The US Food and Drug Administration (FDA) has urged users not to measure their blood sugar levels using smart watches and rings. Such devices use algorithmic calculations that are far removed from what medical equipment displays, says on the agency’s website.
The FDA emphasized that noninvasive devices should not be confused with continuous glucose monitoring (CGM) devices, which are approved by the FDA and can sync with smartwatches through special apps. CGMs use a small sensor placed under the skin and measures glucose levels in the interstitial fluid.
According to the manufacturers of such “smart” watches and rings, these devices can measure blood sugar levels using optical or electrical signals. But the FDA warns that such devices can give inaccurate or inconsistent results. This can cause diabetics to receive the wrong amount of insulin or other medications, which can cause hypoglycemia or hyperglycemia.
An American company is said to be producing a watch that will use laser spectroscopy to analyze blood. Samsung is also exploring the possibility of using an optical sensor to measure blood sugar. In 2023, Huawei released the Huawei Watch 4 smartwatch, which has a noninvasive glucose measurement function but only works in the Chinese market.
