A wearable device developed in Bristol has revealed hormone patterns that routine blood tests can miss, potentially improving of a common cause of high blood pressure.

continuously monitored 60 patients with primary aldosteronism, a hormone disorder to affect up to one in five people with high blood pressure.

The waist-worn U-RHYTHM device sampled hormones every 20 minutes while people went about ordinary life and slept at home. It revealed bursts of hormone production during the day and night that would be easy to miss in a conventional clinic test.

The proof-of-concept could help doctors identify the condition earlier and tailor more effectively. Sometimes the body is not hiding the clue. We have just been looking at it for too few minutes of the day.
