GERD (Gastroesophageal Reflux Disease)
GERD is a chronic digestive disorder where stomach acid frequently flows back into the esophagus, causing irritation and heartburn. It is a more severe, persistent form of acid reflux that can lead to complications if left untreated.
Overview
GERD is a chronic digestive disorder where stomach acid frequently flows back into the esophagus, causing irritation and heartburn. It is a more severe, persistent form of acid reflux that can lead to complications if left untreated.
Understand this condition
In a healthy body, a ring of muscle at the bottom of the esophagus opens to let food into the stomach and then closes tightly. In GERD, this muscle relaxes abnormally or weakens, allowing stomach acid to climb back up into the esophagus. This acid exposure damages the sensitive lining of the esophageal tube over time.
Why it happens
The condition begins when the esophageal valve fails to provide a one-way seal, often triggered by pressure, certain foods, or weight. If the reflux occurs frequently, the repeated acid burns cause chronic inflammation and scarring. Over years, this may progress from simple irritation to structural damage or changes in the tissue.
