Sometimes called acid regurgitation; acid reflux is a fairly common condition in which stomach acid seeps backward up into the esophagus, which results in symptoms such as a sour or bitter taste in the mouth or more commonly a burning feeling in the chest (heartburn). These symptoms often last several hours after a meal and then go away. Many people experience acid reflux from time to time, typically after eating certain foods. When acid reflux occurs more often than twice a week, it is called gastroesophageal reflux disease (GERD). This more serious condition and when left untreated can result in problems such as esophagus inflammation (esophagitis) or a precancerous condition known as Barrett’s esophagus. GERD can also worsen chronic cough, insomnia, asthma, and pulmonary fibrosis.
