Smart ring tracks sleep and heart rate to guide weight-loss care — a trial puts it to the test
NCT ID NCT07736729
First seen Jul 30, 2026 · Last updated Jul 31, 2026 · Updated 1 time
Summary
This trial tests whether a smart ring that continuously tracks sleep, heart rate, and activity can help adults lose more weight during obesity treatment. Adults having weight-loss surgery or starting weight-loss medication wear the Oura Ring. In one group, the care team can see the ring data and use it to guide care; in the other group, the care team does not see the data. Researchers compare weight loss and health measures like blood sugar and blood pressure between the two groups.
