Wearable Device Detects Nighttime Hormone Surges Causing Undiagnosed High Blood Pressure

A new study using a wearable hormone‑monitoring device has identified pronounced nighttime surges in aldosterone, a hormone that regulates blood pressure. The device, worn continuously for several days, recorded hormone levels in real time and revealed that many patients with hypertension exhibit sharp increases in aldosterone during the night that are not captured by routine daytime blood tests.

The findings shed light on why primary aldosteronism—a common, treatable cause of high blood pressure—often goes undiagnosed. Standard screening protocols typically involve a single blood sample taken in the morning, which can miss the nocturnal spikes that drive the disease. By capturing the full 24‑hour hormone profile, clinicians may be able to identify the disorder more reliably and initiate appropriate therapy earlier.

If validated in larger trials, the wearable technology could become a valuable tool for clinicians seeking to improve the detection of hormone‑driven hypertension, ultimately leading to better patient outcomes and more targeted treatment strategies.
