Medical misinformation isn't a new problem. But somewhere along the way, it stopped being background noise and became the loudest voice in the room.

In this episode of How I Doctor, Offcall co-founder Dr. Graham Walker sits down with Dr. Geeta Nayyar a rheumatologist, former Chief Medical Officer at both Salesforce and AT&T, and bestselling author of Dead Wrong. Together they diagnose how medical misinformation went from the fringes of the bell curve to the halls of power, and what physicians can actually do about it.

Geeta doesn't come to this conversation as a distant observer. She's spent her career at the intersection of clinical medicine and health tech, advising organizations from the AMA to Fortune 500 companies on how to navigate a healthcare information landscape that has fundamentally broken down.

Her perspective is grounded in something personal too. She saved her own mother's life during fellowship by doing what the system failed to do: gathering all the data, laying it out on the floor, and refusing to accept a diagnosis that didn't add up. That experience drove her into rheumatology and eventually into health tech, motivated by a simple question she still hasn't stopped asking: what does the average patient do when they don't have a doctor in the family?

That question has never been more urgent. When patients can't get an appointment for six to nine months, they don't wait. They go to TikTok. They follow influencers who are confident, simple, and wrong. And while wellness gurus monetize confusion, hospitals are still telling their physicians they can't mention their institution on social media. Medicine left a vacuum, and the wrong people filled it.

This episode is a call to action for every physician who has watched that happen and felt powerless to stop it. Graham and Dr. G make the case that physicians aren't just allowed to take the microphone. They are obligated to! And that the hospitals and health systems who figure that out first won't just be doing the right thing. They'll be winning.
