Acid reflux is a common condition that features a burning pain, known as heartburn, in the lower chest area. It happens when stomach acid flows back up into the food pipe. Gastroesophageal reflux disease (GERD) is diagnosed when acid reflux occurs more than twice a week.One common cause of acid reflux disease is a stomach abnormality called a hiatal hernia. This occurs when the upper part of the stomach and LES move above the diaphragm, a muscle that separates your stomach from your chest. Normally, the diaphragm helps keep acid in our stomach.
