- Fecal microbiota transplants, used to restore gut health, involve transferring stool from a healthy donor to a recipient.
- A new University of Chicago study in mice reveals potential long-lasting, unintended health consequences from these transplants due to microorganisms colonizing the entire intestinal tract, creating regional gut mismatches.
- The study found that transplanted microbes altered intestinal environments, affecting metabolism, behavior, energy balance, and liver function in mice.
- Researchers advocate for caution and suggest using microorganisms from all regions of the intestine, not just the colon, for transplants.
- Dr. Eugene Chang, the study's senior author, notes that fecal microbiota transplants can cause changes in host-microbe relationships in different bowel regions that may be difficult to reverse.
