ChatGPT suggested insulinoma as a possible explanation for the reported symptoms.
- Configuration
-
Dani described using the most intelligent model available in ChatGPT. The account does not name that model.

- Autonomy

Not assessed
- Workflow
-
Dani entered his symptoms, test results, and medical history into ChatGPT. He used a glucose sensor that recorded readings of 30 to 40 mg/dL, then sought emergency care. An internist confirmed the insulinoma, and a surgical team that treated him removed about two-thirds of his pancreas.
- Human oversight
-
Not assessed
- Relation to AI
-
ChatGPT produced the insulinoma hypothesis from a history that two doctors had reviewed without reaching it. That prompted the glucose sensor and the emergency visit. The diagnosis was made by an internist who, Dani wrote, “lo identificó sin nosotros decirle lo que creíamos que era”. The surgery and recovery were the hospital's work. Dani says he is not a doctor but has “formación biosanitaria de muchos años”, which let him understand what he was doing. Every account traces to his own video.

- Measurement
-
Dani described his symptoms, glucose readings, diagnosis, and surgery in his own video account.
- Setting and sample
-
Not assessed
- Measures
-
Glucose level, symptoms, and response to surgery.
- Comparison
-
Assumed alternative: three years of visits to specialists, including a neurologist, and a primary-care doctor
- Results
-
Dani reports that his symptoms ended after surgery. The comparison is with his earlier three years without a diagnosis, not a controlled assessment.
- Additional value from AI
-
Not assessed
- Limitations
-
No treating clinician or medical record independently confirms the account. The reports do not establish whether the chatbot prevented death.

Follow-up
- Conditions for replication
-
A clinician needs to investigate the suggestion. Here, the suspected condition had a marker that the patient could measure with a glucose sensor, and doctors confirmed it with blood tests.
- Replication attempts
-
2 follow-up entries. Outcome unresolved: 2.
- Later findings
-
The surgery and the disappearance of his symptoms were already in the 3 August 2025 video; no later report on Dani was found, only re-reports of the same story.

Dani describes a tumor that remained undiagnosed for three years. He reports that his symptoms ended after surgery. The reports discuss episodes that could have caused serious harm, but that possibility and the recovery remain supported by his account alone.

- Field
-
Healthcare (rare-disease diagnosis). Consumer use of a general chatbot as a diagnostic aid.
- Purpose
-
ChatGPT is a general-purpose conversational assistant. Dani used it as a diagnostic aid, entering symptoms, results and history. OpenAI told the Mirror that its services “are not intended for use in the diagnosis or treatment of any health condition”. The Economic Times quoted that. So this benefit lay outside the product's stated purpose.
