Acid Reflux: Retrograde flow of gastric acid and pepsin into the esophagus causing retrosternal burning (heartburn), acid regurgitation, or atypical extra-esophageal symptoms.
Reflects lower esophageal sphincter (LES) transient relaxations, hiatal hernia, or delayed gastric emptying; persistent reflux leads to erosive esophagitis, strictures, or Barrett's Esophagus.

Clinical Red Flags
Seek urgent medical attention at an emergency department or primary care clinic if you present with any of the following symptoms:
- Progressive difficulty swallowing (dysphagia) or painful swallowing (odynophagia)
- Hematemesis, melena, or unexplained iron deficiency anemia
