Chronic Noninfectious Diarrhea: Diagnose, Differentiate, Treat 💩

Chronic diarrhea affects approximately 6–7% of adults, and the vast majority of cases are noninfectious. The most common causes are irritable bowel syndrome with diarrhea and functional diarrhea. A systematic approach matters: • Screen with CBC, CMP, fecal calprotectin, IgA-tTG • Identify alarm features • Biopsy for microscopic colitis when needed • Start with lifestyle + low-FODMAP • Escalate to targeted therapy thoughtfully Precision in diagnosis leads to precision in therapy.   #Gastroenterology #InternalMedicine #EvidenceBasedMedicine
