Bile reflux. Endoscope view of bile (yellow, lower centre) in the stomach. Bile reflux is a condition that occurs when bile flows upward (refluxes) from the small intestine into the stomach and oesophagus. Bile, a digestive juice made in the liver, aids the digestion of lipids in the duodenum (first part of the small intestine). Symptoms include nausea, heartburn and vomiting bile. Unlike acid reflux, it usually cannot be completely controlled by changes in diet or lifestyle. Instead, it is most often managed with medication or, in severe cases, with surgery.
