Acid Reflux (GERD)
Acid reflux is when the acid that is normally in your stomach backs up into the esophagus. The esophagus is the tube that carries food from your mouth to your stomach.
When acid reflux causes bothersome symptoms or damage, we call it "gastroesophageal reflux disease" or "GERD."
Heartburn, which is a burning feeling in the chest
Regurgitation, which is when acid and undigested food flow back into your throat or mouth
Having a raspy voice or sore throat
Stomach or chest pain
Nausea or vomiting
