NCT ID NCT03603730

First seen Jun 27, 2026 · Last updated Jul 07, 2026 · Updated 3 times

Summary

This study tests whether a mild electrical pulse to the ear (taVNS) can change how the brain and stomach interact in people with chronic indigestion or gastroparesis. Researchers will use brain scans and stomach electrical readings to see if the stimulation helps. The goal is to find a new, drug-free way to ease stomach discomfort.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
auricular transcutaneous vagal nerve stimulation (taVNS) device
What this could lead to
If it works, this could point toward a non-drug, ear-stimulation treatment for chronic stomach discomfort and bloating.
What could go wrong
This is an early exploratory study with only 65 participants, so results may not apply broadly. The stimulation may not produce meaningful symptom relief.
