Acid Reflux and GERD
Acid reflux occurs when the acid in your stomach backs up, or refluxes, into your esophagus, causing feelings of heartburn.
Gastroesophageal Reflux Disease (GERD) is chronic acid reflux that occurs regularly (more than twice a week for a few weeks). GERD affects about 20% of Americans and could lead to more serious health problems over time.
