What are the primary data privacy risks associated with continuous glucose monitors for seniors?

✓ Accepted answer

Continuous glucose monitors (CGMs) pose significant data privacy risks for seniors, primarily through the exposure of highly sensitive biometric streams that can be intercepted, mishandled, or misused by third parties in remote care ecosystems. Because these devices transmit real-time physiological data, the attack surface for potential breaches is considerably larger than traditional point-of-care testing.

• Constant biometric stream exposure: CGMs generate data points every 5 to 10 minutes, creating a massive dataset that reveals not just health status but also lifestyle patterns. In the UK, this data is considered 'special category data' under the UK GDPR, requiring strict consent management, while in the US, the Health Insurance Portability and Accountability Act (HIPAA) protections apply only when the device is linked to a covered healthcare provider.
• Third-party app vulnerabilities: Many seniors rely on companion apps to share data with family members or remote monitoring services. These apps often become the weak link; a security flaw in a third-party dashboard can expose the entire medical history. The Federal Trade Commission (FTC) in the US has increased scrutiny on wearable manufacturers for failing to secure data, warning that unencrypted transmission protocols are a primary risk.
• Inferential data risks: Aggregated glucose data can be used to infer broader health conditions, such as kidney function or mental health status. In 2025, regulatory bodies in both jurisdictions began discussing 'inferred data' protections, but as of 2026, most seniors' data remains vulnerable to being sold to insurance companies or used to adjust premiums if the linkage between the device and a insurer is not explicitly severed.
• Insufficient user training: Seniors are often less familiar with digital security hygiene, such as managing multi-factor authentication for health apps. Caregivers should ensure that accounts use strong, unique passwords and that sharing permissions are reviewed quarterly. The UK's Information Commissioner's Office (ICO) and the US's Health and Human Services (HHS) both recommend that providers verify the identity of any recipient of remote data before transmission.
