Watches That Claim to Measure Glucose Are a Scam
In recent years, various smartwatches and wearable devices have hit the market, claiming to measure blood glucose levels without piercing the skin. These claims have generated excitement, particularly among people with diabetes who must regularly monitor their glucose. However, the reality is simple: these watches do not work, and they never have despite being available from major retailers as well as online market places.
No Scientific Basis
Currently, the only medically accurate way to measure blood glucose involves piercing the skin, either with a finger prick or a continuous glucose monitor (CGM) that uses a small sensor wire under the skin (held in place by an adhesive patch). Non-invasive glucose monitoring has been a long-standing goal of medical science, but no company has successfully developed a reliable and accurate device.
The Manufacturers Know the Claims are Misleading
Despite their marketing hype, the manufacturers of these so-called “non-invasive glucose monitors” are aware that their products do not provide accurate glucose readings. They may describe the readings as glucose trends rather than results or in some cases, they include disclaimers in fine print, stating that the device is “not for medical use” or “for wellness purposes only.” This allows them to continue selling these misleading devices without having to meet the rigorous standards required for medical equipment.
Since the 1990s, companies have been promoting the idea that blood glucose can be measured through the skin using light beams. In 1996, the U.S. Securities and Exchange Commission (SEC) charged Futrex and its director, Rosenthal, with fraud for falsely claiming that their hand-held "Dream Beam" analyzer could measure and accurately predict a person's blood glucose level by passing infrared light through a finger. However, neither the Dream Beam nor any other infrared blood glucose analyzer tested by Futrex was ever capable of producing accurate results. https://www.sec.gov/files/litigation/litreleases/lr15061.txt
No Regulatory Approval
To date, no reputable medical regulatory body, such as the FDA (USA), EMA (Europe), or TGA (Australia), has approved a non-invasive glucose monitoring watch. If such technology existed and were effective, it would revolutionize diabetes care and be widely endorsed by medical professionals.
Dangerous for People with Diabetes
The most concerning aspect of this fraud is the potential to cause serious harm. People with diabetes rely on accurate glucose readings to make critical decisions about insulin use, diet, and medication. A fake device that produces fictitious readings can lead to serious health risks, including hypoglycemia, hyperglycemia, diabetic ketoacidosis and if operating a vehicle or heavy equipment others can be endangered.
The Bottom Line
If a product claims to measure blood glucose without piercing the skin, it is a scam. There is currently no scientifically validated technology that can achieve this. The only safe and effective way to monitor glucose levels remains through traditional blood-based methods. Until reputable medical institutions confirm otherwise, avoid these fraudulent products and warn others to do the same.
If you're looking for reliable glucose monitoring, stick with established and medically approved devices. Don't fall for the false promises of smartwatch scams—your health is too important.
