Why This Free Sample Matters
IBS is often overdiagnosed as “stress” and under-analysed as a clinical syndrome. This note teaches IBS as a functional gut-brain communication disorder, then converts that idea into diagnosis, exclusion of red flags, practical diet advice, and subtype-based treatment.
The strongest part of this topic is clinical discrimination: IBS versus IBD, microscopic colitis, lactose intolerance, celiac disease, parasitic infestation, and other mimics. That is exactly where NEET-PG and AIIMS-style questions become tricky.
What You’ll Learn
- Gut-brain axis logic — why symptoms are real even when endoscopy and routine structure appear normal.
- Rome IV criteria — recurrent abdominal pain, relation to defecation, change in stool frequency, and change in stool form.
- IBS subtyping — IBS-C, IBS-D, IBS-M, IBS-U using stool pattern and Bristol Stool Chart logic.
- Red flags — blood in stool, weight loss, fever, nocturnal diarrhea, anemia, family history, and onset after 50 years.
- IBS versus IBD — fecal calprotectin, rectal bleeding, nocturnal symptoms, protein loss, and inflammatory markers.
- Microscopic colitis trap — normal colonoscopy does not exclude it; biopsy is the key when clinically suspected.
- Indian low-FODMAP approach — foods to reduce, safer alternatives, and why restriction must be followed by reintroduction.
- Drug therapy — IBS-C, IBS-D, spasmodic pain, and anxiety/gut-brain axis pharmacology.
- MCQ practice — clinical reasoning questions with worked explanations.
