A lawsuit filed against OpenAI has renewed questions about the role of artificial intelligence in healthcare after a Florida man alleged that advice from ChatGPT delayed him from seeking emergency medical treatment.
The complaint, filed in California, claims the chatbot repeatedly reassured the user about concerning symptoms that were later diagnosed as a life-threatening pulmonary embolism. OpenAI disputes that ChatGPT should be used as a substitute for professional medical care and emphasizes that the chatbot is designed to provide general information—not medical diagnosis or treatment.
The case highlights both the growing popularity of AI tools for health-related questions and the importance of understanding their limitations.
What Does the Lawsuit Allege?
According to court filings, Scott Winters, a 55-year-old pastor from Florida, became a frequent ChatGPT user and increasingly relied on the chatbot when experiencing medical symptoms.
The complaint alleges that he sought advice from ChatGPT after experiencing:
- Recurring dizziness.
- Blood pressure fluctuations.
- Progressive weakness.
- Reduced mobility.
The lawsuit claims ChatGPT repeatedly reassured him that his symptoms were not serious and discouraged him from seeking emergency medical care.
It also alleges that the chatbot referenced Winters’ Christian faith while offering reassurance, which his attorneys argue strengthened his confidence in the responses and contributed to his decision to delay medical treatment.
These allegations have been made in a civil lawsuit and have not been established as facts by a court.
What Happened Afterward?
According to the complaint, Winters was later diagnosed with a massive pulmonary embolism—a condition in which blood clots block one or more arteries in the lungs.
The lawsuit alleges that doctors told him the condition had likely worsened after a prolonged period of immobility.
OpenAI has not admitted liability, and the litigation remains ongoing.
What Is a Pulmonary Embolism?
A pulmonary embolism (PE) is a medical emergency caused when a blood clot—often originating in the legs—travels to the lungs and blocks blood flow.
Without prompt treatment, a pulmonary embolism can:
- Reduce oxygen levels.
- Place severe strain on the heart.
- Cause permanent lung damage.
- Become fatal.
Common symptoms include:
- Sudden shortness of breath.
- Chest pain, especially during breathing.
- Rapid heartbeat.
- Persistent dizziness or fainting.
- Coughing, sometimes with blood.
- Swelling or pain in one leg.
Anyone experiencing these symptoms should seek immediate medical evaluation rather than relying solely on online information or AI tools.
What Is OpenAI’s Response?
OpenAI has reiterated that ChatGPT is not a medical professional and should never replace licensed healthcare providers.
A company spokesperson stated that while AI can help users:
- Understand medical terminology.
- Organize questions for doctors.
- Learn general health information.
It should not be relied upon as the sole basis for decisions involving diagnosis, treatment, or emergency care.
OpenAI’s terms of use also advise users not to depend exclusively on ChatGPT for high-stakes decisions involving:
- Healthcare.
- Legal matters.
- Financial decisions.
- Employment.
Why Can AI Medical Advice Be Risky?
Large language models like ChatGPT generate responses based on patterns in data rather than through clinical examination or diagnostic testing.
Unlike healthcare professionals, AI systems cannot:
- Measure vital signs.
- Perform physical examinations.
- Order or interpret medical tests.
- Observe non-verbal symptoms.
- Assess a patient’s overall physical condition.
Their responses are based entirely on the information provided by users, which may be incomplete or inaccurate.
Because of these limitations, AI can sometimes fail to recognize potentially life-threatening conditions.
Can AI Still Be Useful in Healthcare?
Yes—when used appropriately.
Many healthcare professionals see AI as a tool that can complement medical care rather than replace it.
AI can help users:
- Understand medical terminology.
- Learn about common conditions.
- Prepare questions before appointments.
- Summarize medical information.
- Improve medication reminders.
- Access reliable health education.
However, diagnosis and treatment decisions should remain the responsibility of qualified healthcare professionals.
When Should You Seek Immediate Medical Care?
Medical experts generally recommend seeking emergency evaluation if you experience:
- Chest pain.
- Difficulty breathing.
- Sudden weakness.
- Persistent dizziness or fainting.
- Severe abdominal pain.
- High fever accompanied by confusion.
- Sudden vision, speech, or balance problems.
These symptoms may indicate serious medical conditions that require prompt assessment.
Why This Case Matters
The lawsuit reflects broader questions surrounding the increasing use of generative AI for health-related information.
As millions of people turn to AI assistants for medical guidance, courts, regulators, healthcare providers, and technology companies are increasingly examining:
- The responsibilities of AI developers.
- Appropriate warnings and safeguards.
- User expectations.
- The limits of AI in high-risk situations.
The outcome of the case could influence future discussions about AI safety, consumer protection, and medical liability.
The Bottom Line
The lawsuit against OpenAI underscores the importance of understanding both the capabilities and limitations of AI in healthcare. While the complaint alleges that ChatGPT’s responses delayed treatment for a life-threatening pulmonary embolism, those claims remain before the courts and have not been proven. AI chatbots can be valuable educational tools, but they are not substitutes for licensed medical professionals. Anyone experiencing severe, worsening, or potentially life-threatening symptoms should seek prompt medical attention rather than relying solely on an AI assistant.
TL;DR
- A Florida man has sued OpenAI, alleging ChatGPT’s responses delayed him from seeking emergency medical care.
- The lawsuit claims he later suffered a massive pulmonary embolism caused by multiple blood clots.
- OpenAI says ChatGPT is not a doctor and should never replace professional medical advice.
- The lawsuit contains allegations that have not been proven in court.
- Medical experts continue to advise that AI should supplement, not replace, qualified healthcare professionals.
