The Brazilian National Health Surveillance Agency (ANVISA) issued a resolution on September 2, 2025, prohibiting the marketing and any form of circulation of a set of devices advertised as glucose meters.

These were rings that, without the need for punctures, claimed to measure glucose, blood oxygen, and heart rate.

The decision was based on the fact that these products lack health registration and lack scientific evidence to support their effectiveness.

WHOM DOES IT IMPACT?

The direct impact is on patients with diabetes, consumers in general, manufacturers and importers, regulatory agencies, and the healthcare system.

CONCLUSION:

The ANVISA ban has a significant impact on the protection of diabetic patients and the fight against misleading health advertising. The measure sends a clear message, medical devices must be registered and have scientific evidence before reaching consumers.
