Acid Reflux Diagnosis and Symptoms
Acid reflux happens when stomach contents flow back into the esophagus, the tube connecting your mouth to your stomach. It often causes heartburn and regurgitation. Some people also experience chest discomfort, trouble swallowing, or throat symptoms. Occasional reflux is common. But when reflux causes ongoing symptoms or complications, doctors may diagnose gastroesophageal reflux disease (GERD).
