AI-Powered Wearable Device Revolutionizes Gut Health Diagnosis

Similar to the heart, the gut generates electrical currents, though much weaker—about 100 times less intense. Alimetry’s (Auckland, New Zealand) advanced wearable device detects these subtle electrical signals from the skin's surface using Body Surface Gastric Mapping, which functions similarly to an ultra-high-resolution electrocardiogram (ECG). The Gastric Alimetry system records these signals as patients eat and digest meals while logging symptoms via an app. The collected gastric data is transmitted to the cloud, where it is analyzed by AI-powered algorithms, and trained on a vast array of test cases to improve accuracy and performance. The outcome is an auto-generated Gastric Alimetry Report, providing clinicians with objective, data-driven insights to guide diagnosis and the development of personalized treatment plans.

Gut health issues can stem from a variety of sources, such as diet, diseases, and the vagus nerve (physiological causes), or from factors like stress and the gut-brain axis. Having a comprehensive platform that can assess all these factors simultaneously is a major breakthrough for clinicians. The Alimetry platform tracks both physiological data and symptoms, integrating gut-brain health questionnaires within the app, allowing healthcare providers to transform a complex, unclear clinical picture into a precise diagnosis. This facilitates personalized medicine tailored to the individual’s needs. The device and platform, which received FDA approval for clinical use, were rolled out in the U.S. market after a controlled release in 2022. Over 40 hospitals and clinics worldwide have adopted the device.

"Alimetry was designed to introduce clarity into a field that has involved lengthy, uncertain diagnostic journeys. It gives clinicians the tools they need to quickly and correctly diagnose patients so that we can move on from trial and error - and guesswork - into clarity of care and personalized medicine," said Alimetry chief executive Dr. Greg O'Grady.
