The cause is a weakness of the sphincter muscle between the esophagus and stomach.
This leads to a more prolonged exposure of the esophageal mucosa to gastric fluid than normal.
This allows the doctor to look at the esophagus and the stomach through a scope to be sure the stomach is healthy.
Normally, the lower esophageal sphincter stops stomach acid from entering the esophagus.
On endoscopic examination, retention of saliva in the distal esophagus was noted.
Food enters the mouth and travels through the esophagus to the stomach, located in the upper abdomen.
Patients can also bleed into muscles, into the esophagus , or into the stomach or intestine.
It is the backward flow of acid from the stomach up into the esophagus .
Saliva rinses the esophagus and buffers acid that has splashed out of the stomach.
Repeated exposure of the esophagus to stomach contents leads to esophagitis.
