Mistakes in the management of irritable bowel syndrome-diarrhoeal subtype and mimics: a narrative review.

Quick Summary

This narrative review examines common diagnostic and treatment mistakes made when managing IBS-D (irritable bowel syndrome with diarrhea) and conditions that mimic it. The authors analyzed medical literature from 1997 to 2025 to identify errors that lead to misdiagnosis, delayed treatment, and inappropriate care.

What Was Studied

Researchers reviewed published studies and clinical guidelines to identify frequent mistakes in diagnosing and managing IBS-D and conditions that can look like it, including microscopic colitis, bile acid diarrhea, SIBO (small intestinal bacterial overgrowth), celiac disease, pancreatic enzyme deficiency, and several other disorders. The review synthesized evidence from randomized controlled trials, meta-analyses, systematic reviews, and expert consensus statements spanning nearly three decades.

How the Study Was Conducted

The authors conducted a narrative review (a broad overview rather than a systematic analysis) of medical literature published between 1997 and 2025, including guidelines from major gastroenterology organizations (American College of Gastroenterology, American Gastroenterological Association, British Society of Gastroenterology, European Crohn's and Colitis Organisation). They focused on identifying common errors in clinical reasoning and guideline adherence when diagnosing and managing IBS-D and similar conditions.

Key Findings

• IBS-D shares symptoms with many other conditions, making misdiagnosis common and leading to delayed proper treatment
• The most serious mistakes occur when doctors fail to follow clinical guidelines and make errors in diagnostic reasoning
• Common conditions mistaken for IBS-D include microscopic colitis, bile acid diarrhea, SIBO, celiac disease, pancreatic enzyme problems, lactose intolerance, and early inflammatory bowel disease
