<unk> , bile<unk>  (gastritis), duodenogastroesophageal<unk>  (DGER) or duodenogastric<unk>  is a condition that occurs when bile and/or other contents like bicarbonate, and pancreatic enzymes flow upward<unk> es) from the duodenum into the stomach and esophagus.<unk>  can be confused with acid<unk> , also known as gastroesophageal<unk>  disease (GERD). While bile<unk>  involves fluid from the small intestine flowing into the stomach and esophagus, acid<unk>  is backflow of stomach acid into the esophagus. These conditions are often related, and differentiating between the two can be difficult. Bile is a digestive fluid made by the liver, stored in the gallbladder, and discharged into duodenum after food is ingested to aid in the digestion of fat. Normally, the pyloric sphincter prevents bile from entering the stomach. When the pyloric sphincter is damaged or fails to work correctly, bile can enter the stomach and then be transported into the esophagus as in gastric<unk> . The presence of small amounts of bile in the stomach is relatively common and usually asymptomatic, but excessive<unk> ed bile causes irritation and inflammation. Bile<unk>  has been associated with gastric cancer, chemical gastritis and the development of ulcers.
