in North America. Information about how FMT is done, and why it’s needed, will be collected.

Participants will be followed for up to 10 years to check on their health after the FMT procedure. They will have regular check-ins with their healthcare provider at 1 month, 6 months, 1 year, and 2 years, and will be contacted at least once a year.

  • Participants must be able to give consent and have internet or phone access.
  • Donors also need to provide consent and a stool sample.
  • People in prison cannot join the study.

Participation involves regular follow-ups, which help researchers learn how FMT works over time.
