FDA warns against using smartwatches and smart rings to measure blood sugar

The US Food and Drug Administration (FDA) has issued a warning about the risks of using smartwatches and smart rings that claim to measure blood glucose levels without piercing the skin. The FDA has not authorized or approved any such devices, as they can provide inaccurate measurements and lead to errors in diabetes management. The agency advises individuals relying on accurate blood glucose measurements to consult their healthcare providers for FDA-authorized devices. Smartwatch apps that display data from FDA-approved continuous glucose monitoring devices are not affected. The FDA is taking measures to prevent the illegal marketing of unauthorized devices. Consumers can report any issues through the FDA MedWatch Voluntary Reporting Form.
