Cure8 research brief
People labelled with IBS-D may actually have treatable organic conditions that require different tests and treatments; avoiding diagnostic mistakes can speed appropriate care and reduce unnecessary symptom-focused treatments.
Clinicians following guideline-recommended testing and monitoring can reduce missed diagnoses like microscopic colitis, bile acid diarrhoea, coeliac disease, and early IBD.
Clinicians (gastroenterologists, primary care), researchers on diarrhoeal disorders, adult patients with IBS-D or persistent diarrhoea, and caregivers.
This narrative review summarizes common diagnostic and management errors in patients evaluated for diarrhoea-predominant irritable bowel syndrome (IBS-D) and conditions that mimic it (for example microscopic colitis, bile acid diarrhoea, small intestinal bacterial overgrowth, coeliac disease, exocrine pancreatic insufficiency, early IBD).
It draws on guideline recommendations and a broad literature base (RCTs, meta-analyses, systematic reviews) through 2025 and focuses on lapses in clinical reasoning and guideline adherence that lead to delayed or inappropriate care.
Key points in the review include the importance of considering and testing for common organic mimics rather than assuming functional IBS-D, following guideline-recommended testing (stool, blood, fecal calprotectin, serology, and colonoscopy with biopsy when indicated), and monitoring treatment response and diagnostic uncertainty rather than relying solely on symptom-based management.
The tone is clinical and practice-focused: the article is intended to help clinicians and informed patients recognize when further testing is warranted and avoid common pitfalls.
This entry is based on the PubMed abstract (narrative review, Current Medical Research and Opinion). The review synthesizes literature up to 2025 and guideline statements; it is not a new clinical trial. For specific diagnostic algorithms, consult full guidelines (ACG, AGA, BSG, ECCO) and the full article.
