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.
Causes of Reflux. Normal, physiologic reflux is thought to be caused by relaxation of the muscle between the esophagus and stomach, the lower esophageal sphincter (LES). In infants, the LES is thought to strengthen with time as reflux diminishes.
