The AI Answer to Health Questions
Imagine living with a condition where simple questions about diet, symptoms, or medications arise daily, but accessing specialist doctors is challenging.
For the millions worldwide living with Inflammatory Bowel Disease (IBD)—a chronic condition encompassing Crohn's disease and ulcerative colitis—this is their everyday reality. These patients navigate a complex journey of managing unpredictable symptoms, treatment schedules, and lifestyle adjustments, often with limited support between medical appointments.
Enter ChatGPT, the artificial intelligence chatbot that has captured global attention. Could this sophisticated technology become a reliable companion for IBD patients, providing accurate, empathetic answers to their frequently asked questions? This isn't just speculative wonder—scientists have put it to the test, comparing its performance against specialist doctors in a rigorous experimental setup 8 . The results might surprise you and point toward a future where AI plays a significant role in democratizing medical knowledge and supporting patient care.

IBD represents a group of chronic conditions characterized by digestive system inflammation. Unlike temporary stomach bugs, IBD involves lifelong management of symptoms like abdominal pain, fatigue, weight loss, and bowel irregularities.
Patients face not just physical challenges but significant psychological burdens, including anxiety about symptom flares, social isolation, and constant worry about accessing bathrooms.
ChatGPT is a large language model—an artificial intelligence system trained on vast amounts of text data to understand and generate human-like language 3 .
In healthcare contexts, these AI tools show promise for various applications. They're being tested for analyzing medical images, predicting disease progression, and even serving as virtual standardized patients for medical training 3 .
In September 2023, researchers conducted a rigorous evaluation comparing ChatGPT's performance against specialist doctors in answering real IBD patient questions 8 . Their approach was both meticulous and innovative:
Researchers gathered 263 authentic questions from IBD patients, published in the educational book "Q&A on Ulcerative Colitis and Crohn's Disease." These questions covered the full spectrum of patient concerns.
Each question was presented to ChatGPT (using the GPT-3.5 version available at that time) in a new chat session. The prompts were carefully designed to provide necessary context, mimicking how patients might actually use the tool.
Six evaluators (three licensed IBD doctors and three IBD patients) assessed the responses without knowing whether they came from ChatGPT or human specialists.
Researchers performed comprehensive comparisons to determine if differences in ratings were statistically significant, giving weight to their conclusions.
| Aspect | Description |
|---|---|
| Sample Size | 263 distinct patient questions |
| AI Model | ChatGPT (GPT-3.5, August 3 version, 2023) |
| Comparison Group | Responses from 8 specialist doctors + 55 IBD practitioners |
| Evaluators | 3 licensed IBD doctors + 3 IBD patients |
| Assessment Criteria | Accuracy, empathy, completeness, overall quality |
The findings revealed a surprisingly competitive performance from the AI system. In 1,578 direct comparisons, ChatGPT was preferred 48.4% of the time—not far from the specialist doctors' preference rate 8 .
| Evaluation Dimension | ChatGPT Performance | Doctor Performance | Statistical Significance |
|---|---|---|---|
| Overall Quality | 3.98/5 | 3.95/5 | Not significant (P=0.34) |
| Accuracy | No significant difference | No significant difference | Not significant (P=0.63) |
| Empathy | Slightly lower | Slightly higher | Marginally significant (P=0.03) |
| Completeness | Higher | Lower | Highly significant (P<0.001) |
| User Preference | 48.4% | 51.6% | Not statistically different |
Unlike human doctors with limited office hours, ChatGPT provides instant access to medical information 24/7.
ChatGPT's tendency to provide more complete answers means patients receive broader context around their questions.
The consistency in ChatGPT's response quality is particularly valuable for standard medical information.
Like all AI models, ChatGPT can occasionally "hallucinate"—generating confident but incorrect information 5 .
ChatGPT's training data has cutoff dates, meaning it might lack awareness of recent medical advances 5 .
Though its empathetic responses were rated reasonably high, ChatGPT cannot genuinely understand human emotion 8 .
| Limitation | Description | Implication for IBD Patients |
|---|---|---|
| Hallucinations | Generation of confident but false information | Critical need to verify medical advice with doctors |
| Knowledge Cutoffs | Lack of awareness of recent medical advances | Possible outdated treatment recommendations |
| Context Blindness | Difficulty understanding unique patient circumstances | Generic advice that may not suit individual needs |
| Emotional Limitations | Inability to genuinely understand human emotion | Lack of authentic therapeutic relationship |
"The most promising vision for AI in IBD care is as a supplement to human doctors, not a replacement. AI can handle routine information requests, freeing clinicians to focus on complex medical decisions and personal patient relationships."
The evidence suggests that ChatGPT and similar AI tools can indeed become valuable "friends" to IBD patients—particularly for providing accessible, comprehensive medical information around the clock. Its ability to answer frequently asked questions accurately and thoroughly makes it a promising resource for patients seeking immediate guidance between medical appointments.
Important: The technology works best as a supplementary resource rather than a replacement for specialist care. Its occasional hallucinations, knowledge limitations, and inability to provide genuine human empathy mean that medical professionals remain essential for diagnosis, treatment planning, and emotional support.
As AI technology continues to evolve, we can anticipate more sophisticated medical chatbots specifically trained on verified medical literature and capable of recognizing their limitations. For now, IBD patients can cautiously embrace these tools for general information while maintaining their all-important relationships with human healthcare providers. The future of IBD care likely lies not in choosing between human expertise and artificial intelligence, but in skillfully integrating both to provide comprehensive, accessible, and compassionate patient support.
The study referenced in this article evaluated ChatGPT's performance based on its September 2023 capabilities. As AI technology evolves rapidly, current versions may demonstrate different strengths and limitations. Always consult healthcare providers for personal medical advice.
