While GERD is often associated with esophageal issues, SIBO can be an unexpected culprit. When bacteria overgrow in the small intestine, they can cause bloating, increased abdominal pressure, and delayed stomach emptying – all of which can contribute to GERD symptoms. The gases produced by these bacteria can also disrupt normal digestion, leading to discomfort and reflux. If you're struggling with persistent GERD despite lifestyle changes and medication, it may be worth discussing SIBO with your healthcare provider. Breath testing can help diagnose SIBO, and treating it may bring much-needed relief from GERD symptoms.
