Why IBS-C Treatments Work Differently for Everyone: What Patients Should Know

Why does one IBS-C treatment work for someone else—but not for you?

In this episode of the Gastro Girl podcast, leading gastroenterologist Darren M. Brenner. MD, FACG,  of Northwestern Medicine, explains why treating IBS-C (irritable bowel syndrome with constipation) is not one-size-fits-all.

Using a real-world patient scenario, Dr. Brenner breaks down what may actually be happening inside the body—from gut motility and visceral sensitivity to the brain-gut connection—and why different therapies target different symptoms and pathways.

In this episode, you'll learn:

• Why some IBS-C treatments don't work—or stop working over time

• How over-the-counter and prescription therapies differ

• What newer treatment approaches are designed to do

• Why bloating, pain, and constipation may require different strategies

• The role of diet, pelvic floor therapy, and gut-brain interventions

• How patients can work with their healthcare team to find the right treatment plan

If you've ever felt frustrated, stuck, or unsure about your IBS-C treatment journey, this episode offers practical insights to help you better understand your options and feel more empowered in your care.
