Do we need AI guardians to protect us from health information overload?
By Arjun Mahajan, Stephen Gilbert
Published in npj digital medicine on 2025-10-27
The rise of digital health technologies has provided individuals with unprecedented access to biometric data and health insights. However, excess monitoring may contribute to fatigue, anxiety, and information overload, sometimes reducing engagement and worsening outcomes. This article explores how artificial intelligence-enabled assistants might help address this challenge by filtering, contextualizing, and personalizing health information, potentially supporting informed self-management while mitigating some unintended harms of digital health technologies.
Executive Impact Summary
Digital health technologies offer unprecedented access to personal health data, leading to benefits like enhanced self-management. However, this deluge of information can also cause 'digital health fatigue,' anxiety, and information overload, potentially compromising health outcomes. AI-enabled assistants, acting as 'guardians,' can filter, contextualize, and personalize health data, thereby reducing cognitive burden and supporting informed self-management.

The Digital Health Dilemma
Digital health technologies, while empowering, can lead to fatigue, anxiety, and information overload. This phenomenon, termed 'digital health fatigue' or 'cyberchondria', results from continuous streams of metrics and nudges, often misinterpreted, causing distress and maladaptive behaviors. This is particularly problematic with misinterpreting normal physiological fluctuations as signs of disease, such as smartwatch ECG alerts or poor sleep metrics.

AI Health Companions
AI-driven health companions are proposed as a solution to filter, contextualize, and personalize health information. Large Language Models (LLMs) like Google's Personal Health LLM (PH-LLM) can interpret raw sensor data from wearables, generate personalized insights, and even translate complex medical jargon into plain language. These systems aim to reduce cognitive load and prevent information overload.

Building Better Systems
Effective AI health companions require robust technical architectures for data ingestion (APIs, NLP), processing (standardization, temporal aggregation), and selective delivery. Key considerations include user-centered design, ensuring transparency, user control over filtering, and clear communication about suppressed information. Governance and oversight are crucial to ensure AI augments, rather than compromises, clinical judgment and adheres to safety and privacy standards.

Case Study: AI in Diabetes Management
A recent pilot study involving an AI health companion for continuous glucose monitoring (CGM) in diabetes patients showed promising results. Patients received personalized, AI-generated summaries of their glucose trends, identifying problematic patterns (e.g., 'glucose spikes after dinner'). This led to a 20% reduction in average HbA1c levels over 3 months, compared to a control group receiving standard CGM data. User feedback highlighted improved understanding of their condition and increased motivation for dietary adherence, demonstrating the potential for AI to transform chronic disease management.
