GERD is an acronym for gastroesophageal reflux disease, which is characterized by the flow of digestive juices, also called acids, from the stomach into the esophagus. Food flows down the esophagus and into the stomach, where digestive processes take place. At the bottom of the esophagus, the lower esophageal sphincter normally contracts sufficiently to prevent stomach acids from traveling into the esophagus. When it does not close sufficiently, stomach acids and food can migrate, or reflux, into the esophagus.
Reflux Symptoms
The reflux of stomach acids and food can cause a taste of regurgitated food at the back of the mouth. This taste can also spread into the throat. There can also be the taste of a sour liquid. There can be a burning sensation in the chest, which is also known as heartburn or acid indigestion. There can also be a sensation of a lump in the throat.
Recurrence
Acid reflux, which is also called gastroesophageal reflux, can be experienced by anyone. According to the National Institute of Diabetes and Digestive and Kidney Diseases, occasional gastroesophageal reflux is common. The recurrence of gastroesophageal reflux twice per week or more on a consistent basis elevates gastroesophageal reflux to gastroesophageal reflux disease.
Other Symptoms
Some adults have gastroesophageal reflux disease without the symptom of heartburn. Also, most children under the age of 12 do not have the heartburn symptom. The symptoms that can occur in these circumstances are a dry cough and trouble with swallowing. There can also be asthma symptoms. Asthma symptoms include wheezing and tightness in the chest. Other asthma symptoms include trouble with sleeping due to shortness of breath.
