Is FMT recommended?
In studies of Clostridium difficle enterocolitis, frequent relapses of bacterial overgrowth occur when the individual’s intestinal gut microbiome has been depleted to about 70% of the natural bacterial species number. Treatment of this requires a fecal microbiota transplant (FMT), commonly referred to as a human stool transplant. Most studies of FMT in patients with higher levels of biodiversity (>80%) seem to have little to no benefit. The majority of the biodiversity of studies in children with autism or developmental problems do not indicate severe depletion of biodiversity. Because of this, I do not recommend FMT. Many children under my care have received FMT and it did not seem to improve their pace of neurological recovery.
