Ahh, AI is coming for your job. Full sarcasm, is there one that’s that’s more immune?

cough Immunology

I mean, probably not. No expert, but everytime I go to an immunology meeting (I'm a paediatrician) they've got a whole stack of new diseases. The field is moving fast, and there has to be a careful amount of shared decision making about when to test, what a positive test means and so on. I reckon they're as safe as any of us.

There’s more than two options here. It was already difficult to deal with self diagnosis for doctors, now we have a machine that outputs recommendations, and does it with confidence whether it’s correct or not. The same issues that were present with search-engine self diagnosis are still present with LLMs. If you provide Google with an incomplete list of symptoms and can’t interpret the information you find correctly…

There are quite a few disclaimers everywhere that soften confidence: "always ask a medical specialist", "I'm not a doctor", "this could have been this or that but really not sure", etc.

No one cares about this, especially those who believe the machine. It's just there for the provider to avoid responsibility.

Went to a new dentist recently and his staff took x-rays of my teeth. I was then waiting for him to come speak with me about what the x-rays show him yet i just took a pic and uploaded it to Gemini. 9 months back my previous dentist said i should have a filling or potentially a crown was needed. I told Gemini this and that ive only about 3 fleeting pain issues in that area. With the x-ray and that info Gemini told me the exact same thing the dentist later came in and told me. If pain comes back and for long periods of time then there's an issue as the x-rays look fine.

Overall i see a great opportunity for x-ray techs (radiographers even when Jensen from NVidia says the first field he recommends not getting into - Radiology which is the step above) to open their own businesses for people who want to use AI for self care and help. Have one doctor or dentist on staff to use as needed.

I'm a radiologist but can't really weigh in without seeing the full 3D MRI dataset. Regarding this point: > They performed shockwave therapy on my shoulder even though a recent clinical practice guideline says clinicians should not use or recommend shockwave therapy for rotator-cuff tendinopathy without calcification; I was told during ultrasound that there was no calcification. Ultrasound isn't a great way to assess…

Agreed. Not a radiologist, but I do a fair bit of MRI research. Experts vs lay people probably have different success with getting the right diangosis out of a frontier model. Subtle changes in prompts can cause different diagnosis[1]

I've seen a lot of friends and family members almost immediately get offered surgery for shoulder pain. It's just often the default for people that do surgeries for a living. I also had a pretty painful shoulder issue at one point, where the pain just wasn't subsiding for months. I tried massages and acupuncture as I didn't want to do surgery, but it wasn't helping at all. The thing that fixed it for me was just real…

I had issues with my shoulder for years. Tried PT as well as pull/push-ups but doing that made the pain worse (if I wasn't doing any exercises involving the shoulder it was "fine")…

Everyone talking about how doctors know better or have some context that is not shown here. But are you all forgetting that they literally injected a homeopathic drug on the author? Between that and Claude sometimes hallucinating, it’s probably worth encouraging patients to take second opinion always.

> But are you all forgetting that they literally injected a homeopathic drug on the author?

I'm no fan of pseudoscience either, but this is where things get blurry. The placebo effect is real even if patients are aware of it. If you give a patient a homeopathic drug while informing them of potential side effects (if any), and then they feel better, have you hurt them? Or have you helped them?

I personally have no interest in trying homeopathic medicines, but the reality is that many patients do take these and are adamant they help. As long as any risks are communicated and there are no serious side effects, it's difficult to make an argument against their use in patients who report a subjective benefit.

That might be doctors new nightmare: people who second guess everything with AI. Previously it was "google your symptoms".

The NYT did this profile a while back: "Ben Riley was already writing about the risks of chatbots when his dad started trusting A.I. over his doctor." The dad was a retired neuroscientist who delayed cancer treatment against medical advice because he was certain he had been misdiagnosed based on his own research that he did with the help of A.I. https://www.nytimes.com/2026/04/13/well/ai-chatbots-cancer.h... There's…

i mean, other smart people have famously delayed cancer treatment without needing poor guidance from LLMs! that's not at all new or unique to LLM chatbots

So Opus might be correct?

~2 years ago I used ChatGPT "deep research" to investigate a chronic sinus infection I'd been fighting for ~3 years. After seeing 3 GPs and 3 visits with an ENT, I fed all the observations I had into the AI. In particular, I couldn't get the ENT to explain why he visually saw, via a scope, evidence of allergic reaction in my sinuses, but then later concluded, after an allergy test, that it couldn't be treated via all…

Daily allergy tablets are associated with huge increases in early onset Alzheimer’s. Glad you found something that works, but might be good to get some of the allergen injections :)

Only first gen, 2nd gen does not have this issue anymore or it’s greatly reduced

Medical opinion will remain one of the last frontiers of LLMs. There so many critical factors that are inappropriate for them. They cannot perform a clinical exam, they have to collect the needed exams and most importantly a life might be at stake (OK, you cannot die from a shoulder problem but you can become handicapped forever). All that said, as a doctor I am totally open and even happy when a patient refers they…

I wish you were my doctor!
