Tests are normal. What type of bowel dysfunction does Miss Baldwin most likely have and what is your first recommendation for treatment?

• A. Osmotic diarrhea and eliminate lactose containing products
• B. Motility disorder and add daily 25-30 grams of fiber
• C. IBS-diarrhea predominant and keep a detailed food diary
• D. IBS-Diarrhea predominant and take Imodium daily

Answer: (C)

This scenario points to irritable bowel syndrome with diarrhea predominance. The pattern of abdominal pain that is closely linked to defecation, a change in stool frequency and liquidity, mucus in the stool, and a normal workup over several months fits IBS-D rather than an organic disease or a simple osmotic or intolerance issue. The best first step in management is to keep a detailed food and symptom diary. Tracking what you eat and when symptoms occur helps identify specific triggers or patterns (such as dairy, high-FODMAP foods, caffeine, or fatty meals) and guides individualized dietary adjustments. This approach often reduces symptoms without medication and lays a foundation for further tailored strategies, like selective dietary changes (for example, lactose reduction or a low-FODMAP plan) alongside education and reassurance. Why the other options aren’t as fitting: osmotic diarrhea wouldn’t align with the clear pain-relief-with-defecation pattern and often points to a different mechanism or specific trigger; lactose elimination targets a specific intolerance rather than a functional, symptoms-driven pattern; a general motility disorder is a broader category and doesn’t specify the diarrhea-predominant IBS presentation; and taking a medication like Imodium daily treats symptoms but doesn’t address the underlying triggers and isn’t the recommended first-step approach after identifying IBS-D.
