Your Health, Your Data, Your AI: A Practical Guide to Safer, Smarter Health Care

Health care is changing quickly. Your questions matter.

Artificial intelligence may help write a portal message, flag a scan, estimate a health risk, suggest a clinical trial, or interpret data from a wearable. These tools can support care, but they can also make mistakes, reflect gaps in the data, and make it harder to see who is responsible for an important decision.

Your Health, Your Data, Your AI is a practical, plain-English guide for patients, families, and caregivers who want to understand how health data and AI are shaping care.

Inside, you will learn how to:

• Understand the health data created by your visits, devices, tests, and insurance claims


• Ask better questions when AI influences a recommendation or message


• Recognize the difference between a useful signal and a medical diagnosis


• Protect privacy when data moves beyond a doctor’s office or patient portal


• Understand how bias, weak evidence, and poor oversight can affect care


• Use chatbots and wearables safely


• Prepare for appointments, appeals, caregiver access, and research opportunities

Drawing on real cases, public evidence, and the stories of patients and caregivers navigating a changing system, Jagadeesan “Jag” Mariappan explains what to look for, what to ask, and when to seek a human answer.

You do not need to become a technical expert. You need clear information, practical tools, and the confidence to stay involved in decisions about your care, your data, and the people you love.
