Members strongly cautioned against using smartwatches claiming to monitor blood glucose, with the consensus being that these devices, particularly those from China, are dangerously inaccurate and should never be used for treatment decisions by people with diabetes. Several members shared firsthand testing experiences showing wildly inconsistent readings that could vary by several points within minutes, with one member noting their watch showed numbers from 2.7 to 8.8 mmol/L when their actual range was much tighter. A recurring theme was that while other features like pulse rate and oxygen levels may be accurate, the glucose monitoring technology has not received approval in any country, remains years away from being reliable, and could put lives at risk if relied upon instead of proven methods like fingersticks or CGMs.
