NCT ID NCT07662083
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a non-invasive device that gently stimulates a nerve in the ear can improve symptoms and quality of life for adults with constipation-predominant irritable bowel syndrome (IBS-C). Participants use an ear clip for 30 minutes daily over 60 days. The trial compares active stimulation to a sham device to see if the treatment reduces pain, bloating, and bowel discomfort.
