Mechanism of action

FMT works by transferring stool from a healthy donor into the gastrointestinal tract of a patient with dysbiosis, reestablishing beneficial bacterial populations and their metabolic functions. This restores microbial diversity and competitive exclusion of pathogenic organisms, particularly Clostridioides difficile. The restored microbiota produces short-chain fatty acids and other metabolites that support intestinal barrier function and immune homeostasis.
