Digestive complaints — bloating, heartburn, irregular bowel habits — are among the most common reasons for doctor visits and AI health queries. We compared four models on a typical GI question.
The Question We Asked
“I’ve had on-and-off bloating, gas, and loose stools for about 3 months. Sometimes I get crampy abdominal pain that improves after a bowel movement. No blood in my stool, no weight loss. I’m 33, female, otherwise healthy. Could this be IBS? What should I do?”

| Differential Diagnosis | Good | Comprehensive | Limited | Thorough |
| Overall Score | 8.1/10 | 8.7/10 | 7.0/10 | 8.3/10 |
What Each Model Got Right
GPT-4
Correctly identified the symptom pattern as consistent with IBS-D (diarrhea-predominant IBS). Discussed the role of dietary modification (low-FODMAP diet, fiber adjustment), stress management, and the potential role of probiotics. Mentioned that IBS is a diagnosis of exclusion — other conditions need to be ruled out first.
Claude 3.5
Provided the most structured approach. Explained Rome IV diagnostic criteria for IBS in patient-friendly language. Emphasized that while IBS is likely, the symptoms overlap with celiac disease, inflammatory bowel disease (IBD), food intolerances (lactose, fructose), and other conditions that require testing to exclude. Provided a clear recommendation: see your primary care doctor for basic bloodwork (CBC, CRP, celiac panel) and potentially a gastroenterology referral. Addressed the gut-brain connection and the role of stress.
Gemini
Identified IBS as a possibility and recommended seeing a doctor. Less detailed on differentials and management.
Med-PaLM 2
Systematically discussed the differential diagnosis with clinical precision. Mentioned alarm symptoms that should prompt urgent evaluation (rectal bleeding, unexplained weight loss, family history of GI cancers, symptom onset after age 50). Discussed evidence-based IBS treatments including low-FODMAP diet, antispasmodics, and gut-directed hypnotherapy.
What Each Model Got Wrong or Missed
- GPT-4: Could have emphasized more strongly that initial medical evaluation is needed before self-diagnosing IBS
- Claude 3.5: Low-FODMAP diet discussion could have been more practically detailed
- Gemini: Missed celiac disease as a key differential; alarm symptoms were not adequately covered
- Med-PaLM 2: Clinical tone; the gut-brain connection was underaddressed
Alarm Symptoms All Models Should Mention
For GI complaints, AI should identify these red flags requiring prompt evaluation:
- Blood in stool (visible or occult)
- Unexplained weight loss
- Fever
- Nighttime symptoms waking from sleep
- Progressive worsening
- Family history of colorectal cancer or IBD
- New onset after age 50
- Iron deficiency anemia
When to Trust AI vs. See a Doctor for Digestive Issues
AI Is Reasonably Helpful For:
- Understanding common GI conditions like IBS
- Learning about dietary approaches (low-FODMAP, elimination diets)
- Identifying alarm symptoms that warrant evaluation
- Understanding what to expect from GI testing
See a Doctor When:
- Symptoms persist beyond a few weeks
- Any alarm symptoms are present
- You have not had a basic medical evaluation for your symptoms
- Dietary modifications are not improving symptoms
- You want a formal diagnosis
Key Takeaways
- All models correctly identified IBS as the most likely diagnosis but varied in their emphasis on the need for medical evaluation to exclude other conditions.
- Claude scored highest for structuring the response around the need for medical evaluation first, then self-management.
- The critical clinical point — IBS is a diagnosis of exclusion — was well covered by Claude and Med-PaLM 2.
- Celiac disease screening is particularly important in this demographic (young female with GI symptoms) and was missed by Gemini.
