Ear zaps may tune up your gut – healthy volunteers needed
NCT ID NCT07632378
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a mild, painless electrical stimulation on the ear can change how the stomach and upper gut move in healthy adults. Twelve volunteers will receive both real and fake stimulation in a random order during an 8-hour session. The goal is to see if this simple technique can trigger natural gut cleaning waves, which might one day help people with digestive problems.
