The purpose of FMT is to reintroduce a patient’s gut with the healthy bacteria needed for proper gut function. It has famously been used to treat clostridium difficile, with over a 90% success rate. It can similarly treat other GI problems, but it can even be used for treating the symptoms of neurological conditions. Patients with neurological conditions have an overarching similarity in that almost all of them develop GI problems (such as constipation, diarrhea, IBS, etc) in addition to their other symptoms. HMT helps these patients relieve these symptoms, but it has also shown to mitigate some of their other symptoms not related to the GI tract. This has been credited to the brain-gut connection, which science is finding out holds a much stronger connection than previously thought.
