How Does GERD Disease Happen?

Acid reflux happens whenever the lower sphincter in the stomach ceases to function properly. Gastroesophageal reflux disease (GERD disease), which is also known as acid reflux syndrome, is the malfunctioning of the sphincter, as a result allowing the acid to back up towards the esophagus and mouth. This disorder can sometimes be chronic and may also be a precursor or perhaps sign of cancer of the esophagus.
