Transcutaneous auricular vagus nerve stimulation targets the brain-gut axis to treat functional dyspepsia: a scoping review of clinical evidence and mechanistic research
Background Functional dyspepsia (FD) is a common gut–brain interaction disorder with suboptimal response to pharmacotherapy. Transcutaneous auricular vagus nerve stimulation (taVNS), a non-invasive neuromodulation targeting the vagus nerve, has emerged as a promising brain–gut axis therapy. This scoping review (PRISMA-...
