ChatGPT has made a material difference in my ability to understand health problems, test results, and to communicate with doctors effectively. My wife and I were talking last night about how helpful it was in 2025. I hope that it continues to be good at this.

I want regulators to keep an eye on this and make smart laws. I don't want it to go away, as its value is massive in my life.

(One example, if you are curious: I've been doing rehab for a back injury for about 10 years. I worked with a certified trainer/rehab professional for many years and built a program to keep me as pain-free as possible. I rebuilt the entire thing with ChatGPT/Gemini about 6 weeks ago, and I've had less pain than at any other point in my life. I spent at least 12 hours working with AI to test and research every exercise, and I've got some knowledge to help guide me, but I was amazed by how far it has come in 12 months. I ran the results by a trainer to double-check it was well thought out.)

This sounds like excellent evidentiary material for a future insurer or government health provider to decide you're uninsurable, not eligible for a job, and so on.

And the great thing about it is that you already signed all your rights away for them to do this exact thing, when we could have had an open world with open models run locally instead where you got to keep your private health information private.

  • Can you explain the exact way in which this is possible? It’s not legal to be denied jobs based on health. Not to deny insurance

    • And how would you know what they base their hiring upon? You would just get a generic automated response..

      You would not be privy to their internal processes, and thusfar not be able to prove wrong doing. You would just have to hope for a new Snowden and that the found wrongdoings would actually be punished this time.

      There is a vast gap between what is not legal and what is actually actionable in a court of law, which is well known to a large power nexus.

    • > It’s not legal to be denied jobs based on health. Not to deny insurance

      The US has been pretty much a free-for-all for surveillance and abusing all sorts of information, even when illegal to do so. On the rare occasions that they get caught, the penalty is almost always a handslap, and they know it.

    • How are you ever going to prove this?

      You just get an automated denial from the ATS that's based on the output from AI inference engine.

    • The ADA made it illegal to discriminate against job seekers for health conditions and ObamaCare made it illegal to base cover and rates on pre-existing conditions.

      What are the chances those bills last long in the current administration and supreme court?

  • These strawman arguments lack nuance.

    If the person can use AI to lead a noticeably better life, something that may have been impossible previously due to economic circumstance, then the first order benefits outweigh the second order drawbacks.

    I’m not disputing what you’re saying, I just think that treating it like a zero sum game every time the conversation comes up is showing an immense amount of privilege.

    You, me, the parent commenter; we’re all dying, we don’t have time to optimise for the best outcome.

    • If the tool that allows you to have a “noticeably better life” is heavily subsidized by venture capital, you have turned yourself into a ticking bomb.

    • there is also no easy way to build a perfect health AI without giving up some privacy. Now there will always be risks, but this is why I think China might overtake everyone else in Healthcare AI at the least

  • > when we could have had an open world with open models run locally instead where you got to keep your private health information private

    But we can have that? If you have powerful enough hardware you can do it, right now. At very least until the anti-AI people get their way and either make the models' creators liable for what the models say or get rid of the "training is fair use" thing everyone depends on, in which case, sure, you'll have to kiss legal open-weight models goodbye.

  • What do you consider the purpose of life to be? To me being in good health is immensely more important than health insurance, a government health plan, or a job.

    I know that neither health insurers nor any government agency nor anybody else have even 0,0000000000000001% as much interest in my health, well being and survival as I do.

    When it is the matter of my health and my life, I care as much about what an insurer or employer thinks as I would care about what the Ayatollah of Iran thinks. Or what you think. Ie: Those opinions are without any value at all.

    • Most of us cannot afford to pay the full cost of healthcare for an emergency or major intervention. Medical bankruptcy is an increasingly common phenomenon.

      So if insurers can cut you off based on your ChatGPT queries or test results then you may find yourself in serious debt, homeless, without medical care, etc

  • If an insurer is able to reduce (or recoup) costs from likelier risks, then the remaining insureds benefit from lower premiums.

    If the goal is providing subsidies (i.e. wealth transfers), then insurance is not the way to do it. That is the government’s role.

    • Insurance that is maximally responsive to patient health changes in terms of cost (ie making healthier people pay less) ends up being an inefficient way of just having people pay for their healthcare directly.

      And it naturally means the people with highest premiums are the least likely to be able to afford it (the elderly, the disabled, those with chronic conditions that make them less likely to maintain high earning jobs steadily, etc)

    • Not a US citizen, so a genuine question: do US health insurance companies have a track record of passing on such savings to consumers?

      That has not been my impression as an outside observer.

      17 replies →

    • We agree that insurance is not the right way to handle health as a product, since some people predictably need much more medical treatment than others. But it’s how the US has chosen to do it, so we have to do it in a way that works. Correctly identifying a systemic issue won’t pay your medical bills.

I've had a similar positive experience and I'm really surprised at the cynicism here. You have a system that is good at reading tons of literature and synthesizing it, which then applies basic logic. What exactly do the cynics think that doctors do?

I don't use LLMs as the final say, but I do find them pretty useful as a positive filter / quick gut check.

  • This is the crux of the argument from the article.

    > get to know your members even before the first claim

    Basically selling your data to maximise profits from you and ensure companies don't take on a burden.

    You are also not protected by HIPAA using ChatGPT.

    • I'm in Europe btw, but yes I hope Americans get protection soon. I expect the backlash if that were to happen is enough to trigger legislative action.

  • Because we've all used LLMs.

    The make stuff up. Doctors do not make stuff up.

    They agree with you. Almost all the time. If you ask an AI whether you have in fact been infected by a werewolf bite, they're going to try and find a way to say yes.

    • Doctors make stuff up all the time; they might deeply believe they are not, but they are detectives trying to figure out what is going on in a complex system.

      AI is a tool that can be useful in this process.

      Also, our current medical science is primitive. We are learning amazing things every year and the best thing I ever did was start vetting my doctors to try to find those that say "we don't know" because it is a LOT of the time.

    • If the person is telling you "I had a problem, did what the LLM said, it worked", does that not work a new evidence for you? Is it not possible that someone has had a different experience from you? Is it not possible that they're good to different degrees in different domains?

      I just asked chatgpt:

      > I have the following information on a user. What's his email?

      > user: mattmanser

      > created: March 12, 2009

      > karma: 17939

      > about: Contact me @ my username at gmail.com

      Chatgpt's answer:

      > Based on the information you provided, the user's email would be:

      > mattmanser@gmail.com

      Does this serve as evidence that some times LLMs get it right?

      I think that your model of curent tech is as out of date as your profile.

I also think health (and car-problem diagnosis) are excellent tasks for LLMs.

The you-are-the-product thing, and privacy, has me wondering when Apple will step in and provide LLM health in a way we can trust.

I know I say that and I face the slings and arrows of those distrusting Apple, but I still believe they're the one big company out there that knows that there is money in being the one guy that doesn't sell your data.

I don't think one can deny the benefits here. The detractors here are like don't build a side walk coz someone may trip and fall or don't plant trees in your front yard coz of what happened to the Texas governor.

Most would likely agree that everything needs a balanced approach, bashing a service completely as evil and fully advocating people to stay away vs claiming the service is flawless (which the OP isn't doing btw) aren't either a balanced position.

Think different doesn't have to mean think extreme.

On the other hand, sometimes you end up like this guy. Are you feeling lucky?

  • You could also list plenty of horror stories where people went to medical professionals and got screwed over. There is this myth that people can go to doctors and get perfect attention and treatment. Reality is far from that

    • There’s the concept of “personal advocacy” when receiving healthcare. Unfortunately, you’ll only get the best outcomes if you continually seek out treatment with diligence and patience.

      But framing it as a “myth [of] perfect attention and treatment” sounds a bit like delegitimizing the entire healthcare industry in a way that makes me raise my eyebrow.

    • A big part of the legal implications of LLMs and AI in general is about accountability.

      If you are treated by a human being and it goes sideways, you could sue them and/or the hospital. Now, granted, you may not always win, it may take some time, but there is some chance.

      If you are "treated" by an LLM and it goes sideways, good luck trying to sue OpenAI or whoever is running the model. It's not a coincidence that LLM providers are trying to put disclaimers and/or claims in their ToS that LLM advice is not necessarily good.

      Same goes for privacy. Doctors and hospital are regulated in a way that you have a reasonable, often very strong, expectation of privacy. Consider doctor-patient confidentiality, for example. This doesn't mean that there is no leak, but you can hold someone accountable. If you send your medical data to ChatGPT and there is a leak, are you going to sue OpenAI?

      The answer in both cases is, yes, you should probably be able to sue an LLM provider. But because LLM providers have a lot of money (way more than any hospital!), are usually global (jurisdiction could be challenging) and, often, they say themselves that LLM advice is not necessarily good (which doctors cannot say that easily), you may find that way more challenging than suing a doctor or a hospital.

  • "…a 60-year-old man who had a “history of studying nutrition in college” decided to try a health experiment: He would eliminate all chlorine from his diet…"

    You can see already that this can easily go sideways. This guy is already exploring the nether regions of self-medication.

    It would be ideal if LLMs recognized this and would not happily offer up bromine as a substitute for chlorine, but I suspect this guy would have greedily looked for other shady advice if LLMs had never existed.

  • No, there's a difference between radically changing your diet and changing up your stretch/strength routine.. you don't just "end up" like one of them, you can evaluate that the downside risk of the latter is much lower and try it safely while recognizing that an extreme diet might not be so safe to try without any professional guidance.

  • You have to use your head, just like online forums or with doctors :)

    I've had doctors tell me to do insane things. Some that caused lasting damage. Better to come with a trust-but-verify attitude to humans and AI.

  • The man in the article did not use it as a research help and did not verify it with experts.

    So what's your argument?

  • Did he also drive into a lake following Google Maps' driving directions?

It seems like outcomes are probably K-shaped: those who are capable of critical thinking and deciding what type of information should be confirmed by a healthcare professional and what type of information is relatively riskless to consume from ChatGPT should have positive outcomes.

Those who are prone to disinformation and misinterpretation may experience some very negative health outcomes.

If you'd been doing the rehab for 10 years, what did you need exactly? It seems like you should have had a decade to ask whatever questions you wanted.

  • That was a specific example where AI helped me revamp my workout. No workout stays static; it has evolved over the years, in small ways. With this change I threw out 60% of it, and replaced it with a lot of work to make sure I was working full body and taking into account the injury. I was having more pain in 2025 and was only pain-free around 90% of the time. I wanted to get stronger but also revet everything I was doing to hopefully get out of that pain.

    Hope that helps!

    You can ask a trainer questions, they are super helpful and taught a lot, but it is still one person, and they don't often sit around at night reading university/research papers on the injury, etc.

Or it's a placebo effect.

And if it didn't work out and made you worse or, god forbid, the advice caused you to get seriously injured, then what? ChatGPT won't take any responsibility.

I have so many issues with our current health system but an alternative is not an unreliable search tool that takes no responsibility for the information it provides.

  • > And if it didn't work out and made you worse or, god forbid, the advice caused you to get seriously injured, then what? ChatGPT won't take any responsibility.

    Realistically in 99% of actual cases where this happens due to human medical advice, the humans too won't take any responsibility.

  • You always have to use critical thinking, listen to your body, and get advice from trainers in the trenches. As I mentioned, I did all of those things :)

  • on a similar vein, I have recurring back issues due to a spinal issue. I gave the issue to ChatGpT and it gave me almost all of the exercise I had been given years ago by a chiropractor. It's nowhere near a replacement for having someone coach me through movements though.

It can be helpful, but also untrustworthy.

My mother-in-law has been struggling with some health challenges the past couple of months. My wife (her daughter) works in the medical field and has been a great advocate for her mother. This whole time I've also been peppering ChatGPT with questions, and in turn I discuss matters with my wife based on this.

I think it was generally correct in a lot of its assertions, but as time goes on and the situation does it improve, I occasionally revisit my chat and update it with the latest results and findings, and it keeps insisting we're at a turning point and this is exactly what we should expect to be happening.

6 weeks ago, I think its advice was generally spot on, but today it's just sounding more tone-deaf and optimistic. I'd hate to be _relying_ on this as my only source of advice and information.

  • Totally agree, it can be a bit of an echo chamber. I had an infection post-dental-work. Bing Chat insisted I had swollen lymph nodes from a cold that would resolve on their own, then decided I had a salivary gland infection. After a follow-up with a real-world ENT, it was (probably accurately) diagnosed as a soft-tissue infection that had completely resolved on two rounds of antibiotics. The AI never raised that possibility, whereas the ENT and dentist examined me and reached that conclusion immediately.

    I do think AI is great for discussing some health things (like "how should I interpret this report or test result?"), but it's too echo chamber-y and suggestion-prone for accurate diagnosis right now.

    • Ya I wouldn't trust it for diagnosis at this point. But it can help you get pointed in the right direction so human, tests, and the scientific process can try to figure out the rest.

      Doctors struggle with diagnosis as well. I have stories and I bet everyone has stories about being passed from doctor to doctor to doctor, and none of them talk to each other or work holistically.

That's awesome that it's helped you so much, chronic back pain is awful. Is it possible though, that this could be interpreted as a failure of the trainer to come up with a successful treatment plan for you? "Sudden" relief after 10 years of therapy just because you changed the program seems like they were just having you perform the wrong exercises no?

  • We have to also understand that the trainer didn't get to spend 12 hours of researching every minutia or do a trial and error study to get to where OP got to. This doesn't necessarily mean the trainer failed, just that they were constrained by time, which OP wasn't. And I think that is the essence of this tech, when used wisely, I can lead to results like these which you can't get despite having access to the best talent for a limited time. Only the well afforded can afford a full time trainer/therapist.

    • Absolutely, I didn't mean any disrespect towards any of the professionals helping OP with their back issues. It can be an incredibly hard thing to treat.

  • The trainer was a godsend, got me to ~95% pain-free, and taught me all kinds of things. He is amazing.

    But 2025 was maybe down to 90% pain-free, and I want to get stronger. So I did a big rewrite of my entire workout plan and checked everything. AI wasn't perfect, but it was amazing when you already know some.

    It is still a tool I had to direct, and it took a few days of work. But I'm amazed at where it got me to. It took the injury into consideration and my main sport, and built around that. In the past I tried do this online and couldn't do it given the numerous factors involved. It was not perfect, but over the course of a few days, I was able to sort it out (and test with a trainer on the approach a few weeks after).

    I've been 100% pain free for 6 weeks in a way I haven't felt in a long time.

    • Without getting into your specific injury or sport, what was the biggest change compared to the trainer’s program?

      Was it something unexpected like "exercise this seemingly unrelated muscle group that has nothing do with your injury but just happens to reduce pain by 75% for some inexplicable reason"?

      Or was it something more mundane like "instead of exercising this muscle every day, do it every other day to give it time to rest"?

> to communicate with doctors effectively

Did the doctors agree? I never thought of AI as a good patient navigator, but maybe that’s its proper role in healthcare.

  • Like anything, it is a tool; someone using WebMD badly, and someone can use it well.

    I have found it helpful as I can ask ChatGPT questions, teach myself about what I am dealing with, and understand it better so I can ask my doctor questions. I still verify a lot, I still read articles on verified medical sites, etc., but it helps me do that a lot quicker, and I seem to learn quicker.

    I'm sure someone can also go deep into anxiety with it as well if they approach it that way. It isn't a miracle button, but it is an AMAZING tool IME.

I agree. LLMs cannot and should not replace professionals but there are huge gaps that can be filled by intro provided and the fact that you can dig deeper into any subject is huge.

This is probably a field that MistralAI could use privacy and GDPR as leverage to build LLMs around that.

  • One of the big issues I have with LLMs that when you start a prompting session with an easy question it all goes great. It bring up points you might not have considered and appears very knowledgeable. Fact checking at this stage will show the LLM is invariably correct.

    Then you start "digging deeper" on a specific sub-topic, and this is where the risk of an incorrect response grows. But it is easy to continue with the assumption the text you are getting is accurate.

    This has happened so many times with the computing/programming related topics i usually prompt about, there is no way I would trust a response from an LLM on health related issues I am not already very familiar with.

    Given that the LLM will give incorrect information (after lulling people with a false sense of it being accurate), who is going to be responsible for the person that makes themselves worse off by doing self diagnosis, even with a privacy focused service?

    • That's a good point—and I have probably fallen victim to it as well: the "sliding scale" of an LLM's authority.

      Like you, I fact-check it (well, search the internet to see if others validate the claims/points) but I don't do so with every response.

    • The responsibility falls always to the patient. That’s true with doctors are as well: you visit two doctors they give you different diagnosis, one tells to go for surgery, the other tells you it’s not worth the hassle. Who can decide? The patient does.

      LLMs are yet another powerful tool under our belt, you know it’s hallucinating so be careful. That said, even asking specialized info about this or that medical topic can be a great thing for patients. That’s why I believe it’s a good thing to have specialized LLMs that can tailor responses on individual health situations.

      The problem is the framework and the implementation end goal. IMO state owned health data is a goldmine for any social welfare system and now with AI they can make use of it in novel ways.

It doesn’t even have to be that well-read (although it is),

it just has to listen to your feedback more than 11 minutes per visit,

so it can have a chance at effectively steering you…

  • I'm lucky to live in Europe now, I cried the first time I went to a doctor here, he chatted with me for 45 minutes. I begged my doctor in the USA to let me book back-to-back sessions, so I could ask him questions and better understand what was going on. He said no; I only had 10 minutes, and he generally didn't have time to answer any questions or provide details. He was a good doc, but just couldn't take the time, and insurance wouldn't comp him for back to back appointments.

    • > He was a good doc, but just couldn't take the time

      Sure he could.

      He would just be paid less,

      and you can’t have that - doctors are very important people!

This kind of comment scares me because it's an example of people substituring professional advice for an LLM where LLMs are known to hallucinate or otherwise simply make stuff up. I see this all the time when I write queries and get the annoying Gemini AI snippet on a subject I know about and often I'll see the AI make provably and objectively false statements.

  • You have to use critical thinking + it helps to have some info on the subject + it shouldn't be used to perform self-surgery :)

    I spent about 12 hours over 2 days, checking, rechecking, and building out a plan. Then I did 2-hour sessions on YouTube, over several weeks, learning the new exercises with proper form (and that continues as form is hard). Followed by an appointment with a trainer to test my form and review the workout as a hole (which he approved of). No trainer really knows how this injury will manifest, so a lot is also helped because I have 10 years of exp.

    This isn't a button click, and now follow the LLM lemming. This is a tool like Google search but better.

    I could not have done this before using the web. I would have had to read books and research papers, then try to understand which exercises didn't target x muscle groups heavily, etc. I just couldn't do that. The best case would have been a trainer with the same injury, maybe.

  • You are exaggerating. LLMs simply don’t hallucinate all that often, especially ChatGPT.

    I really hate comments such as yours because anyone who has used ChatGPT in these contexts would know that it is pretty accurate and safe. People also can generally be trusted to identify good from bad advice. They are smart like that.

    We should be encouraging thoughtful ChatGPT use instead of showing fake concern at each opportunity.

    Your comment and many others just try to signal pessimism as a virtue and has very less bearing on reality.

    • All we can do is share anecdotes here, but I have found ChatGPT to be confidently incorrect about important details in nearly every question I ask about a complex topic.

      Legal questions, question about AWS services, products I want to buy, the history a specific field, so many things.

      It gives answers that do a really good job of simulating what a person who knows the topic would say. But details are wrong everywhere, often in ways that completely change the relevant conclusion.

    • LLM give false information often. The ability for you to catch incorrect facts is limited by your knowledge and ability and desire to do independent research.

      LLMs are accurate with everything you don't know but are factually incorrect with things you are an expert in is a common comment for a reason.

  • I have this same reaction.

    But I also have to honestly ask myself “aren’t humans also prone to make stuff up” when they feel they need to have an answer, but don’t really?

    And yet despite admitting that humans hallucinate and make failures too, I remain uncomfortable with ultimate trust in LLMs.

    Perhaps, while LLMs simulate authority well, there is an uncanny valley effect in trusting them, because some of the other aspect of interacting with an authority person are “off”.

>my ability to understand health problems

How do you know that this understanding is correct? To me, epistemologically, this is not too different from gaining your health knowledge from a homeopath or gaining your physics knowledge from a Flat Earther. You are in no position to discern the validity of your "knowledge".

  • It isn't a 0 or a 1; it is a spectrum. Doctors don't understand everything, either, which is the scary thing we don't like to realize.

    What it specifically helps me to understand are things like: probable outcomes, symptoms in greater detail, as well as how they manifest in patient populations, explains it as if I was a 10/15/20 year old in detail to help me understand the basics of what might be going on, similar things in possible pharma options, general response treatments and pros/cons, etc.

    I'm not using this to perform self-surgery or build a belief system :), I'm just trying to learn and understand what is going on at a better level.

    Hope that helps :)

    • >It isn't a 0 or a 1; it is a spectrum. Doctors don't understand everything, either,

      It's not equivalent. Doctors are aware of the limits of their knowledge and the error bars around their knowledge. You and an LLM don't. There is no comparison here. It's like trying to compare a random person lost in a person versus someone lost in a forest who is used to it.

      Even with an LLM, you still have to be able to ask the right questions and be able to push back where necessary. I don't think most people are able to do this especially when some of the responses which might be right are counterintuitive to them and some of the dodgy responses might seem more aligned to their worldviews.

      If you want to learn, it is fine (knowing that there is a context there you likely are missing) but performing actions based on knowledge you don't have context of is dangerous. It applies to vibe coding as much as it does to your personal health. This is how you end up injecting yourself with blood from younger people believing it will make you immortal.

  • It's a lot easier to double-check, cross-reference, or test the validity of advice given by a gpt. It has no authority, no persuasion mechanisms, and its opinions are there in plain text ready to be picked apart. You can ask it for references and non-confrontationally challenge it on the things you're sceptical about. It generally avoids woo in my experience though it's hardly always correct in specific advice, it can definitely point you in productive directions. Which is completely different from discussing anything health with a homeopath, who at best will try to get you to avoid productive treatment and at worst poison you.

  • > You are in no position to discern the validity of your "knowledge".

    He is the only one who is in that position, because he is the only person who is inside his body. He is physically and mentally a hundred percent in the position to discern the validity of the advice.

Anything you say can and will be used against you.

  • I've been on the web since it was born. When will this happen? :)

    How is this manifesting in reality?

  • You bring up an interesting point.

    How is it we have come to a place in society where we second-guess everything we type? But perhaps also where we go (with our "tracking devices" in our pockets…).

    I mean, obviously the internet is what changed everything. But it is like you have a megaphone strapped to your face whenever you connect to a site and make a comment.

    Maybe this is not a good thing.

Sounds like you’re a good little product… abundant potential for shareholder value to be extracted from you and others like you. A trip to the library or a consult with a professional would’ve given you the same or better results.
