How is bile reflux diagnosed?

Bile reflux will usually involve abdominal symptoms and sometimes esophagus symptoms. While reflux into your esophagus is easy to diagnose based on your symptoms alone, reflux into your stomach will need to be confirmed by imaging tests. Your healthcare provider will probably order an upper endoscopy exam to look inside of your esophagus, stomach and upper small intestine. The endoscope can take tissue samples while it takes images, to test for inflammation, tissue damage and the presence of bile. For reflux into your esophagus, they may take additional tests to distinguish acid reflux from bile reflux.
