While neuromodulators are primarily used to treat psychiatric disorders, they can also help normalize symptoms of irritable bowel syndrome by targeting the gut-brain axis. In fact, about half of all patients with IBS have the potential to benefit from neuromodulators. Dr. Douglass Drossman joins Dr. Peter Buch to discuss his research on how various neuromodulators can provide relief for IBS patients. Dr. Drossman is the President of the Drossman Center of Education and Practice of Psychosocial Care and Drossman Consulting as well as a Professor Emeritus of Medicine and Psychiatry at the University of North Carolina School of Medicine.
