FDA Issues Warning on Using Smart Gadgets for Blood Sugar Monitoring

Smartwatches and rings can track various health metrics, like physical activity, sleep, heart rate, and even your heart's electrical activity. However, the FDA cautions against using these devices to monitor blood sugar levels if they claim to do so without any skin penetration. The FDA has not evaluated the safety or effectiveness of these devices, and relying on them could lead to inaccurate blood sugar readings. This poses a significant risk for those with diabetes, who need to regularly check their blood sugar levels — typically through a finger prick test or a continuous glucose monitor (CGM) that uses tiny sensors that penetrate the skin and send data to a smartphone app. It's important to note that the FDA's warning pertains specifically to smart rings and watches that promise needle-free monitoring, not to CGMs. If you're concerned about the accuracy of your blood sugar monitor, it’s best to consult your doctor or pharmacist about whether it’s an FDA-approved, reliable device.
