FDA Warns Against Non-Invasive Blood Glucose Monitoring Devices

The agency has not approved any smartwatches or rings for blood glucose measurement, citing potential risks and inaccuracies.

The U.S. FDA has issued a warning against using smartwatches and smart rings that claim to measure blood glucose levels without piercing the skin, stating that no such device has been authorized, cleared, or approved.
The warning highlights the potential risks of relying on unauthorized devices for blood glucose measurement, including inaccurate readings that could lead to dangerous medication dosages.
Several companies are reportedly working on non-invasive blood glucose monitoring technology, but none have yet received FDA approval.
The FDA's caution does not apply to smartwatch apps linked to FDA-approved continuous glucose monitoring systems that measure blood sugar directly.
Despite the FDA's warning, some articles express hope that future developments in technology will eventually lead to reliable non-invasive blood glucose monitoring devices.
