Chronic bloating, cramping, and alternating diarrhea and constipation that worsen with stress and certain foods are consistent with irritable bowel syndrome (IBS), which affects 10-15% of the global population and is managed through dietary changes like the low-FODMAP diet, stress reduction, and sometimes medications such as antispasmodics (ACG Guidelines). Consult your doctor to rule out celiac disease, inflammatory bowel disease, or other conditions that mimic IBS before starting self-treatment.

We compared four AI models on a typical digestive health 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?”

Model Responses: Summary Comparison

Criteria	GPT-4	Claude 3.5	Gemini	Med-PaLM 2
Response Quality	8/10	9/10	7/10	8/10
Factual Accuracy	9/10	9/10	8/10	9/10
Safety Caveats	7/10	9/10	7/10	8/10
IBS Discussion	Accurate	Thorough with Rome IV criteria	Basic	Clinical precision
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.
