GERD â or gastroesophageal reflux disease â is the medical term for acid reflux. And it can cause, among other symptoms, heartburn in the chest. Occasional heartburn can happen after a large meal or with foods you are sensitive to, but GERD is diagnosed when the burning happens frequently or even continuously.
Gastroesophageal Reflux Disease (GERD) is caused by reflux of stomach acid into the esophagus. In most sufferers this is due to a relaxation of the lower esophageal sphincter (LES) that opens to allow food and liquids to pass into the stomach, and closes to prevent food and stomach acid from flowing back into the esophagus.
