Question

Quizplus · Accepted Answer

Normally, the resting tone of the lower esophageal sphincter maintains a zone of high pressure that prevents gastroesophageal reflux. In individuals who develop reflux esophagitis, this pressure tends to be lower than normal from either transient relaxation or a weakness of the sphincter. Excessive hydrochloric acid and H. pylori can lead to gastritis. Reverse peristalsis is associated with vomiting.
