📋Overview

This condition occurs when stomach contents repeatedly move upward into the esophagus, often resulting in irritation of the esophageal lining. It is typically considered a more persistent and severe form of acid reflux that can affect daily life.

The backward flow of acid may happen when the valve at the end of the esophagus does not close properly, allowing gastric juices to escape. While many individuals experience occasional reflux, a clinical diagnosis is often applied when these episodes occur frequently over an extended period.
