If IBS diarrhea is running your life, it’s time to get to the root cause. In this episode, dietitians Jessie Wong and Brooke Keenan explain the three main types of diarrhea in IBS—flare-up, overflow, and food intolerance—and how to tell which one you have.

You’ll hear real-life case studies and learn how to spot the signs of constipation-driven diarrhea, hidden food intolerances, and digestive patterns that standard treatments often miss.

In This Episode, You’ll Learn:

✔ Why diarrhea is sometimes caused by constipation

✔ The difference between overflow vs. flare-up diarrhea

✔ How food intolerances like gluten or FODMAPs play a role

✔ Why the low FODMAP diet isn’t always the right approach

✔ Tools like Imodium, fiber, and stress management for relief

✔ How clients like Kinsey, Jessica, and Kathy found lasting results
