GI-Challenge Study for Gastroparesis Patients and Healthy Controls

NCT03896126 · Status: TERMINATED · Type: OBSERVATIONAL · Enrollment: 43

Last updated 2025-09-04

No results posted yet for this study

Summary

Gastroparesis Patients and Healthy Controls ages 20-49 will be asked to participate in an observational study measuring vagal activity following food ingestion in order to establish parameters of autonomic nerve/vagal function in healthy human subjects compared to those with gastroparesis. Information generated from this study may be used in the future to establish what is normal and abnormal enteric vagal tone and how much vagal nerve stimulation treatment may be required to help patients with gastroparesis.

Conditions

Interventions

OTHER

Observational

There is no intervention. This is an observational study attempting to establish parameters of normal and abnormal vagal tone in healthy control and gastroparesis patients, as there is currently no metric to determine what dose of vagal stimulation is required to treat gastroparesis.
