Diarrhea-predominant irritable bowel syndrome (D-IBS) requires a positive diagnosis using Rome criteria, not exclusion. Unnecessary investigations often yield normal results, impacting symptom evolution.
Area of Science:
- Gastroenterology
- Functional Gastrointestinal Disorders
Context:
- Diarrhea-predominant irritable bowel syndrome (D-IBS) diagnosis is often made through exclusion.
- Investigations are frequently performed despite normal expected results.
Purpose:
- To emphasize the importance of a positive diagnosis for D-IBS based on Rome criteria.
- To highlight that extensive investigations are often unnecessary and do not influence symptom progression.
Summary:
- D-IBS diagnosis should be positive, adhering to Rome criteria.
- Systematic, exhaustive investigations are not systematically required for D-IBS.
- Normal investigation results do not positively influence symptom evolution in D-IBS.
Impact:
- Promotes accurate D-IBS diagnosis, reducing unnecessary medical testing.
- Guides clinical practice towards evidence-based diagnostic and treatment strategies for D-IBS.
- Potential to decrease healthcare costs associated with superfluous investigations.

Drugs for Treatment of Diarrhea-Predominant IBS
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...
