Clinical application of fecal microbiota transplantation and its influencing factors

Year: 2026

Type: article

Abstract: Fecal microbiota transplantation (FMT) is an emerging therapy that has received significant attention in recent years, although its origins can be traced back to 4th-century China. In modern medicine, FMT has been incorporated into clinical guidelines for the treatment of recurrent Clostridioides difficile infection. By re-establishing a healthy gut microbiota and regulating the immune system, FMT has potential therapeutic effects on various diseases, such as gastrointestinal diseases, diabetes, tumors, Alzheimer’s disease, and liver disease. However, its efficacy varies based on the type of disease and individual differences. The clinical application of FMT is influenced by multiple factors, including fecal matter processing, administration route, dosage, donor screening, and recipient detection. Currently, FMT faces numerous challenges, including the need to verify the stability and durability of its efficacy, standardize donor screening criteria, and optimize fecal processing and administration. Future research is expected to reveal the mechanisms of action of FMT, optimize treatment protocols, and refine its safety, efficacy, and convenience, thereby bringing hope for patients with complex and challenging diseases.
