Oral Sodium Sensor for Hypertension Management

JAMA. 2018;320(2):127. doi:10.1001/jama.2018.8979

Tracking salt consumption in patients with hypertension is difficult, but a new oral device for real-time monitoring of sodium intake could help to change that. Researchers led by Woon-Hong Yeo, PhD, at the Georgia Institute of Technology recently described their sodium sensor in the Proceedings of the National Academy of Sciences.

Patients with hypertension currently monitor their sodium intake by checking nutrition labels or entering their meal histories into smartphone apps. This approach doesn’t accurately capture salt intake, making it difficult for patients and their physicians to manage high blood pressure. That’s a big problem, as research suggests that the average sodium intake in the United States is more than double what’s recommended by the National Institute of Medicine.
