- Insulin-like peptide 5 (INSL5) levels are elevated in bile acid diarrhea and IBS.
- INSL5 correlates with stool consistency and urgency.
- Rectal taurocholic acid boosts INSL5 levels rapidly.
- INSL5 may predict response to ondansetron.
- First study to investigate INSL5 in chronic diarrhea.
- Future studies needed to assess INSL5's role in diarrhea severity.
- INSL5 does not rise postprandially, suggesting bile stimuli trigger its release.
