What is the recommended diagnostic strategy for chronic diarrhea workup?

• A. Use targeted testing based on suspicion and clinical signs
• B. Perform only empiric deworming for all cases
• C. Rely exclusively on imaging
• D. Order the full GI workup for every case

Answer: (B)

The main idea here is to use a targeted, suspicion-guided diagnostic approach for chronic diarrhea rather than blanket or blanket-therapy strategies. Chronic diarrhea has a wide range of possible causes—infectious, inflammatory, malabsorptive, food-related, parasitic, or neoplastic—and what matters most is pulling in clinical clues from history, exposure, age, and physical examination to focus testing on the most likely issues. Starting with targeted testing helps you gather information that will actually change management and avoids the downsides of unnecessary or inappropriate testing. Relying on empiric deworming for all cases, for example, may treat only parasitic causes and miss non-parasitic etiologies, delay correct diagnosis, expose patients to unnecessary medication, and contribute to resistance or side effects. A practical targeted workup uses basic baseline labs and stool studies guided by risk factors and red flags, considers imaging or endoscopy only when indicated, and may incorporate dietary trials or therapeutic responses as part of the diagnostic process. If alarming features develop or the initial targeted tests don’t explain the diarrhea, you then escalate to more comprehensive evaluation.
