Gastroesophageal Reflux Disease (GERD)
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.
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.
