Gastroesophageal reflux disease, commonly referred to as GERD, or acid reflux, is a condition in which the liquid content of the stomach regurgitates (flows up, or refluxes) into the esophagus. The liquid can inflame and damage the lining of the esophagus.
The main symptoms are persistent heartburn and acid regurgitation. Although some people with GERD do not experience heartburn. Instead, they may experience pain in the chest, hoarseness in the morning, or trouble swallowing. They may feel tightness in their throat similar to choking or food lodged in the throat. GERD can also cause a dry cough and bad breath. Only a doctor can diagnose GERD, if you think you have this condition, talk to your doctor.
