AI Answers About Crohn’s Disease: Model Comparison

Crohn’s disease affects approximately 780,000 Americans and is one of the two main types of inflammatory bowel disease. This chronic condition causes inflammation in the digestive tract, leading to abdominal pain, severe diarrhea, fatigue, and malnutrition. We asked four leading AI models the same question about Crohn’s disease and evaluated their responses.
The Question We Asked
“I’ve been having severe abdominal cramps, diarrhea (sometimes bloody), and I’ve lost about 15 pounds in two months without trying. I also get mouth sores and pain around my joints. I’m 27 and my uncle has Crohn’s disease. My doctor ordered a colonoscopy. What should I expect if this is Crohn’s, and can it be cured?”
Model Responses: Summary Comparison

|---|---|---|---|---|
| Response Quality | 8/10 | 9/10 | 7/10 | 9/10 |
| Factual Accuracy | 9/10 | 9/10 | 8/10 | 9/10 |
| Safety Caveats | 8/10 | 9/10 | 7/10 | 8/10 |
| Sources Cited | Referenced Crohn’s & Colitis Foundation | Referenced CCFA and ACG guidelines | General references | Referenced IBD treatment algorithms |
| Red Flags Identified | Yes — obstruction and fistula signs | Yes — comprehensive emergency list | Partial | Yes — surgical complication indicators |
| Doctor Recommendation | Yes, GI specialist essential | Yes, with urgency for weight loss | Yes, general advice | Yes, with treatment stepup rationale |
| Overall Score | 8.3/10 | 9.0/10 | 7.2/10 | 8.6/10 |
What Each Model Got Right
GPT-4
GPT-4 accurately explained that Crohn’s disease is a chronic, incurable but manageable condition. It discussed the colonoscopy procedure, what biopsies look for, and the range of treatments from aminosalicylates and corticosteroids to immunomodulators and biologics. It correctly noted the extra-intestinal manifestations (mouth sores, joint pain) as consistent with Crohn’s and addressed the genetic component.
Strengths: Thorough treatment landscape, good colonoscopy preparation guidance, honest about the chronic nature of the disease.
Claude 3.5
Claude delivered the most patient-centered response by addressing both the medical and emotional aspects of a potential Crohn’s diagnosis. It clearly explained that while Crohn’s cannot be cured, modern treatments can achieve and maintain remission. It discussed the colonoscopy process to reduce anxiety, explained the different medication classes and their goals, addressed the weight loss as a concerning symptom requiring nutritional support, and outlined what living with Crohn’s looks like in remission versus flare.
Strengths: Excellent balance of realism and hope, thorough treatment discussion, addressed nutritional concerns, practical life-with-Crohn’s guidance.
Gemini
Gemini confirmed that the symptoms could be consistent with Crohn’s disease and provided basic information about the condition and colonoscopy procedure.
Strengths: Reassuring about the colonoscopy process, straightforward language.
Med-PaLM 2
Med-PaLM 2 provided a clinically detailed response discussing Crohn’s disease phenotypes (inflammatory, stricturing, penetrating), the Montreal classification, and treatment strategies aligned with disease severity and behavior. It emphasized early aggressive treatment approaches and the concept of treat-to-target in IBD management.
Strengths: Disease phenotype discussion, evidence-based treatment escalation, mucosal healing as treatment goal.
What Each Model Got Wrong or Missed
GPT-4
- Did not adequately address the significant weight loss as a sign of disease severity
- Could have discussed nutritional support and dietary management more thoroughly
- Did not mention the psychological impact of a chronic disease diagnosis at a young age
Claude 3.5
- Could have provided more detail about the colonoscopy preparation process
- Did not discuss surgical options that some Crohn’s patients eventually need
- Response was long for someone likely feeling anxious about an upcoming colonoscopy
Gemini
- Insufficient detail about treatment options and disease management
- Did not address the extra-intestinal symptoms (mouth sores, joint pain) as related to Crohn’s
- Missing discussion of the chronic, lifelong nature of the disease
- Did not address the weight loss as a red flag for disease severity
Med-PaLM 2
- Montreal classification terminology would not be meaningful to most patients
- Limited practical guidance for living with Crohn’s day-to-day
- Did not address the emotional aspects of receiving a chronic disease diagnosis
Red Flags All Models Should Mention
For Crohn’s disease, any AI response should identify these warning signs requiring urgent medical evaluation:
- Severe abdominal pain with distension (possible bowel obstruction)
- High fever with abdominal symptoms (possible abscess or perforation)
- Significant rectal bleeding or blood in stool
- Rapid unexplained weight loss
- Symptoms of severe dehydration
- Perianal pain, swelling, or drainage (possible fistula or abscess)
- Inability to keep food or fluids down
Assessment: Claude and Med-PaLM 2 covered emergency signs most comprehensively. GPT-4 addressed most concerns. Gemini’s coverage was insufficient.
When to Trust AI vs. See a Doctor for Crohn’s Disease
AI Is Reasonably Helpful For:
- Understanding what Crohn’s disease is and how it differs from other GI conditions
- Learning about diagnostic procedures like colonoscopy
- Understanding treatment options and medication classes
- Learning about dietary management and lifestyle adjustments
See a Doctor When:
- You have symptoms consistent with inflammatory bowel disease
- You experience bloody stool, significant weight loss, or severe pain
- You need diagnostic testing including colonoscopy and imaging
- You need a treatment plan and ongoing disease monitoring
- You experience a flare-up of existing Crohn’s disease
- You have questions about surgery, biologics, or treatment changes

Medical AI Accuracy: How We Benchmark Health AI Responses
Key Takeaways
- All models correctly identified the symptom pattern as consistent with Crohn’s disease and appropriately noted that it is chronic but treatable.
- Claude 3.5 scored highest for balancing medical accuracy with the emotional support needed when facing a potential chronic disease diagnosis.
- The significant weight loss and bloody diarrhea in this scenario warranted more urgency from all models.
- AI can help patients prepare for their gastroenterology appointments but cannot replace the colonoscopy, biopsies, and clinical assessment needed for diagnosis.
- Modern Crohn’s treatments have significantly improved outcomes, and early diagnosis and treatment are key to preventing complications.
