Gastroesophageal Reflux Disease

📖What is Gastroesophageal Reflux Disease?

Gastroesophageal reflux disease, commonly known as GERD, is a chronic digestive disorder in which stomach acid frequently flows back into the oesophagus, irritating its lining and causing persistent symptoms. It occurs when the lower oesophageal sphincter, the muscular valve that normally prevents backward flow of stomach contents, weakens or relaxes inappropriately. While occasional acid reflux is common and generally harmless, GERD is diagnosed when reflux occurs frequently enough to cause troublesome symptoms or damage to the oesophageal lining. Left untreated over many years, chronic acid exposure can lead to complications including oesophageal inflammation, strictures, or a precancerous change called Barrett's oesophagus. Lifestyle modification combined with acid-suppressing medication effectively controls symptoms for most people.
