IBS

A functional medicine approach to healing Irritable Bowel Syndrome, from the #1 New York Times bestselling author of Hashimoto’s Protocol

You don’t have to accept bloating, cramping, urgency, or pain as your “normal.” When clinical pharmacist Izabella Wentz was first diagnosed with irritable bowel syndrome, she was told her digestion was simply “overly sensitive.” For years, she assumed everyone’s stomach hurt after eating. Like many people, she tried to live with the discomfort, until she discovered there were real, treatable reasons for her symptoms. And the same can be true for you.

In this groundbreaking guide, Dr. Wentz shares her signature Root Cause approach to unraveling the mystery of IBS. While conventional medicine may label symptoms as “IBS” and prescribe a medication or two, Wentz reveals how this diagnosis is often a catch-all term that overlooks underlying imbalances, ones that can be identified, addressed, and resolved. For some, the root cause may be an enzyme deficiency. For others, it may be toxic exposures, bacterial overgrowth, food sensitivities, hidden infections and other rarely investigated causes. In this comprehensive and compassionate book, you’ll learn how to uncover the true source of your symptoms and create a personalized healing plan to restore your gut and your life.

Inside, you’ll discover how to:

● Understand what normal digestion really looks like
● Identify potential root causes behind IBS symptoms
● Explore testing options—from gluten intolerance and SIBO to enzyme function and triggering infections
● Remove reactive foods and triggers with targeted nutrition strategies
● Restore microbial balance
● Rebuild digestive function with tailored supplements and lifestyle shifts
● Manage symptoms gently while you work toward lasting healing

Whether you’ve been struggling with IBS for years or were just diagnosed, this is your invitation to dig deeper, heal smarter, and reclaim your energy, confidence, and well-being—with guidance from one of the world’s leading voices in root cause healing.
