Reading Your SIBO Breath Test: A Plain-English Guide to Hydrogen, Methane, and 3-Gas Results: What the Numbers Mean, Why “Negative” Isn’t Always Negative, and What to Ask Next

You held the report. You still couldn't read it.

Most people meet their SIBO breath test the same way: alone at a kitchen table, holding a page of colored lines and numbers that clearly concern them, with no one to explain what any of it means. The result cost money and a strange morning of breathing into bags, and somewhere in those columns is an answer you cannot reach on your own.

What this book does

Reading Your SIBO Breath Test teaches you to read the report you already hold. In plain language, it explains what the test measures, what hydrogen, methane, and hydrogen sulfide each reveal, and how to score your own lines using the thresholds clinicians actually use. You will learn why a rise matters more than a raw number, why a "negative" result is not always negative, and why a flat line is sometimes the most important pattern on the page.

Why this book is different

Rather than a loose collection of tips, this is a structured guide built like a short course. Each chapter introduces one idea, shows the reasoning behind it, works through realistic examples drawn from composite patients, and ends with review questions so you can check your understanding. The interpretation is evidence based and honest about the test's real limits, including the ongoing debate among specialists about how much any breath test can prove.

This book is for readers who:

Have a SIBO breath test result and cannot make sense of it

Were told they are "negative" but still feel unwell

Want to understand hydrogen, methane, and 3-gas results before their next appointment

Care for someone navigating gut symptoms and testing

Want to walk into a clinical conversation prepared with the right questions

Before your next appointment

A breath test is one strong clue among several, worth taking seriously and worth questioning. If you want a clear, practical guide to reading yours with confidence, this book offers a structured place to begin.
