Gastroesophageal Reflux


Retrograde flow of gastric juice (GASTRIC ACID) and/or duodenal contents (BILE ACIDS; PANCREATIC JUICE) into the distal ESOPHAGUS, commonly due to incompetence of the LOWER ESOPHAGEAL SPHINCTER. Gastric regurgitation is an extension of this process with retrograde flow into the PHARYNX or MOUTH.
