Heartburn, GER, GERD treatments should be discussed with doctor
Heartburn and gastroesophageal reflux (GER) occur when the lower esophageal sphincter opens spontaneously or does not close properly, allowing stomach contents to rise up into the esophagus. GER is also called acid reflux or acid regurgitation, and when it occurs, food or fluid can be tasted in the back of the mouth and may cause a burning sensation in the chest or throat.
