How People Are Using AI For Medical Advice

In 2025, patients upload scans and histories to ChatGPT, ask o3 and Grok for differentials and test suggestions, and bring the outputs to their physicians for review. Posts describe corrected diagnoses, treatment changes, and doctor-approved next steps; clinicians also trial MAI-DxO and MedGemma on open-ended cases and multimodal records within a review workflow.

ChatGPT baby. Katherine Boyle (@KTmBoyle) uploads every diagnostic and blood test to AI before sharing with her doctors. They think it’s cool. It shows how a new generation approaches healthcare with AI at their side. “We’re just living in this completely different reality.” https://t.co/u6l9WpNZ6P

yesterday a patient told me she used snapchat’s AI to interpret her fetal ultrasound makes me wonder where patient–consumer trust accrues in AI-first medicine, and what actually feels like “medicine” from the patient perspective consumer medical AI might be big tech’s best shot at breaking into healthcare after years of trying

Current state of the medical establishment: Brought a friend to the ER for a high fever. Put their symptoms into Grok. Grok told me to ask for 4 tests. Doctor said 1 of them is unnecessary. I insisted we do them all. Test came back positive on the one he didn’t want to do.

this story is going wildy viral on reddit. ChatGPT flagged a hidden gene defect that doctors missed for a decade. ChatGPT ingested the patient’s MRI, CT, broad lab panels and years of unexplained symptoms. It noticed that normal serum B12 clashed with nerve pain and fatigue, hinting at a methylation block. Within months tingling eased and brain fog cleared. The primary physician reviewed the genetics report and agreed the variant unified the entire case. IMO, time has already come, taking a 2nd opinion from the best healthcare-AI model should be made part of medical code of practice. ------ reddit. com/r/ChatGPT/comments/1lrmom4/chatgpt_solved_a_10_year_problem_no_doctors_could/

I wanted to publicly thank @sama and @aidan_mclau I don’t know how to show my gratitude, so I figured a post to let you know how much helpful you’ve been wouldn’t hurt. Thanks to you, I got 2 months of ChatGPT Pro to use Deep Research for my rare disease, and in that time I’ve learned things even my cardiologists couldn’t tell me, it has improved my life a lot. Now I’m back on the Plus plan (I've been a Plus user since it came out and I'll always be, the value is insane for the price), which luckily includes 10 Deep Research uses per month, that should be enough. You’re saving lives, and I’ll always be grateful for what you’ve done for me. I’ve never seen a CEO as kind and approachable as Sam, or someone at a big company as committed to helping humanity as Aidan. Thank you both so much. OpenAI is changing lives thanks to you and everyone behind the scenes. ❤️ By the way, Sam, if you happen to read this: happy early birthday for Tuesday! :)

ChatGPT literally saved me. Last night I wasn’t feeling great, nothing dramatic just a bit off. I Ignored it and went to bed Woke up with stronger pain but stayed calm Out of curiosity I typed my symptoms into ChatGPT It said: “Go to the hospital. NOW” Kinda dramatic I thought I’ve asked it about symptoms before and it never said anything like that, so I listened Meanwhile the pain kept getting worse Won’t go into details but doctors said if I had arrived 30 mins later I would’ve lost an organ So yeah AI literally saved me Thanks @OpenAI I guess

I’m absolutely blown away by @OpenAI’s new o3 model! I’ve had early access and haven’t put it down for days. This release feels like the milestone we experienced with o1-preview and o1-pro, but smarter and more reliable in every way, it truly cranks everything up to eleven! In fact, I feel o3’s intelligence is at or near genius level! It never hallucinates, and its new agent-style tools effortlessly handle multi-step tasks with incredible reasoning and precision, generating complex incredibly insightful and based scientific hypotheses on demand! When I throw challenging clinical or medical questions at o3, its responses sound like they’re coming directly from a top subspecialist physicians: precise, thorough, confidently evidence-based, and remarkably professional, exactly what you’d expect from a genuine expert on the topic. I feel it is also clearly superior to the current SOTA model Gemini 2.5-pro in these aspects, and more intelligent. Without reservation, I confidently claim this is a total game-changer for science, medicine, and likely many other fields! Kudos to the entire amazing team at OpenAI, there’s no doubt this advance will continue pushing humanity forward and significantly improve our lives! 👏👏👏

My friend went to the doctor recently. Doctor diagnosed them with a serious issue. Friend took the medical scans and uploaded to ChatGPT. ChatGPT diagnosed friend with something different and much lower risk. Friend sends ChatGPT results to doctor. Doctor confirms they made a mistake and ChatGPT is right. Insane situation. But obvious where the world is quickly going…
