Is Gen AI replacing the family physician?
A few years ago, doctors used to joke that patients came to see them for a ‘second opinion’ after self-diagnosing their ailments using Google search. Indeed, nearly 8 in 10 adults in the U.S. turn to the internet for answers to health questions. However, instead of scrolling through websites, many people find answers in the AI-generated summary that appears at the top of their search results. Many more are increasingly turning to AI chatbots like ChatGPT, Claude, and Gemini, to ask health questions, questions they used to ask their healthcare professionals before a visit to the doctors’ office became so expensive.In 2026, more than 1 in 5 adults worldwide now use a Gen AI tool to ask health questions or diagnose a medical ailment. But Gen AI is no doctor. Gen AI did not spend ten years at medical school followed by a grueling fellowship, and large language models (LLMs) upon which GPTs are based, can be wrong and make mistakes since they are only as good as the data they digest.
The old adage that ‘if it’s on the internet then it has to be true’ is a long-forgotten premise. The internet is full of mis- and dis- information and this is the data that is used to train Gen AI models. AI maybe biased, is prone to hallucinations, and for repeating mis-information, even though it always sounds so confident and authoritative in its proclamations.
In essence, diagnosing and treating illness is far too complex for a machine. A machine can't examine you or run tests the way a healthcare professional can, and it doesn't have the ability to reason like a human or explain how it came to a conclusion. These qualities are necessary for making safe and accurate medical decisions and that is why in the fancy new age of AI, we still have medical doctors.

But don’t medical doctors use AI to help diagnose patients?
Yes, clinical decision support systems are growing in capability and assist doctors to diagnose ailments and make recommendations based upon vast lakes of clinical patient data. These medical systems are based upon LLMs too, but many levels above a Gen AI chatbot. They also have access to a patient’s complete medical record and medical history which is critical. But this is a human-machine partnership and ultimately it is the human who knows best, has the medical degree and training, and has the final word. Trust me you wouldn’t want it any other way!So why are so many Americans turning to Gen AI?
The US has the singularly most expensive healthcare system in the world. As a country we spend close to 20% of GDP on healthcare services and yet in some states we have higher infant and maternal mortality rates than many developing countries. The average American lives a shorter and sicker life than those who reside in other OECD countries, is prone to more compound diseases, and consumes many more medications. Meanwhile, medical bills are the number one cause of personal bankruptcy in the country. It’s no wonder then, that many Americans do their best to avoid the doctor unless it’s an absolute emergency - even when they are lucky enough to have health insurance. Deductibles, co-pays, co-insurance, and the absurd price of pharmaceuticals make US healthcare unaffordable and undesirable.While basic Gen AI plans are free, most Americans are shelling out $20 per month on their plan if they have one. There are of course many different Gen AI platforms and subscription plans to choose from among OpenAI ChatGPT, Anthropic Claude, Google Gemini, and others. Compare that to healthcare where the average monthly premium for private health insurance, without subsidies, for a family of four is about $1,800 and you can see why Americans are flocking in large numbers to 'Doctor AI' rather than their Primary Care Physician. The cost of an AI subscription or token is trivial compared to a visit to the doctor, where merely walking through the door will cost you somewhere between $25 and $300 before any tests or treatments are received.
The Dangers of relying on advice from Gen AI
A lawsuit this week demonstrates the dangers of relying on Gen AI for medical care. A 55 year old man from Florida claimed that medical advice he received from ChatGPT almost killed him. Several weeks before falling severely ill, he consulted the chatbot about recurring dizzy spells and bouts of blood pressure instability - symptoms that eventually led to the build-up to a near-fatal pulmonary embolism. He claimed ChatGPT mis-diagnosed him and told him not to seek medical help despite efforts from family members and friends to make him go to hospital.In his suit against OpenAI the maker of Chat GPT, Scott Winters claimed to be a regular ChatGPT user who came to rely it on it for medical advice. His eventual emergency medical treatment and lengthy hospitalization however, led to massive medical bills and to the loss of his home and his career. He faces a long and expensive recovery the suit claims.
ChatGPT's terms of use stipulate that users should not treat the platform as a 'sole source of truth' yet many like Winters, continue to have an unhealthy reliance on ChatGPT and other chatbots. Gen AI platforms can prove to be a valuable research assistant and helpful tool for summarizing ideas or getting big-picture information. AI can be extremely useful in preparing questions to ask your care team but these tools are not and never will be a replacement for real healthcare professionals.
