Summary

This study tests whether fecal microbiota transplantation (FMT) can help children and young adults with autism who also have stomach issues. FMT involves transferring healthy donor stool into the patient's gut via colonoscopy. Researchers will track changes in gut and autism symptoms, as well as emotional and behavioral improvements, in 60 participants aged 7 to 30.
