Overview

GERD is a chronic digestive disorder where stomach acid flows back into the food pipe, irritating the lining. It is a more persistent and severe form of common acid reflux.

Understand this condition

The lower esophageal sphincter is a ring of muscle that acts as a valve. When it fails to close properly, stomach acid escapes upward into the esophagus. This acid causes chemical irritation and inflammation to the sensitive esophageal lining.

Why it happens

GERD occurs when the valve between the esophagus and stomach weakens or relaxes inappropriately. Common triggers include fatty foods, caffeine, and nicotine, which further relax this muscle. Over time, the repeated acid exposure can cause scarring or cellular changes in the esophagus.

Real-world scenarios

  • This often appears as a burning sensation in the chest after eating wings.
  • People may notice a sour taste in their mouth upon waking up.
  • It often presents as a dry cough that worsens late at night.
  • This may appear as difficulty swallowing during a large holiday dinner.

Common vs serious explanations

Common
  • Occasional dietary overindulgence or spicy food intake
  • Temporary pressure from tight-fitting clothing or belts
  • Lying down too soon after a large meal
  • Physical strain during heavy lifting or exercise
Serious
  • Erosive esophagitis causing bleeding or ulcers in the throat
  • Esophageal stricture leading to a narrowed food pipe
  • Barrett's esophagus, which is a precancerous change to the lining
  • Heart attack, which can mimic severe indigestion pain
