What Causes IBS-D? Gut-Brain Signals, Motility, and Stress (Part 1)
17m | Jun 16, 2026What causes IBS-D? If you've ever planned your day around bathroom locations or felt like your gut has a mind of its own, you're not alone. In this first episode of a new series, Dr. Mike Hauman addresses Irritable Bowel Syndrome with diarrhea predominance (IBS-D)—a common, frustrating, and often deeply misunderstood condition.
Dr. Mike explains what IBS-D is and what it is not, clarifying that it is a disorder of gut-brain interaction rather than a structural disease. He discusses the common drivers, including motility issues, nervous system hypersensitivity, microbiome changes, and the powerful connection between stress and digestive symptoms.
This episode offers compassion and clarity for those who have been told "it's all in your head" or dismissed after normal test results. If you're tired of living with unpredictable bowel symptoms and want to understand what's really happening in your body, this conversation provides the foundation you need.
Tune in to learn why your symptoms are real, why they deserve attention, and how to begin tracking your patterns for better care.
