Acid reflux is a disease characterized by the abnormal reflux or rise of gastric contents from the stomach into the esophagus resulting in chronic symptoms and mucosal damage. So it occurs when one of the two closures or sphincters in the esophagus fail to remain sealed after food or liquid intake and the contents get spilled into your larynx and pharynx instead of in your stomach.
Causes of acid reflux
Acid reflux is often caused by temporary or permanent alterations in the lining that actually separates the esophagus from the stomach. It is the ineffectiveness of the lower esophageal sphincter [LES] or the temporary LES relaxation connected to hiatus hernia that causes severe acid reflux. In adults, the most common symptom of acid reflux is acute heartburning sensation caused by acid resting in the esophagus. The painful sensation continues behind the sternum or breastbone. Another common symptom of acid reflux is esophagitis, which means that the person suffers an inflammation of the lining of esophagus. This simultaneously causes swallowing difficulties and chronic chest pains.
