Careful territory.
WHAT IT CAN SAFELY DO
Explain a condition in plain language Explain what a test or procedure involves Help you prepare questions for an appointment Explain terminology in a letter or report
WHAT IT MUST NOT DO
Diagnose Recommend treatment Advise on medication Tell you whether to seek care
WHY
It does not know you, cannot examine you, and produces confident wrong answers.
Health is where a confidently wrong answer causes the most harm.
THE PREPARATION USE
"I have an appointment about [condition]. What questions should I ask?"
Genuinely valuable. Most people forget what they meant to ask.
FOR UNDERSTANDING WHAT YOU WERE TOLD
"My doctor said [what]. What does that mean?"
Useful, and check with the clinician.
WHAT NEVER TO DO
Delay seeking care because a model reassured you Change medication on generated advice Self-diagnose
IF YOU ARE WORRIED ABOUT SOMETHING
See a qualified person. That is not a small inconvenience compared with being wrong.
