Did You Know?

Did you know that small intestinal bacterial overgrowth (SIBO) is often mistaken for acid reflux? In my practice, at least half the patients who come in with a reflux diagnosis are actually suffering from SIBO. Why is the mistaken diagnosis so common? The symptoms of the two conditions are very similar and even identical in some cases. Burning upper abdominal pain that can feel like acid reflux is one of the commonest manifestations of SIBO. High levels of gas produced by bacteria in the upper GI tract can cause the lower esophageal sphincter to open inappropriately, mimicking acid reflux. To further complicate matters, acid suppressing drugs like proton pump inhibitors (PPIs) are a common cause of SIBO, but since SIBO symptoms are often misdiagnosed as acid-reflux, PPIs are frequently used to treat SIBO, perpetuating the cycle of symptoms. So how can you tell the difference to gain a proper diagnosis?…
