Leading researchers from Harvard Medical School and Brigham and Women's Hospital advocate for national stool banks. The concept: deposit a fecal sample in your younger, healthier years, preserve it, and use it later to restore your gut microbiome balance if needed.
Our gut hosts trillions of microorganisms essential for digestion, nutrient absorption, and disease prevention. Aging and modern lifestyles disrupt this delicate ecosystem, leading to significant microbiota shifts.
For years, scientists have studied fecal microbiota transplantation (FMT) to treat conditions like Clostridioides difficile infections (CDI) and inflammatory bowel disease (IBD). Promising results include curing colitis and even rejuvenating aged mice brains. Experts see broader potential against colon cancer, alcoholism, and more.
While donor FMT offers benefits, mismatches—such as transferring microbiota from non-industrial donors to urban recipients—can cause imbalances and risks.
Emerging research favors autologous fecal microbiota transplantation: using your own stool collected when young and healthy. This approach could effectively "rejuvenate" the gut microbiome.
The plan? Collect and cryopreserve stool from healthy young individuals for future autologous use. Though storage challenges exist, the payoff could be transformative: treating autoimmune conditions like asthma, multiple sclerosis, IBD, diabetes, obesity, heart disease, and even combating aging, say the authors. "We hope this sparks long-term clinical trials," they conclude.
