Gut nerve study aims to decode stomach paralysis

This observational study measured how the autonomic nervous system responds to eating in people with gastroparesis (a condition where the stomach empties slowly) and healthy volunteers. Researchers used a device to track heart rate changes as a proxy for nerve activity. The goal was to establish what normal and abnormal gut nerve function looks like, which could guide future treatments like vagal nerve stimulation. The study was terminated early, but data from 43 participants may still inform future research.
