An ineffective lower esophageal sphincter could lead to Barrett esophagus.

Question

Quizplus · Accepted Answer

The lower esophageal sphincter (LES) is a muscular ring that controls the flow of food and stomach acid from the esophagus into the stomach. If the LES is weak or ineffective, stomach acid can flow back into the esophagus, causing chronic inflammation and irritation. Over time, this can lead to changes in the cells lining the lower esophagus, increasing the risk of developing Barrett esophagus, a condition in which the cells become abnormal and may eventually lead to esophageal cancer.
