Why SIBO Breath Tests Are Fundamentally Unreliable: And How to Actually Identify What's Happening in Your Gut — The Problem Nobody Wants to Say Out Loud

You took a SIBO breath test. Maybe you tested positive and started antibiotics, herbals, or a restrictive diet. Maybe you tested negative and were told you don&#8217;t have SIBO, so your symptoms must be IBS, anxiety, or something else entirely. Either way, you&#8217;re still bloated. You&#8217;re still gassy. Your digestion is still broken. Here&#8217;s what most people don&#8217;t understand: the breath test wasn&#8217;t designed to diagnose what&#8217;s actually happening in your gut. It was designed to measure something much narrower. The gap between what it measures and what you actually have is where the real problem lives. This is not conspiracy. This is mechanics. And once you understand the mechanics, you&#8217;ll see why these tests fail not occasionally but systematically. More importantly, you&#8217;ll understand how to gather real data about what&#8217;s actually happening in your small intestine.
