A new wearable device may help doctors identify hidden hormone patterns behind high blood pressure, according to researchers at the University of Bristol whose work was published on August 26, 2026. The study focused on primary aldosteronism, a hormone disorder that can affect up to one in five people with hypertension and raise the risk of heart disease, stroke and diabetes.
Non-invasive monitoring could change how hypertension is investigated
The research suggests that wearable monitoring could offer a simpler way to spot a condition that is often missed in routine care. At present, patients with suspected primary aldosteronism typically need more specialised testing, which can delay diagnosis and treatment. By detecting hormone patterns more directly in everyday settings, the device could make screening more accessible for people with difficult-to-control blood pressure.
The study was published in Science Translational Medicine, and the researchers say the approach has the potential to improve understanding of how hormone signals vary over time. That matters because blood pressure is not only influenced by lifestyle and medication, but also by biological mechanisms that may remain undetected without targeted testing.
Why the finding matters for NHS practice
High blood pressure is one of the most common long-term conditions managed in the UK, and earlier identification of secondary causes can help clinicians choose more effective treatment. If further research confirms the findings, wearable-based testing could support faster referrals and more precise care for selected patients in the NHS.
The work was supported by multiple funders, including the UKRI Biotechnology and Biological Sciences Research Council, the Medical Research Council and University Hospitals Bristol and Weston NHS Foundation Trust, underlining the UK relevance of the research.
Researchers will now need larger studies to show how well the device performs in broader clinical settings and whether it can be integrated into routine hypertension pathways. For now, the study points to a promising step toward easier detection of an often overlooked cause of high blood pressure.
